In this issue: Ace Aviator of the Month News from our product group News from our community Ace Aviator of the Month August Ace Aviator: Jenny Anderson What's your role and title? What are your responsibilities? Iām an Integration Architect at Tietoevry Tech Services, where I work with large enterprise customers to develop integration solutions. For the past two years my main focus has been on cloud and hybrid integrations. I design integration architectures, advise on best practices including security and the chosen architecture, and collaborate closely with development teams to implement and maintain these solutions. Can you give us some insights into your day-to-day activities and what a typical day in your role looks like? My days usually start with scrum meetings across ongoing projects, which help me stay updated on progress, align with teams and prioritize my tasks for the day. After that, I often have customer meetings where I advise on integration strategies, provide architectural guidance or work on pre-sales engagements to scope out potential solutions. Recently, a big focus has been on BizTalk migrations, helping customers modernize their integration platforms by moving to Azure-based solutions. I try to dedicate my afternoons to hands-on technical work, which I really enjoy. Lately, thatās involved working with the new hybrid capabilities in Logic Apps. Itās a great mix of strategic consulting and deep technical implementation, which keeps the role dynamic and rewarding. What motivates and inspires you to be an active member of the Aviators/Microsoft community? Iāve always received a lot of support from the community especially when I was starting out in my career and I still benefit from it today. That generosity and openness made a big impact on me, so I feel itās important to give back whenever I can. For me itās a way to pay it forward and stay connected to a network that has helped me grow both technically and professionally. Looking back, what advice do you wish you had been given earlier that you'd now share with those looking to get into STEM/technology? Donāt overthink it, just start doing! In the beginning of my career, I assumed that everyone else knew everything, and that I couldnāt contribute or be part of certain areas because I didnāt know enough. But the truth is, no one knows everything, and thatās completely okay. The best way to learn is by doing and taking on challenges, making mistakes and growing from experience. I believe confidence comes from action, not from waiting until you feel āready.ā What has helped you grow professionally? One thing that has really helped me grow is surrounding myself with people who have different experiences or areas of expertise, whether at work, in communities, or through networking. Iāve learned a lot simply by asking questions, even the ones that might seem obvious. I also try to say yes to new opportunities, especially when they push me outside my comfort zone. Being an overthinker, Iāve developed a personal mantra: āThink 40%, do 60%.ā It reminds me not to get stuck in planning or doubt, but to take action and learn along the way. That mindset has really helped me move forward. If you had a magic wand that could create a feature in Logic Apps, what would it be and why? If I could use a bit of magic in Logic Apps, Iād want AI to automagically handle all the data mappings. Itās honestly my least favorite part of integration work. It takes forever, itās a bit dull and yet itās always important. So, if AI could just step in and quietly take care of it, I wouldnāt complain. Iāve also heard a few customers ask for a disconnected control plane that can be hosted on-premises. That would be a big win for scenarios where cloud access is limited or compliance rules are extra strict. News from our product group Logic Apps Live July 2025 Missed Logic Apps Live in July?

When working with repeating structures in Logic Apps Data Mapper, you may run into situations where two sibling loops exist under the same parent. What if you need to access data from one loop while youāre inside the other? This is where the Direct Access function, used in combination with Index, can save the day. š§Ŗ Scenario In this pattern, weāre focusing on the schema nodes shown below: šø Source & Destination Schemas (with loops highlighted) In the source schema: Under the parent node VehicleTrips, we have two sibling arrays: Vehicle ā contains VehicleRegistration Trips ā contains trip-specific values like VehicleID, Distance, and Duration In the destination schema: We're mapping into the repeating node Looping/Trips/Trip It expects each tripās data along with a flattened VehicleRegistration value that combines both: The current tripās VehicleID The corresponding vehicleās VehicleRegistration The challenge? These two pieces of data live in two separate sibling arrays. š§° Try it yourself š Download the sample files from GitHub Place them into the following folders in your Logic Apps Standard project: Artifacts ā Source, destination and dependency schemas (.xsd) Map Definitions ā .lml map file Maps ā The .xslt file generated when you save the map Then right-click the .lml file and select āOpen with Data Mapperā in VS Code. š ļø Step-by-step Breakdown ā Step 1: Set up the loop over Trips Start by mapping the repeating Trips array from the source to the destination's Trip node. Within the loop, we map: Distance Duration These are passed through To String functions before mapping, as the destination schema expects them as string values. As you map the child nodes, you will notice a loop automatically added on parent nodes (Trips->Trip) šø Mapping Distance and Duration nodes (context: weāre inside Trips loop) š Step 2: Use Index and Direct Access to bring in sibling loop values Now we want to map the VehicleRegistration node at the destination by combining two values: VehicleID (from the current trip) VehicleRegistration (from the corresponding vehicle) ā”ļø Note: Before we add the Index function, delete the auto-generated loop from Trips to Trip To fetch the matching VehicleRegistration: Use the Index function to capture the current position within the Trips loop šø Index setup for loop tracking Use the Direct Access function to retrieve VehicleRegistration from the Vehicle array. š Direct Access input breakdown The Direct Access function takes three inputs: Index ā from the Index function, tells which item to access Scope ā set to Vehicle, the array you're pulling from Target Node ā VehicleRegistration, the value you want This setup means: āFrom the Vehicle array, get the VehicleRegistration at the same index as the current trip.ā šø Direct Access setup š§ Step 3: Concatenate and map the result Use the Concat function to combine: VehicleID (from Trips) VehicleRegistration (from Vehicle, via Direct Access) Map the result to VehicleRegistration in the destination. šø Concat result to VehicleRegistration ā”ļø Note: Before testing, delete the auto-generated loop from Vehicle to Trip šø Final map connections view ā Step 4: Test the output Once your map is saved, open the Test panel and paste a sample payload. You should see each Trip in the output contain: The original Distance and Duration values (as strings) A VehicleRegistration field combining the correct VehicleID and VehicleRegistration from the sibling array šø Sample Trip showing the combined nodes š¬ Feedback or ideas?

Logic Apps Data Mapper makes it easy to define visual, code-free transformations across structured JSON data. One pattern that's both powerful and clean: using built-in collection functions to compute summary values from arrays. This post walks through an end-to-end example: calculating a total from a list of items using just two functions ā `Multiply` and `Sum`. š§¾ Scenario: Line Item Totals + Order Summary Youāre working with a list of order items. For each item, you want to: Compute Total = Quantity Ć Price Then, compute the overall OrderTotal by summing all the individual totals š„ Input { "orders" : [ { "Quantity" : 10, "Price" : 100 }, { "Quantity" : 20, "Price" : 200 }, { "Quantity" : 30, "Price" : 300 } ] } š¤ Output { "orders" : [ { "Quantity" : 10, "Price" : 100, "Total" : 1000 }, { "Quantity" : 20, "Price" : 200, "Total" : 4000 }, { "Quantity" : 30, "Price" : 300, "Total" : 9000 } ], "Summary": { "OrderTotal": 14000 } } š§ Step-by-step walkthrough šļø 1. Load schemas in Data Mapper Start in the Azure Data Mapper interface and load: Source schema: contains the orders array with Quantity and Price Target schema: includes a repeating orders node and a Summary ā OrderTotal field šø Docked schemas in the mapper š 2. Recognize the repeating node The orders array shows a š icon on <ArrayItem>, marking it as a repeating node. šø Repeating node detection š” When you connect child fields like Quantity or Price, the mapper auto-applies a loop for you. No manual loop configuration needed. ā 3. Multiply Quantity Ć Price (per item) Drag in a Multiply function and connect: Input 1: Quantity Input 2: Price Now connect the output of Multiply directly to the Total node under Orders node in the destination. This runs once per order item and produces individual totals: [1000, 4000, 9000] šø Multiply setup ā 4. Aggregate All Totals Using Sum Use the same Multiply function output and pass it into a Sum function. This will combine all the individual totals into one value. Drag and connect: Input 1: multiply(Quantity, Price) Input 2: <ArrayItem> Connect the output of Sum to the destination node Summary ā OrderTotal 1000 + 4000 + 9000 = 14000 šø Sum function ā 5. Test the Output Run a test with your sample input by clicking on the Open test panel. Copy/paste the sample data and hit Test. The result should look like this: { "orders": [ { "Quantity": 10, "Price": 100, "Total": 1000 }, { "Quantity": 20, "Price": 200, "Total": 4000 }, { "Quantity": 30, "Price": 300, "Total": 9000 } ], "Summary": { "OrderTotal": 14000 } } š§ Why this pattern works š Repeating to repeating: Youāre calculating Total per order š Repeating to non-repeating: Youāre aggregating with Sum into a single node š§© No expressions needed ā itās all declarative This structure is perfect for invoices, order summaries, or reporting payloads where both detail and summary values are needed. š What's coming Weāre working on official docs to cover: All functions including collection (Join, Direct Access, Filter, etc.) that work on repeating nodes Behavior of functions inside loops Real-world examples like this one š¬ What should we cover next? Weāre always looking to surface patterns that matter most to how you build. If thereās a transformation technique, edge case, or integration scenario youād like to see explored next ā drop a comment below and let us know. Weāre listening. š§” Special thanks to Dave Phelps for collaborating on this scenario and helping shape the walkthrough.š Public Preview Refresh: More Power to Data Mapper in Azure Logic Apps
Weāre back with a Public Preview refresh for the Data Mapper in Azure Logic Apps (Standard) ā bringing forward some long-standing capabilities that are now fully supported in the new UX. In our initial announcement, we introduced a redesigned experience focused on usability, error handling, and improved mapping for complex schemas. As we continue evolving the tool, weāre working to bring feature parity with the classic experience, while layering in modern enhancements along the way. With this update, several existing capabilities from the legacy Data Mapper are now available in the new preview version ā so you can bring your advanced scenarios forward with confidence. š ļø Run XSLT Inside Your Data Map The ability to apply XSLT has long been a powerful feature in Logic Apps, and weāre excited to bring Run XSLT support into the new UX. You can now invoke reusable transformation logic from your map, including: Enterprise-grade XSLT Predefined templates or logic from your BizTalk workflows How to try it out: Create a new data map. Right-click on the MapDefintions or Maps folder and click Create new data map Store the XSLT file under Artifacts -> DataMapper/Extension -> InlineXslt. Open the data map and search for Run XSLT in the functions panel. Select the function and simply select the function you want to run from the dropdown Connect to desired destination node. In my case, the function simply adds a "Placeholder" value for the Name node at destination, alongside an "EmployeeType" node. Note that you do not need to connect any source node to the XSLT function given this is custom XSLT logic that will be applied directly at destination node. Upon testing the map, right value is generated in the destination schema š Execute XPath to Extract Targeted Values Execute XPath is now supported in the new experience, giving you control to extract specific values from nested XML structures. This function is particularly useful for: Accessing attributes and nested elements Applying logic based on the structure or content of incoming data How to try it out: Search for Execute XPath in the functions panel. Select the function and add the expression you want to extract Map it to destination node. Here is what the map will look like: The test payload correctly creates multiple Address nodes at destination based on the Address node at source. š§© Use Custom XML Functions Custom XML functions allow you to define and reuse logic across your map. This helps reduce duplication and supports schema-specific transformations. Now that support is available in the new UX, you can: Wrap complex logic into manageable components Handle schema-specific edge cases with ease How to try it out: Add the .xml function file under Artifacts -> DataMapper/Extension -> Functions Open the data map and under Utility category of functions, select the new function. In our case, the xml function is called Age Connect function input to Date_of_Birth node at source and output to Age node at destination. The map will look something like this Test the map and notice that the age is calculated correctly at the destination node š Dark Mode Support in VS Code The new UX now respects Dark Mode in VS Code, giving you a visually cohesive and low-contrast authoring experience ā perfect for long mapping sessions. No extra steps needed ā Dark Mode works automatically based on your VS Code theme settings. āļø How to Enable the New Experience If you havenāt yet tried the new UX: Open your Logic Apps (Standard) project in VS Code Go to Logic Apps (Standard) extension ā Settings ā Data Mapper Select Version ~2 Youāll find detailed walkthroughs in the initial preview announcement blog. š¬ Weād Love Your Feedback Weāre continuously evolving the Data Mapper, and your feedback is key to getting it right ā especially as we bring more advanced transformation scenarios into the new experience. š Submit your feedback here š Found an issue or have a specific feature request? Let us know on GitHub Issues Thanks again for being part of the journey ā more updates coming soon! šš New & Improved Data Mapper UX in Azure Logic Apps ā Now in Public Preview!
Weāre excited to announce that a UX update for Data Mapper in Azure Logic Apps is now in Public Preview! We have continuously improved Data Mapper, which is already generally available (GA), based on customer feedback. Last year, we conducted a private preview to assess the improvements in the new user experience and confirm that we are on the right track in simplifying complex data transformations, including EDI schemas. With the insights gained, we made significant UI enhancements and added features to streamline the mapping process. Feedback We value your feedback to make the Data Mapper even better. Please share your thoughts, suggestions, and overall experience with us through our feedback form. How feedback shaped the Public Preview Throughout the evolution of Data Mapper, we gathered valuable feedback from customers and partners. Key themes that emerged include: Reliability: Ensuring the Data Mapper can handle large schemas and complex transformation logic, including functions. Error handling: Providing real-time validation by allowing users to test payloads and catch errors while authoring maps. Looping: Clearly indicating when repeating nodes are mapped and ensuring complex objects are properly represented Drag & drop enhancements: Improving how connections between nodes are created for better usability. Deserialization & namespace honoring: Ensuring XML deserialization correctly loads mappings without data loss, preserving namespace integrity for seamless schema validation. Weāve incorporated these suggestions into the public preview, ensuring a more refined and user-friendly experience. Whatās new in the Data Mapper UX? 1. Easier navigation Docked schema panels keep you oriented within the data map. Easily search for specific nodes to streamline mapping. 2. Side-by-side function panel Search and use 100+ built-in functions, including mainly: Collection functions (for repeating elements) String manipulations Mathematical operations Conditional logic 3. Automatic looping for repeating nodes When mapping repeating nodes, a new loop connection is automatically added on the immediate parent nodes at source and destination. Repeating parent nodes are denoted by "A1, A2" notation on hover. Note: If the child node in the source has a deeper nesting level than in the destination, you must manually map the connection from the repeating source node to the destination to ensure proper data transformation. 4. Real-time error detection On saving the map, instantly view warnings and errors for missing mappings or incorrect configurations 5. Test Your Map Instantly Preview the output before running your workflow. How to set up and test out the new Data Mapper experience Enable the Preview: Go to your Azure Logic App (Standard) extension -> Settings -> Data Mapper. Select āVersion ~2ā to try out the new user experience. Light theme: Enable "Light Theme" in VS Code before creating a new data map. Dark Theme is not supported, but is on the roadmap and will be prioritized soon. Create a New Data Map: Navigate to the Azure tab on the left-hand panel of your VS Code. Select āCreate New Data Mapā and name it. Once loaded, select the schemas for source and destination. Upload schemas: Upload your source and destination schemas before creating the map (eg .xsd or .json files). Limitations While the new Data Mapper UX brings significant improvements, a few limitations remain: Filter function: The filter function correctly processes numeric conditions when enclosed in quotes (e.g., ">= 10"), but does not behave consistently for string comparisons (e.g., checking if item name = "Pen"). We are actively working on refining this behavior. Custom Functions: Support for custom functions is coming in the next refresh to enhance flexibility in data mapping. Usability enhancements: Improved tooltips, function labels, error messages and other UX refinements are on the way to provide clearer guidance and a smoother mapping experience, especially for complex transformations. Future investments The product is going to continue getting better and we should be adding more features very soon! Some immediate investments include: Enhanced test map experience: Making it easier to validate mappings during development. Panel resizing: Allowing users to have flexibility in viewing larger schemas and functions when multiple panels are expanded.
