Field System Identification & GUIDs

[Clemay300]

Hello!

I was hoping that someone might be able to provide some insight into how to find the GUID values for the standard project fields in Microsoft Project Online. We have been able to locate the values for our "Custom Enteprises Fields", but so far, we cannot find the values for the built-in fields. 

Custom Enteprises Field GUID:

For the custom fields, it looks like you can find the GUID in the "System Identification Data" section, when looking at the custom fields in the PWA Server Settings. 

Is there a way to see this same value for the standard fields? 

Thanks for the help!

The GUID is a unique identifier found in each table. For example, the Project table has ProjectId, Resource table has ResourceId, etc. The following links will provide definitions for the ProjectData or ProjectServer schemas.

Hello @Clemay300 ,

I've not looked for this in detail but I don't think you will easily the field GUIDs for standard fields such as Start, Description etc. A quick look on the PDP using Dev Tools does show the GUID:

I've compared the GUID value for a custom field on the PDP and that matches the custom field GUID so I assume this is the correct GUID for standard fields also.

I hope that helps

Thank you both for the information. I will check out both of those possibilities. I think that a combination of the two will get us what we are looking for. My team inherited a jerry-rigged SharePoint webpart that is pulling in custom project fields, and I think this will allow us to target non-custom fields.
