Hi - I would like to use a look up table to return an exact match based on multiple criteria (like an AND nesting in an IF function). My data does not have a single key so I need to match 3 different criteria to return the correct result. I am trying to nest multiple XLOOKUP criteria but can't seem to get it to work. Example attached with fake data - I would like to return the right price increase depending on the three criteria: brand, part type and subID. All need to match to return the price increase. Is this possible with an XLOOKUP or is there a better way to do this?
Formula: =XLOOKUP(A2,'LookUp Table'!A1:A9,XLOOKUP(B2,'LookUp Table'!B1:B9,XLOOKUP(C2,'LookUp Table'!C1:C9,'LookUp Table'!D1:D9,none,0)))
|Brand||Part Type||Sub ID||Current Price||Price Change ($)|
|Brand||Part Type||Sub ID||Price Change ($)|

@SusanJackson You may try FILTER() function.
For dynamic spill array use FILTER() with MAP() function.
See the attached file.

Traditional methods also include concatenation of the multipart keys to identify first or final occurrences of a matching record and the use of SUMIFS to aggregate over all matching records.
That said, 365 will permit you to write your own variant of XLOOKUP which is designed to work with multipart primary keys.
XLookupλ = LAMBDA(selectedKey, primaryKey, returnArray, XLOOKUP(TRUE, BYROW(primaryKey, LAMBDA(key, AND(key = selectedKey))), returnArray) )
BYROW tests for a match of all 3 parts of the key before moving to the next record. In order to use the function for multiple lookups a further application of BYROW is required
Worksheet formula = BYROW(foreignKey, LAMBDA(selectedKey, XLookupλ(selectedKey,primaryKey,PriceChangeSource) ))
It is possible to wrap that in a further Lambda to be able to lookup the multiple records using a single function. The formulas are more complicated that the traditional spreadsheet formula but the plus side is that once written they may be reused throughout the workbook and transferred to new workbooks rather than being rebuilt from scratch.
