When using VLOOKUP with data that isn’t made up of unique values you need to combine values to create a unique reference
You can either create additional columns in both data sources and populate with & or CONCATENATE, or you can combine the cell grouping into the VLOOKUP function.
Example – combine Sheet1 columns A and B to create a unique reference, then use VLOOKUP to search for same in Sheet2 (where an additional column has been created and populated with & or CONCATENATE as appropriate)
=IF(ISNA(VLOOKUP(A1&B1,Sheet2!$A:$A,1,FALSE)),"not found","found")
