Question : Adding a unique identifier to a field for export
I am trying to create a file for import to our accounting program; I am exporting a PO, see example below. The RefNumber below is the unique identifier, so right now, the vendor shows up as Microsoft for all the lines. I need to add something to the query that changes the ref number to "12345-1" for the MS line, "12345-2" for all the Ingram lines, "12345-3" for TechData, and so on.
Payee RefNumber Transaction Date
Microsoft 12345 11/04/2009
Ingram Micro 12345 11/04/2009
Ingram Micro 12345 11/04/2009
Ingram Micro 12345 11/04/2009
TechData 12345 11/04/2009
TechData 12345 11/04/2009
