In GridView, the IC Primary Vendor field can be found in the table 'I/C Additional Item File' (@N65AIT2).

To view/print the view to list all items with the same Primary Vendor, create a filter with the syntax: {Vendor 1 Code} = "AAAAAA", where "AAAAAA" represents the Primary Vendor Code you want to select.

Make sure you select the actual {Vendor 1 Code} field from the list at the left, rather than typing it in.
