Customer Field – Item Receipt List on Vendor Bill for Purchase order
I would suggest using a sublist, with the filter setup as created from. Then you set your sublist field to created from.
This would give you a list of item receipts tied to the purchase order that the vendor bill is linked to.
Capturing this in a custom field might be doable, but it depends on what you are trying to do.
Sublist is the best option, create a transaction saved search with criteria type = Vendor bill to show the “applied to transaction” or use the related SO and receipt relationship to show the related receipts to the vendor bill. Add a filter for type = vendor bill or document number and dont check the show filter box, also make sure to check available as sublist. Create a custom tab and sublist and assign the sublist to that tab, it show all the receipts related to that bill.
