We included WBS element in item level incompletion procedure and sent that to PRD. On the same day we revert the change.
So the sales documents are not asking for WBS element but all the old open documents are giving information message V1 105: Field VBAP PS_PSP_PNR is not defined in incompletion procedure ZT while change/display.
Note-We are facing this issue only in PRD.
Users are not able to process any documents as sales document contains multiple line items.
Dear all, your immediate help will be appreciated.
