Hi,
SAP does not have such check to check the vendor againest the vendor of PO. It only checks whther the PO no. is valid or not.
However you can build your validation in OB28 to perform such check.
To make the vendor line mandatory for KR document type, you can write the validation as below:-
Step 1:-
Create a message ID via transaction code SE91 for message class /EACC/MSG/ACC_COMP as you want to display to user.
Step 2:-
Go to transaction GGB0 and create the validation step at line item level in Financial Accounting as below:-
Pre Requisits:-
SY-TCODE='F-47'.
Check:-
Create a exit code using user exit and check that vendor in PO is same as vendor in the line item.
For this take the help of ABAPer and create a copy of the program RGGBR000 and code your check here and assign to the application area GBLR in view V_T80D via transaction code SM30.
Message:-
Message created in step 1 as error message.
Step 3:-
Please also check that this validation has active status (Status=1) at line line item level (level 2) for your company code in transaction OB28.
