Hi,
I have a following scenario
material code 123 vendor ABC
Here user had created a po for this material 123 on vendor XYZ and completed the GR and invoice verification.
later, he realized that for this material vendor is MMC not ABC.
Now he wants to cancel this invoice,gr and blocking of PO.
How can i configure this scenario in SAP I.e only material that are linked to particular vendors,system should take into consideration for po creation.
material's that r not linked to vendor's system shoul not allow for po creation.
plz explain step by step process.
