Symptom
Since you would change the Account assignment data in GSR thus it will not be same as PO Account assignment so you cannot try joining ‘Goods Receipt Item Details (SRMGR_B02)’ with data source ‘Purchase Order Account Assignment (SRMPO_B03)’ based on Purchase Order ID.”
Environment
SAP Business ByDesign
