I have created GRN for a purchase order for which invoice verification is also done. Now i wanted to reduce the value in material cost. IN the MIRO t code, when i select material tab and enter the material number and the value, the system is giving an error message. it is giving an error message as error in account determination. in Transaction key
PRD. the system is posting the value in the price difference account. which should not happen. If i post it to PRD account. The value of the material is not reducing.
Pl let me know the right process to address the issue.
