I am currently using ECC 6.
In one subcontracting PO I found that the rate per unit was changed after making a few GRN. Further GRN were done with new rate.
When the invoicing was being done, the line items in MIRO screen were coming with new rates for all the grn including old ones with old rates and after simulating, the difference between old rates and new rates was debited to inventory account.
please let me know why this is happening. at the time of invoicing, the grn should appear at its original value as per po and not recalculated value.
