In the R/3 System, a credit memo is the reversal of an invoice. In the same way as the system assumes that a corresponding goods receipt was posted or is expected for an invoice, the system assumes that a credit memo is linked to the reversal of a goods receipt. The credit memo is therefore managed on the GR/IR clearing account.
Invoice reversal is a special form of credit memo. The system automatically determines the credit memo amount and the credit memo quantity from the invoice, so that there is no variance between the invoice and the credit memo. The postings made when you reverse an invoice follow the same rules as credit memo postings. This means that an invoice reversal does not necessarily reverse the postings made when the invoice was posted.
The postings that are made for credit memos depend on the goods receipts and invoices posted so far. The following rules apply:
When the account movements are determined, the following items are taken into account:
Invoice Quantity Greater than Goods Receipt Quantity
If the invoice quantity is larger than the goods receipt quantity, the credit memo quantity is split into the quantity that is covered by theinvoice surplus and the remaining credit memo quantity.
The sum of these values is posted to the GR/IR clearing account. The credit memo amount is posted to the vendor account.
Invoice Quantity Smaller than Goods Receipt Quantity
If the invoice quantity is smaller than the goods receipt quantity, the following values are calculated for the credit memo quantity.
This value is posted to the GR/IR clearing account.The credit memo amount is posted to the vendor account.
If the credit memo amount is different to the posting to the GR/IR clearing account, the difference is posted to the stock account or a price difference account, depending on the price control defined for the material.
