Hi,
Many consultant/business user go for directly using of transaction code MR11 but do not understand what it is intended for!
One should know downsides of MR11 including Purpose, How Does it Work, and Results associated. A better approach to correcting differences between GR and IR as following (you can use one of the following approaches instead of MR11).
If goods receipt posted as incorrect document:-
1. Reverse the invoice document created.
2. Go for allowing the incorrect goods receipt to be reversed.
3. Now again post the correct goods receipt.
4. Repost the invoice document.
If the invoice posted as incorrect document:-
1. Reverse the invoice document
2. Repost again the invoice with the correct values/quantities.
NOTE: The transaction code: MR11 is used for clearing the GR/IR balances where GR/IR account can be reconciled during month-end or year-end process. It posts a journal entry of debiting the GR/IR account and credits the corresponding accounts which have the opposite entry. Basically MR11 reverses the accounting entries that created the GR/IR balances.
