RE: How to void future dated credit memos
The short of it:
1. Update the date to a current open date within your company fiscal period, using SQL
2. Void the document, and
3. Remove the document using a Utility in GP. You need to make sure also that the original document and void document does not reach GL. You need to clean it up just in case it did.
You will not be able to void this document unless you update it in SQL.
But it is strongly recommended you remove this document because it is not only the document date that will have the future date - other dates would have also been affected....
If it got posted to GL, it will be because the Posting Date is within the current fiscal period. The document date affects the SL, and the Posting Date affects GL...
If you are not familiar with using SQL, I would recommend you reach out to your partner.
I hope this helps.
