Hi
Don't fix the GL by doing journals. If the error originated in payables - fix it in payables and allow everything to post through.
GP does allow you to open closed periods to post transactions - you may have problems if you have done the financial year end roll - but otherwise it should be fine. So depending on your internal rules, you could do either of the following:
- Open the payables and financial period concerned and create all the appropriate reversing transactions - if it can't be done by ticking intercompany boxes, then do it manually in each company. Post all the transactions and the intercompany should come right.
- If you are not allow to open the payables period but you are allowed the financial period, then do a reversing GL journal to correct the financial period which will back out in an open payables period. Then do all the payables corrections and post which will offset the reversing financial journal.
Note: with the second method, if you compare a Historical Payables Trial Balance with the General Ledger for that period you will be out by the amount of the journal, but it will come right in the correcting period.
Bottom line is - fixing it by having a "permanent" credit note should not be an option.
