|Your transaction date (XX/XX/XXXX) is within a period that's been closed. You can add, modify, or delete a transaction only if the date of that transaction is within a period that's open.|
This error occurs when the sync is attempting to post a transaction to a closed period in Intacct.
A. In Bill.com, edit the Invoice Date (or GL Posting Date) of the transaction so that the date is in the current accounting period in Intacct and sync.
B. (not recommended) In Intacct, open the period that includes the date of the transaction and sync again.
Note: If you choose to open the accounting period in Intacct and the error still occurs when the period in Intacct has been opened, the bill may still error due to no update having occurred on the bill since the original error. In this case, make a small edit on the bill in Bill.com (description, invoice number, etc), save and sync.
