Does anyone know how to resolve this error? We have added the ED40 record of SET_INV_POST_DATE with the Lawson value of Y and external value of * for all companies but we still get the error message.
I just saw the post from last Sept related to the "SET_INV_POST_DATE" that can be used in ED40. Remember that ED40 records are only used on initial translation of the invoices. Therefore, when an invoice comes in on Feb 27, the ED40 setting will set the post date = to Feb 27 (if I read it right). If that invoice has an error and sits in MA54 until early Mar, and Feb AP has since been closed, you'll receive this message when you clear other MA54 errors because the MA54 record has the Feb 27 date. Not sure if this is what you are experiencing...
(we query, change date, upload for these instances after a month has been closed in AP)
