An update map handles the reconciliation process for interchange acknowledgements. This map searches the TRLOG table for TA1 information present in the inbound EDI file processed by an inbound map. If TA1 information is present, it updates the original log entry to indicate receipt of a TA1 acknowledgement.
You create the reconciliation map as an any-to-any map. The instructions that follow describe entries on the New Map Definition screen that are specific to the TA1 reconciliation map.
