To simplify document recognition by Trading Networks, you can overwrite attribute values that are extracted from inbound documents with values of your own. To overwrite any custom or system attribute, add the attribute with the new value in the TN_parms parameter of the wm.tn:receive service.Trading Networks extracts the value from TN_parms and saves it to the database to use later. For more information about the wm.tn:receive service, see the webMethods Trading Networks Built-In Services Reference for your release.

You can overwrite the values of system and custom attributes for Transaction, Group, and Envelope document types depending on the type of transaction. Trading Networks displays the new value of the attribute on the Attributes tab in My webMethods.

For more information about document attributes, see Trading Networks Attributes and EDI Documents and the webMethods Trading Networks Administrator’s Guide for your release.
