I was wondering what's the best way to set the AccountingEntityID for an incoming message in ION MT. I have a Document Flow that's associated with 4 different input folders, so 4 Connection Point Documents going to the same Document Flow. The input files are processed identically except for the division. Ideally I want be able to default the AccountingEntityID based on the Connection Point Document that's being processed. Currently I have an xslt map that looks for data in the content to determine how to set the AccountingEntityID. I was hoping there might be some means of setting the BOD header fields based on the Connection Point Document? Thanks.
