Problem

-- how to pass attributes from Integrator to Interchange ?

Resolution

1- add the attribute in your "Document Profile" / "Document profile attributes" tab using the following format : B2BXGISend_<attribute name>

ex : B2BXGISend_DocumentType

2- override the attribute in Integrator (in the detector, in the map etc...)

DML ex : setAttribute("B2BXGISend_MyAttribute", "Value1")

3- attribute will be overriden at runtime

4- the prefix B2BXGISend_ is automatically removed and the attribute DocumentType will be available in Interchange / visible in Message Tracker

Note : example shows static value, but of course the value can be content / metadata based
