I need to set and use some context variables in a transformation (written in DTL), but the code is manually written.
When writing the same as BPL I define context variables and they are visible in transformations called by that process.
In something like this my.DTLtransform sets HL7 message fields to values in context variables:
Set qStatus = dtl.Transform(pRequest, .msg)
However, when I create a business process using custom code option, I don't see an obvious option, as well as documentation covering that area.
