Hello my dear friends

We've been working with Datapower and WTX in the last months and despite the pretty lack of documentation on the internet specialy, over some tricky scenarios, we're doing good. lol.
The problem now is that some requirements are focused on the error handling especially on DPA errors, and so far I've just found a way to handle the generic error sent by DPA transformation (8 - one or more inputs was invalid).
As we're using this DPA binary transformation only to validate the binary (cobol flat file) data in the file, there is only a input card in my transformation map. Would be very useful to get the trace information, or something like that, giving me more specific information about the error, line number, character index......
Do anyone has overcome this 'issue'?
