Hi Enrico,

Thanks for your suggestion. In the end I sent the messages to an EnsLib.HL7.Operation.FileOperation and then wrote some custom criteria in the Message viewer to select the subsets of messages  based on 2.4TXA DocumentType and then resent the messages to a different target.

Regards

Mike

This is very good. A glimpse into the future!. Highly recommended if you have time.

Didn't know about the CSP shell. Thank you!
