I am trying to create a rule which filters out ADT_A08 messages, when they have an OBX segment and their EVN.4 is "COD" or EVN.4 is "FIN"
The attempt is:
I have sent messages with EVN.4 COD or FIN and they are filtered out correctly
However if I remove EVN.4 and leave just the OBX filled up, the message passes from the Process to the Operation.
