The short answer to your question is yes, through the use of terser.
Terser is very useful, and works well. Parse the message with a pipeparser,
create a terser on the message, use the get method. Your messages may

I think having the 3rd component in MSH-9 makes the parse create the message

Is it possible to omit the MDM_T01 in MSH-9?
