Hi Gary, 

There are many ways to do it :)

For example, if you're using DTL you most likely have a single message level transform and multiple segment level transforms. 

In the message level transform you can add a code block and save a value of PV1:2 in a variable. Then you can pass that variable to a sub-transform (segment level transform) as Auxiliary value.  

Then in your OBX transform, you can use that aux variable as a condition to "if" or "switch" statement.

Let me know how it went. :)

Hi Brett, I edited .code-workspace by replacing "isfs-readonly" with "isfs" and it worked. Thank you!

Hi Julian, no I don't get this option
