Thanks. But they do not help.  I see this code "D55^Z73^7" [ context.PIDAssigningAuthorityID.  How would I know what the [ means?

..CurrentDateTime("%K(-4)%q") works to produce the current date/time in ET. However, I'm not sure if this intersystems function allows for variables ..CurrentDateTime("%K(tDstOffSet)%q"). What is returned is the UTC time which is the default for this %K format.

Was there ever a provided solution? I created a pipe delimited charge RecordMap.  I need my business rule to not send when charge quantity in < 1.  Is there a specific Rule Assist Class for BP?  What do I choose for Message Class in the when statement rules?  In the when condition, how do I reference the fields in the RecordMap
