How to put the results of a singlecall e.g. jdbc call into the "CA" segment in the B1iMessage?

Hi,

How to put the results of a singlecall e.g. jdbc call  into the "CA" segment in the B1iMessage?

I can access jdbc:ResultSet/jdbc:Row/, but I want to put the results in the outbound message, something like "KeyExpansion", as a result, the retrieve information can be added in the section "SA" or "CA" in the message.

Best Regards

Jim Jin
