BAPI_CASESERVICE_CREATEMULT not triggering service rule

Hi all,

I have a question on the bapi BAPI_CASESERVICE_CREATEMULT.

We called this bapi in a program to create a service in outpatient case. We have a service rule type ZS1 which will remove the billable indicator for the service created based on certain conditions.

But when i execute the program, the service rule is not being triggered. I did a break-point in the service rule and execute the program and confirmed that the service rule is not being called.

I read up the documentation, and the only information given is for the internal table  caseservice_cdata, the ruletype given must be a valid one with BAPI as one of the Uses for Rule Types. The call up point is also correctly set. If i create the service directly in the case movement, the service rule is working perfectly.

So other than passing in the Rule type in the internal table  caseservice_cdata, what else do i need to do in order for the bapi to trigger the service rule?

Thanks!
