Idoc receiver PI 7.3 -sender port(populated as 'tRFC') in Control Record

Hi,

I am working on a AAE Idoc receiver scenario in PI 7.3.When I uncheck the "Apply control records from payload",it should take values of sender and receiver(in control record) from runtime.As I run the interface,all values are getting populated correctly in control record,except the sender port(which is populated as 'tRFC'),and it should actually be the PI port configured.

Please let me know if anyone has any idea about this scenario.

Regards,
