LOOP IN BPM

HI FOLKS,

I HAVE THE FOLLOWING SCENARIO:

RFC->XI->WEBSERVICE

THIS SCENARIO WORKS FINE BUT I NEED TO MAKE SOME CHANGES.

RFC PASS A STATUS "EXEC" FOR XI AND XI CALL A FUNCTION IN WEBSERVICE. WEBSERVICE RETURNS A XML WITH SOME SERVICE ORDER AND XI NEED TO CALL A RFC FOR EACH ORDER. IF WEBSERVICE RETURN 5 ORDER, XI WILL CALL RFC 5 TIMES.

HOW CAN I DO THIS?

DO I NEED A BPM?

WHICH ARE THE STEPS?

THANKS,
