Want to differ the execution of one stage of request set until one of the child request of previous

Hi,

As a part of customization in accounts payable, we have designed a request set which has following major stages

1) Stage 10 --> It has a "Submit payment batch program" with executable name as APXSPBST. This is a java concurrent seeded program which gives call to "Payment Process Manager" program. Submit Payment Batch Program does not wait for its child program to complete instead it will submit the child program and completes into normal

2) Stage 20 :--> A custom program which derives the check run name from argument text of payment format program. Hence, "Payment Process Manager" programs must completed normal before the execution of custom program in stage 20.
