What selection variant to distinguish "Create DME" and "Remit Payment"?

Hi all,

Program RFFOUS_T is used to run the Create DME and Remit Payment to Bank. As I know, one would need to run Create DME first before running Remit Payment to Bank, right? So what is the difference between these ? I mean it looks weird running RFFOUS_T and then run the RFFOUS_T again? Is it there is specific fields to enter in RFFOUS_T for Create DME and another different set of fields in RFFOUS_T or Remit Payment to Banks?

TQ.
