Hi ,
at end of your process chain add program step.
add program inside it..
and write code to call below FM:
CALL FUNCTION 'RSPC_API_CHAIN_START' "
EXPORTING
i_chain = " rspc_chain Enter Process Chain
IMPORTING
e_logid = " rspc_logid Log-ID of a Process Chain Run
.
this will keep your process chain calling in n loop.
