Hello,
Try with ABAP program . Read the file and run the process chain through function module.
Function module to run the process chain:
CALL FUNCTION 'RSPC_CHAIN_START_SYNCHRONOUS'
EXPORTING
i_chain = p_chain
IMPORTING
e_logid = e_logid
EXCEPTIONS
failed = 1.
Hopefully it will works for you.
Saleem.
