Release Info cube to OLTP

Hi,

I am releasing a key figure from info cube to the OLTP syetm (APO to ECC 6.0) as a PIR quantities. The program is executed by process chain in RSPC transaction. The process is executed without any error messages. When I check the planned Independent requirements in ECC system. There is no PIR created.

I have checked the RFC connection between the ECC and APO systems and found the connection is OK. How can I further troubleshoot this issue.

thanks and regards
