Debug CIF - ECC inbound - User exit CIFORD03 - Planned order to process ord

Hi

While Converting planned orders to process orders from APO to ECC, queues are not getting stop in Inbound ECC.. even after setting CIF user as dialog user and maintaining both CIF user and my user ids in /sapapo/c4 to block queues. maintained the same in ECC CIFGPARAMV table. Outbound queues are stopping in APO, but not able to debug APO outbound queues...

I want to debug user exit CIFORD03 (EXIT_SAPLCORD_005 ) in ECC . Please reply.

Thanks
