Partner Replication from CRM to ECC

Hi Experts,

There is a issue related to the partner replication from CRM to ECC in a Iobject.

In a standard way manually if we add or change a particular partner in CRM , it gets replicated to ECC successfully.

But we have developed a custom code to change or add a partner to the Iobject using the FM COM_IL_PRDBP_API_MAINTAIN, but using the custom

code, the partner is not getting replicated to ECC.

I have checked by taking  a trace  if the same FM COM_IL_PRDBP_API_MAINTAIN is being used to maintain the partners even if we try to do it

manually.And  the same FM is getting called.

What could be wrong about the replication through custom code ?? Any suggestions...?

Please help.

Regards,

Jojy.
