Replication of BP in custom role from CRM to ECC (FI-CA)

Hi Experts,

I have created a custom BP role in CRM by copying the standard BP role CRM000. Similarly I have created a custom role with the same name in ECC by copying standard role MKK. The required middleware configurations have been done.

When I try to replicate a BP with a custom role, then BP is getting replicated (entries in table BUT000). But when I try to open a BP using T code FPP3, it is giving the error  - BP does not exist in role MKK.

But when I replicate a BP created with standard role CRM000, it is getting replicated in ECC with MKK role.

Are there any additional configurations or enhancements that needs to be done for replicating BP in custom role?

Thanks in advance,

Anwesha
