Changing type of replicationobject from simple bulk to simple intelligent possible?

Hello Together,

We don't want to replicate the relationship category BUR001 from CRM to R/3 anymore.

But the replication object Bupa_Rel (as Bupa_Main) is defined as type simple bulk.

I can't find a function to change that type??

Or has someone another idea  how to prevent the replication of this relationship while replicate the bp-master data?

Thanks a lot for support:-)

Kind regards

Ursula
