How to stop the replication of contact person from ECC to CRM

Hello,

I am facing one issue. I have download Customer (one particular group) from ECC. I have configure every thing and everything looks good and its working in Production. Now all the customer assigned to that group are replicated to CRM.

But in delta download, contact persons are also coming with a relation ship has contact person. But we don;t require these contact persons as we separately maintained the contact person.

For your reference, while doing the initial download I have downloaded the customizing objects,

DNL_CUST_TSAB

DNL_CUST_TPFK

COSTOMER_MAIN

But I didn't downloaded the relationship object CUSTOMER_REL. But still relationship are coming.

Is there any way to to stop the replication of relationship coming from ECC.

Thank you all in advance.

Regards
