How to restrict the flow of credit card information from ECC to CRM

All,

I need your help in finding answers to the situation wherein we would like to stop the credit card related information replication from ECC to CRM.

In ECC the required configuration for card type, card category exist but in CRM since we are not maintaining credit cards we do not have the required configuration.

But when I am making a change in the payment card record in ECC, the delta is going to CRM and is failing with a error Bdoc.

The error bdocs are building up.

Any ideas as to if there is a way to restrict the delta replication of credit card related changes from ECC to CRM.

Is there any relevant adapter object for the same to put filters?

Thanks
