Block for Payment card data transfer from ECC to CRM

Hi all,

Greetings,

We are working on the customer master download from ECC to CRM , the typical requirement  is that PAYMENT CARD related data need not to be  transferred to CRM, it should be filtered out . 

Is there STANDARD  way out  there on either side CRM or ECC to filter out or  to block the payment card data ?

We want to avoid any kind of development on either side ECC or CRM.

Have anyone has come across this type requirement or do have experience against this requirement?

Kindly share the details ,

Thanks with regards,

Arun
