SAP BP and CA master data update

Hi,

I have a question on SAP BP and CA master data update.

When i update a address of the business partner in FPP2 for the MKK role it is automatically updating the changes in Contract account.

To mention the field, Jurisdiction code gets updated at contract account level once i make the changes in BP address, Is there a way that i can restrict this ?

Thanks,

Raj.
