Restricting Usage of Open FI Exit 1650 to Company Codes

Hi Experts,

We are thinking of using the exit 1650 for one of our client requirements. The client has presence in many countries. But this enhancement is to be done only for company codes in 1 country and other country company codes should see the FBL*N in standard way.

Is this possible and if yes, how this can be done?

Thanks and Regards,
