Restrict access to process payment for specific company code in F110

Hey All,

We want to restrict users to process payment run only for specific company code. For eg: if the user belongs to US company code 1000, he/she should be only able to execute payments for company code 1000 and not for company code say 2000: Mexico.

Also, the user belonging to company code 1000 should only be able to download payment media file relating to company code 1000.

I hope this does not require a ZF110!
