Internal vendors PS 9.1

 Hi there,        We have an internal vendor in our system where we process transactions (i.e vouchers) however we are not suppose to cut a check for this vendor. Is there a way to process a voucher and not cut a check on the vendor level? I know you can do this on the voucher level but I am looking if we can set this on the vendor level? Please advise. Your input is much appreciated.

Thank you,

Dante
