SoD between AP Payment Supervisor and AP Manager

hello,

We would like the AP payment supervisor to submit payment process requests, review instalments and validation (if necessary) but we do not want the AP payment supervisor to be able to 'Resume Payment Process' which is basically sending it off for payment file build and transmission. We only want the AP manager to be able to do this.

I have tried removing each functional security policy which falls under the 'Disbursement Process Management' role but I can't seem to restrict this final step.

Please let me know if any one else has faced this issue?

Many thanks,
