Submission of Payslip by Account Manager

Hello All,

We have implemented version 14 of ERPnext, and we want a situation where only Account Manager can submit the Salary Slip to hit the journal Entry . We have tried permissions and all, but the account manager is still not able to view the Payslip from as we keep getting error. So is it possible that the Account Manager role is overriding any other role assigned to the account officer.
