Currently any user with Manage Projects Access has the ability to add or remove split payments in the edit payment status screen. We are seeing project managers and admins removing or adding split payments without the accountant's knowledge. This has resulted in us overpaying/underpaying subcontractors.
The only users we would want to have this ability would be out project accountants. From Swinerton's process, only the Project Accountants have authorize payment access so ideally, the ability to add/remove split pays would tie to the Authorizer access security role or a standalone permission.
