The “Subcontract Purchase Invoice Process” page should be a part of the subcontract menu. Otherwise, nobody sees that it’s actually a part of the process. The documentation also needs to be updated to reflect that it's a required part of the process.
The Purchase Invoice Process Page/List will apparently keep all requests no matter if they have been created into purchase invoices or not. That’s fine, but there needs to be some type of status so you can sort through all of them. Such as Purchase Invoice Generated, Error, Approved - Purchase Invoice Pending. But I’m not sure the entries shouldn’t disappear from this page after they have been created?
The process would be easier if explained and simplified.
