Payments for Project invoices by another person (cash mgr) on behalf of Project Owning OU?

Hi,

We have a requirement to create a Project in X entity.

1. Allocate non-GL integrated cost budgtes to the project, baseline.

2. Then perform POs from X entity, with bill to as 'Y' entity and ship to as 'X' entity.

3. Now, receive PO in 'X' entity.

4. Perform AP Match from 'X' entity.

5. Send above matched invoice to 'Cash Mgr.' (Outside person email address) for payments by him on behalf of 'X' and 'Y'.

6. Cash Mgr (Outside person email address) would advise 'X' upon paid above invoice.

7. The Invoice has to be marked as “paid” in project module only.

8. Then, we wish to close the project when all such invoices are closed (“paid”).
