our requirement from our customer is that in the invoices created by Professional Services' project, must have a different payment terms, for example:
- Workpackage 1 Fixed price billing: installement payment terms
- Workpackage 2 Periodic services: 30 days invoice date
The only change to the payment conditions can be made only on order created automatically by the project and only at the level of the header. We need to change it at positions level.
The next step (release customer billing request) create a request that's not editable
Any suggest will be appreciated
