What is required:
- Ability to cancel a project invoice proposal in F&O which also cancel the equivalent draft invoice in CE.

Problem statement:
- Currently in the CE-FO integrated projects operations scenario, when a draft invoice is confirmed in CE and resulted in a project invoice proposal auto-created in F&O.
- There is no ability to cancel a project invoice proposal in F&O for an incorrect invoice.
- You are required to proceed to posting the incorrect invoice in F&O and perform a corrective invoice from CE.
- This causes (1) additional invoice number/credit note number being consumed from the number sequence range, (2) additional work created to knowingly post an incorrect invoice, raise another CN to reverse, and raise a 'correct' invoice.
