Steps to reproduce:
- Create one (or several) expense lines
- Submit them to the manager (create the expense sheet)
- Approve the sheet and post the entries
- Delete the created and posted sheet
Bug:
- The expense is deleted but the accounting entries are still in the database
- The expense lines are in "To submit" and you can submit to manager again and
generate a new report and therefore new accounting entries...
Fix:
It is not allowed to delete posted expense.
