Testcase to check if allocations with missing accounting despite posting are correctly reposted by the schedule process.
Open Allocation Header, select one for testing (you can also select several, for payment, invoice etc., BUT make sure they are created on the day before testing!)
Delete the accounting for your allocation header(s) in the database
Run the new schedule process for Documents_FactAcct_Creation_For_Posted (change the cron pattern and restart the server)
Note: The schedule process is set to repost only data created the day before, and runs usually every night at 1:30 AM. If you want to have older data reposted, you have to change the created date for those in db first!
