How to run fee invoice posting for all classes

To run fee invoice posting please go to Fee invoice -> Fee Invoice Posting -> Create New. Keep classes as NA if you want to run for all classes. 

Once created, you can see in the Generate Fee Invoice screen that invoices would be created with DRAFT status. You can check and verify if everything is ok. If you are ok with it, simply go back to the Fee Invoice Posting screen and edit the entry and set POSTED = YES and save. This will queue the task for you and post all the invoices one by one. You can see the running status in the report. 

Once completed, all invoices would be Changed from DRAFT to POSTED.
