If you need to clean up your production orders and their related journals as well as related info, then you’ll want to look at the clean up functionality for production orders. 

This will delete ended production orders (ProdTable) ended on or before the date you select with business logic and alerts disabled. Next, it will delete from the following:

Production BOM (ProdBOM)
Production Route (ProdRoute)
Route Jobs (ProdRouteJob)
Capactity Reservations (wrkCtrCapRes)
Calculations (prodCalcTrans)
Production Journal Table (prodJournalTable)
BOM journal Transactions (prodJournalBOM)
Production Journal Transactions (prodJournalProd)
Routing journal transactions (prodJournalRoute)

This will remove any production order and its related records but it leaves all inventory and financial tracking in place.

Go to “Production control”>>”Periodic Tasks”>>”Clean up”>>”Production orders cleanup” then choose the date on or before which ended orders will be deleted
