Item arrival is used for registeration of items/PO
A purchase Order has following states
- PO Creation
- Conformation
- registration of item and picking list
- Packing slip/product receipt
- Invoicing of PO
step#3 registration of items can be done from two locations(screens)
- Either you can do this from PO directly
- or you have to choice to do it with Item Arrival registration
you might be thinking if the process can be done from PO, what was the need to provide a separate journal from items arrival registration?
It's mainly for sake of segregation of duties, so that warehouse people don't bother to have access to PO. instead they can just do their work within warehouse/inventory management
