Origins and destinations

Parts can have multiple origins and multiple destinations. The principle of the different origins and destinations of parts is interwoven into Isah.

Origins

Parts always have an origin. Origins are locations from which parts are available. Possible origins in Isah are:

• Purchase orders
• Production orders
• Stock

On 'origin locations', you can specify the destinations of the parts. This process is called 'assignment'. Assignments are always expressed in quantities (values such as length, width, and height are copied straight from the origin location).

An origin can have more than one destination. For instance, some of the parts produced under a particular production order may be used for a sales order, while other parts may be added to the stock.

Purchase order lines are an exception in this respect, as they can only have one destination.

Destinations

Parts always have a destination, i.e. a location where there is a demand for the parts. Possible destinations in Isah are:

• Sales orders
• Production orders
• Stock

On 'destination locations', you can specify the origins of the parts required. This process is called 'specification'. Specifications are always expressed in quantities (values such as length, width, and height are copied from the destination location).

A destination can have more than one origin. For instance, some of the parts sold under a particular order may come from production, some from stock, and some may have been purchased.

Stock as a balancing item

If more parts have been produced under a production order than are required at the destination, the remainder is automatically assigned to the stock. The stock is therefore the item that balances the books, or the 'balancing item'.
