All product versions use an easy to track, back to back, order numbering system where  production orders and purchase orders are related to the original sales order reference.

Sales Order Reference:

The Sales Order Reference is a customer facing number. When a sales order is saved, a Sales Order Reference will be displayed, with the following format:

Prefix  + SalesOrderNumber + suffix

A Sales Order may have one or more orderlines, which represent each item in the order. This representation shows the relationship between the Sales Order Reference, WorkOrderID and JobNos.

Sales Order Reference	Line No	JobNo
11-101	11-101W1	11-101W1
	11-101W2	11-101W2
	11-101W3	11-101W3
	“”	“”
	“”	“”

If the JobNo has child items (i.e. it is an assembly), additional JobNos are created, with the suffix C1, C2 and so on. 

Special Cases: Stock Orders

A stock JobNo will have a different numbering sequence, and usually has a suffix "S"

Special Cases: Add to Assembly Order

If a new child item is added to a current assembly work order from Assembly Orders Status management, then a new JobNo is created, usually with suffix "a"
