You would like to migrate Sales Orders which are completed.
SAP Business ByDesign
The migration of completed Sales Orders is not supported.
You can migrate completely open Sales Orders. A completely open sales order is a document defining that all items are not yet delivered and invoiced, not even partially. In this case, the complete sales order is migrated.
In the case of migration of Partially Delivered and Invoiced Sales Orders, you must distinguish between the following cases:
Sell From Stock (SFS) — Examples:
Item 10 is fully delivered and invoiced and item 20 is not delivered and not invoiced. Only item 20 is migrated.
In item 10, 100 pieces are ordered, 40 delivered, 40 invoiced. Only 60 pieces of item 10 are migrated.
In item 10, 100 pieces are ordered, 60 delivered, 30 invoiced. 30 pieces in old system are invoiced, then 40 pieces of item 10 are migrated.
Sell Standardized Services (SSS) — Examples:
Item 10 is fully invoiced and item 20 is not invoiced. Only item 20 is migrated.
In item 10, 100 pieces are ordered, 30 invoiced. Only 70 pieces of item 10 are migrated.
