SFC number uniqueness for SAP ME objects


In the base SAP ME an SFC number must be unique across the application. This may be the limitation if there are several sites running on the same SAP ME instance and having the same SFC numbers.

I cannot find any documentation describing what numbers/IDs must be unique within a site, what must be unique within the application, are there any system rules that affect uniqueness of these numbers.

What is the scope for each of following the serial numbers:


- Shop Order

- Process Lot


- Container

- Incident

- Slot

- Inventory

- Customer Order

- Component Hold

- ECO Number

- Vertical Reference Number

- Horisontal Reference Number

- Test Plan configuration

- CNC Program ID

- Batch Number

Historically base code generates SFCs unique in the application scope. There is one more category that is also unqiue in the app scope: SO Batch number.

As far as I see for all other objects the scope is SITE by default.

There are some internal use cases, like create trackable SFC, when internally SFCs are generated in the SITE scope.
