Change the Source of Supply
You can change the source of supply for an order in the product view. If you change the source of supply for an order, the system deletes the order in the following cases and then creates a new order, which has a new order number, with the desired source of supply:
· You substitute a source of supply for external procurement with a source of supply for in-house production, or vice versa.
· You substitute an external procurement source of supply with an external procurement source of supply with a different procurement type; for example, you substitute normal external procurement with subcontracting.
· In the case of external procurement, you substitute the source location of the type supplier with a source location of the type production plant, or vice versa.
·
You change the production
location for an in-house production order. This case is relevant for
production in another
location. You can only change
the production location of an in-house production order if a source of supply
exists for the combination of planning location and new production
location.
In all other cases the original order is retained with its original order number.
If the in-house production source of supply (PPM, iPPE access object, PP/DS runtime object) is switched, the system reexplodes an in-house production order, provided the status of the order permits this. For example, if in the case of an in-house production order you change the production process model (PPM) from PPM1 to PPM2, the system reexplodes the in-house production order using the plan for PPM2.

For a reexplosion, the order may not have any of the following statuses:
Input firmed
Date firmed
Released
Started
Partially confirmed
Finally confirmed
