A switchover to the follow-up product has priority over a switchover to a replacement product. This can lead to the following when the time periods overlap:

When posting a switchover to a follow-up product, the posting time is relevant. The switchover to a follow-up product that is posted first has priority over a switchover that is imported later. As soon as SAP F&R has posted a switchover to a follow-up product, it can no longer transfer switchovers for the same original product.

When posting a switchover to a replacement product, the switchover time is relevant. The switchover to a replacement product with a later switchover time has priority over a switchover to a replacement product with an earlier switchover time.

If the time periods overlap, the system shortens a switchover information that lies further in the past and posts in addition the newer switchover to the replacement product.

Following a switchover to a follow-up product, the original product cannot appear as the original product of a substitute product in switchover information; an exception is the case where the system subsequently posts the switchover to the follow-up product (because SAP F&R – for example, due to technical problems with the data transfer – could only import the data with a delay). Here, some items of existing switchovers to the replacement product may be deleted (however, not with the follow-up product).

Inserting a new switchover to the follow-up product before an existing switchover may not change the lock situation of the location products of the existing switchover.

A location product can only appear in one switchover at any time (as an original or substitution product).

It shortens the merge period and forces a switch back if one does not yet exist.

On import of a switchover to the follow-up product, the system deletes items from an existing switchover to the replacement product or also the complete switchover.
