to the switch contains an Append structure. In this case, the Append
structure will be deactivated during activation so that the fields
contained in it will be removed from the appending structure.

How to fix this error?

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

Check whether the deactivation process can have negative consequences.
If this is the case, you have the following options:
Before you start the decoupling action, assign the switch to another
activated busines function and activate the change. Afterwards, you can
safely proceed with the decoupling.
Change the package assignment of the affected Append structures. Assign
an activated or non-activated package to the structures in question.
