How To Fix SFW308 - Possible data loss during package assignment to deactivated switch

SAP Error Message - Details

• Message type: E = Error

• Message class: SFW - Messages for Switch Framework

• Message number: 308

• Message text: Possible data loss during package assignment to deactivated switch

What causes this issue?

A package that contains Append structures is to be assigned to a switch
that is probably deactivated after activation. 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.
If, in this case, you are dealing with a database table or if the
structure is part of the definition of a database table, this will lead
to loss of data.

How to fix this error?

Check whether the deactivation process can have negative consequences.
If this is the case, you have the following options:
Ensure that the switch is activated before you assign the package.
Change the package assignment of the affected Append structures. Assign
an activated or non-activated package to the structures in question.

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