Access used up to now is no longer valid and will be deleted

What causes this issue?

You are editing a focus master record whose focus access (internal
reference) to an iPPE product model with material, plant and usage is
no longer valid. This causes a conflict when the dependent information
is to be read.

System Response

The system deletes this focus access in the current focus master record
because this situation is not intended to arise.

How to fix this error?

When the old infomation has been reset, you can create a new focus
access for the iPPE product model with a material, plant and usage.
Contact your system administrator, because this combination could only
be caused by an administrator accessing the database layer.

Procedure for System Administrators

Ensure that when the filter table is changed manually in the database,
the dependent data in the focus table is also adjusted.
