Deleting members will change the chain interpretation; check entries

What causes this issue?

You have deleted parts of the supersession chain. If you delete parts
of the chain, the chain will be interpreted differently as a result.

How can this happen?

Your supersession chain is as follows:
SUS-01 --> SUS-02 --> SUS-03 < --> SUS-04
If you delete a material in this chain, the chain is then interpreted
as follows:
SUS-01 --> SUS-02 <--> SUS-04
It is possible that the interdependencies are no longer represented
correctly in this new chain, because material SUS-04 is not
interchangeable with material SUS-02.

System Response

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

How to fix this error?

Make sure that the supersession chain is complete.
