What causes this issue?

This system acts as the source system for replicating data into a BW
system. The connection was set, for example, based on an upgrade to an
inactive status. This change in status is not automatically forwarded
to the BW system. Therefore, the source system still appears in the BW
system as being active.

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?

Activate the source system in BW, even if it already appears there as
being active.
