What causes this issue?

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

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 another BW system even if it already
appears there as being active.
