to see whether they contain entries. Even if a logging table contains no
entries, SAP Landscape Transformation Replication Server notes that the
logging tables have been checked.
This information about the logging tables being checked could not be
retrieved. The reason for this could be that the table has just switched
from the initial load phase to the replication process.

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