How to fix this error?

Now choose the maintenance screen of the DataSource. After that, the
status display (traffic light) jumps from red to yellow.

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

Please make note of the following before you transport the changed
structure &V1& into another system:
Run the transport when the target system is not being booked. Otherwise
you will need to initialize it because documents are lost during this
time.
None of the clients in the target system in the V3 update for the
application &V2& should contain data. If you are unsure, start the V3
update of the application &V2& in all clients.
If there is still data in the central delta management of the target
system, it must be retrieved by BW before the transport takes place.
If you have already reconstructed within this target system, it may be
that the data still exists in the reconstruction tables. After the
transport, you can no longer transfer these entries into BW. You must
delete the contents of the reconstruction tables of the application
&V2& in the target system and run another reconstruction if need be.
If there is an update log in the target system, you cannot read the log
data of the application &V2& after the transport has been run. You can
only read it again once data is booked and the last log entry
overwritten.
Use the report <DS>RMCSBWCC</> to display a log for the changed extract
structure in the target system, to see if any of the above problems
exist. An additional switch deletes all update logs for the application
of the selected extractor.
Please also note that you must reactivate the transfer structures when
you change the extract structure after replicating a DataSource.
