Activation difficulties due to open V3 updates --> Long text

What causes this issue?

Open, unprocessed V3 posting entries still exist. The updating of one
or more information structures has been deactivated and is to be set to
V3 posting. Information structure &V2& belongs to application &V1&.
After activation (change from no updating to V3 posting), the open
posting entries are updated in the next collective run. As a result,
documents that were created or changed before the time of activation
are updated.

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

Caution: In the transport of the activation, the udating is only
activated in the target system if no open posting entries exist in the
target system. The transport (import and method execution) should only
be carried out in a period in which no posting is taking place and
after V3 posting (colllective run) has been carried out.

System Response

How to fix this error?

Start the <DS:TRAN.MC3V>Collective update (V3)</> before changing the
update type from or to V3 posting and before the transport (import and
method execution) of such a change so that the open V3 entries are
posted.
You can check open V3 posting entries in the <DS:TRAN.SM13>Update
overview</> (V3 update modules with category collective run and status
INIT) and delete these if necessary.
