Diagnosis
No lock can be set for &V1&.
When data conversion is being performed in an update run, no other progr
ams may access the data for &V1&. This is to ensure data integrity. Forthis reason, the data for &V1& must be protected by a lock before dataconversion is performed in an update run.

System Response
The data conversion is terminated. Data is neither changed nor saved.

Procedure
Ensure that no other users in the system have access to the master dataduring data conversion. Ensure also that no transport requests are impor
ted into the system during data conversion.
Then execute the data conversion again.

Procedure for System Administration
Whenever you perform a data conversion, we recommend using the system ex
clusively for the data conversion, which you can ensure by temporarilyblocking other users, for example.
