Existing status information from QM will be deleted

What causes this issue?

The current program must make new entries in Table &v1& . The database
table check has found that data already exists in the QM objects number
range.
The data is located in tables JSTO, JEST, ONR00 and it fulfills the
selection criterion OBJNR = 'QL*'.
Only data from the QM area should be located in this area.
One of the following reasons may be responsible for data being located
in the QM objects number range:
an earlier program run was aborted and some of the data was already
generated
customer data is located in the above referenced area.
The data may cause database errors to occur during this program run or
during the subsequent operation of the QM module.

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?

The corrective action depends on the cause of the error:
if an earlier program run was aborted and <ZH>only</> QM data is
located in the above referenced area, no further action is necessary.
if customer data is located in this area, clear the incorrect data as
follows:
Check the environment.
If necessary, restore the backup data for tables JSTO, JEST, ONR00 and
QALS.
Remove the customer data before you execute the program.
