If a conversion terminates, the system retains the lock entry that is set at the beginning of the conversion process for the table. For more information, see Conversion Process . You cannot edit the table with the ABAP Dictionary maintenance tools (transaction SE11).
If a table conversion terminates, you must correct it. Otherwise, applications that access this table are not able to read any data correctly. These applications function improperly or fail to run.
The maintenance screen for the table appears in display mode.
The screen for the database utility appears.
The next screen lists the conversion steps that were processed correctly. It also shows the status of the tables involved in the conversion (the table with the old structure, QCM table and the table with the new structure). It can also be used to display the existing system log entries or short dumps.
You can find out the exact cause of the termination from the object log. If the object log does not provide any information about the error, you have to analyze the system log or the short dumps.
The conversion can be continued only if the error causing the termination has been corrected.
The system now tries to continue the conversion from the termination point.
Besides Continue adjustment, there is also the Unlock table option This option deletes only the lock entry that exists for the table. Do not choose Unlock table for a terminated conversion if the data exists only in the temporary table, that is, the conversion that was terminated after step 2 is completed and before step 4 is completed.
