Description
RDDTLOCK is used to adjust the lock key table in conjunction with theobject name extension for Release 4.0. The program can be executed asoften as required in an SAP System with extended object names (restartcapability).
If the program is started in an SAP System that has not yet beensupplied with extended object names, or in which tables with extendeddomains have not yet been converted, execution is prevented by internalchecks. If the program is executed in such a system, this may result inthe contents of the lock key table being lost completely.
When an SAP System is upgraded from a Release prior to 4.0 to Release4.0 or later, this adjustment report must be run once successfully(without errors). If it is not executed or does not run correctly,there is a risk that problems will occur in the lock management ofobjects in repairs or corrections, therefore impairing regulateddevelopment coordination.
Example
Objects or related sub-objects that are already locked in repairs orcorrections can be included in other repairs or corrections. Thisprevents the original repairs or corrections from being released.
To adjust the lock key table, the existing entries are divided into thefollowing groups, which are treated differently:

• Lock keys with old syntax (old name lengths of the objects)


• Lock keys with new syntax (new name lengths, occur particularly when
the report is restarted)

• Other entries (incorrect - are marked for deletion, since they are not
currently locking any objects)
The lock key entries from the first two groups are processed asfollows:

• The transport objects are determined for lock keys with the old syntax,
and the appropriate lock keys then found with the new syntax.
If conversion is successful, the new lock keys are marked for insertioninto the lock key table. The corresponding lock keys with the oldsyntax are marked for deletion from the lock key table.
Lock keys with the old syntax for which no transport objects can bedetermined - these lock keys are also marked for deletion, since theyare no longer locking any objects.
Lock keys for transport objects that can no longer be locked are alsomarked for deletion from the lock key table.

• Lock keys that already exist with the new syntax remain unchanged.

After all entries in the original lock key table have been processed inthis way, the database actions only noted up till now are actuallyperformed:

• Transferring the converted lock keys to the lock key table


• Deleting the old and the incorrect lock key entries

The incorrect entries that were deleted are then listed.

Precondition
The SAP System must know the new name lengths of the transport objects.The tables with extended domains have to be converted.
These system requirements are checked in the report; if they are notmet, the report cannot be executed.

Output
The report output is shown with the log interface, which allows variousexpansion levels to be displayed.
