Choosing and Displaying Lock Entries (SAP Library - The SAP Lock Concept (BC-CST-EQ))

Choosing and Displaying Lock Entries

You can display lock entries according to the following criteria (see also Functions of the SAP Lock Concept):

Table in which rows are locked
Lock entry argument
Client
User who set the lock

The client and your user are added automatically. If you want to display the locks of a different user or client, you must overwrite the relevant field. if you leave the field blank or enter a *, the data is selected according to all possible entries.

The lock entry display contains the following information:

The Man column contains the client in which a lock entry was created.

The User column contains the user who set the lock (that is, the user who executed the ABAP program that created the lock).

The Time column shows when the logical unit of work (LUW) was started, in which the lock entry was generated.

In the Shared column, you can see whether a lock object is being used by several users. In this case, the column contains an X. Otherwise, it is empty.

If a lock object has more than one shared lock, several users can lock the same data at the same time. See also Lock Mode in the ABAP Dictionary documentation.

The Table column contains the tables in which rows are locked.

In the Lock argument column, you can see the argument (key field) of the lock entry.

This corresponds to the entries in the lock table.

The lock entries are shown in different colors:

Blue means that the locks have already been transferred to the update task(see also The Owner Concept), with the result that the backup flag is set. These locks are also rewritten to the lock table when the enqueue server is restarted.

Black means that the lock (still) belongs to the dialog owner. The backup flag is not set.

By choosing Edit ® Sort by, you can display the locks according to user, time, table, or host system (host).

By double-clicking a lock entry, you can display detailed information, including the host name and number of the SAP System in which the lock was generated.
