Note: Row level locking will affect the SAP performance.

1. Go to SE11

2. Give the lock object name [EZJKAK](lock object name start with EZ) and click 'Create' Button.

3. Enter the short description,Table name[jkak], lock mode and key fields which is used to lock the entry.

4. Save and activate, it will generate 2 FM.

Ex:

DEQUEUE_EZJKAK Release lock on object EZJKAK

ENQUEUE_EZJKAK Request lock for object EZJKAK

In your program,

1. First loop the table.

2. call the FM 'ENQUEUE_EZJKAK' to lock.

3. Update the dB.

4. Release the lock using DEQUEUE_EZJKAK.

endloop.

DEQUEUE_ALL this FM will release all the lock.
