Hi,

Use enqueue FM before updating the table and After updation use dequeue FM.

DO.

Use ENQUEUE_E_TABLE FM to lock the table

IF sy-subrc = 0.

EXIT.

ENDIF.

ENDDO.

UPDATE statement.

IF sy-subrc <> 0.

Error Handling.

ENDIF.

Use DEQUEUE_E_TABLE FM to unlock the table for others to modify.

Do enddo is used to ensure that there are no locks apart from yours on the table before you update it.

Thanks,

Kartavya
