Source Code
Description
The function codes ENQUEUE and DEQUEUE of the GUI status can be used to lock and unlock the specified fields of the table SFLIGHT. This is done using the lock object EDEMOFLHT is used using the corresponding function modules ENQUEUE_EDEMOFLHT and DEQUEUE_EDEMOFLHT.
Furthermore, the function code SELECT enables the specified fields to be accessed and the function code SM12 calls the transaction SM12 to display the lock entries in the central lock table.
Once the data records have been locked by a user, no other user can lock the same records again. All users can, however, access the locked data records using statements, assuming the program did not already check the locks using ENQUEUE_EDEMOFLHT.
