hi Gurus,

i have a Remote enabled Function module which updates a Zee table. This function module is called by many systems(more than 15 systems) at the same time.

My problem is, how do i maintain consistency of the data being updated?

is Lock Tables concept going to help me in any way. please suggest a possible solution.

you need to create a lock object and handle.. them before updating the data...

* Lock the table
CALL FUNCTION 'ENQUEUE_E_TABLE'
EXPORTING
mode_rstable = 'E'
tabname = p_table
EXCEPTIONS
foreign_lock = 1
system_failure = 2
OTHERS = 3.
 
IF sy-subrc = 0.
 
* Modify the database table with these changes
MODIFY (p_table) FROM TABLE <dyn_tab_temp>.
 
REFRESH <dyn_tab_temp>.
 
* Unlock the table
CALL FUNCTION 'DEQUEUE_E_TABLE'
EXPORTING
mode_rstable = 'E'
tabname = p_table.
