When to use logical database locking?

[gopalkrishna_baliga]

Hi Experts,

I have a custom table in one SAP R/3 system A. I am updating this table from another SAP System B from two different programs ( one an user exit and another one a function module). Suppose user exit code is updating the table and at the same time the Function module also tries to update the same table. I think SAP automatically takes care of locking the table and unlocking it. I hope we don't have to explicitly code it right?

Then why SAP has provided ENQUEUE and DEQUEUE function modules? When exactly do we need to use them?

Please help.

Thanks

Hi,

SAP will not automatically takes care of locking the table and unlocking it. you need to explicitely create ENQUEUE and DEQUEUE function modules.
