Hello,

Transaction SE11 -> Lock object

Once you activate it, your ENQUEUE and DEQUEUE modules will be generated.

First you have to create a lock object in SE11, once this lock objects are created you will be automatically generated with FUNCTION MODULES based on below logic:

1. ENQUEUE_<Lockobject name> = To lock the table to be processed

2. DEQUEUE_<Lockobject name>. To release the lock

Once you create a lock object 2 function module will be created automatically with name "ENQUEUE_<name of lock object> and "DEQUEUE_<name of the lock object".

The naming convention for lock object is "EZ*" or "EY*".

During creation of lock object, you have to provide the table name which you want to enqueue, and you have to specify the field list as "Lock Parameter". Generally key fields of the header table is used as the "Lock parameter". Once the lock parameter are added, the parameters are available as "Importing parameter" in the enqueue function module.

Thanks,

Hi,

Create lock object in se11, it should start with EZ or EY, after creating you have to provide 'table name' and 'lock mode', then in another tab you have to give the fields list as lock parameter, by default it will take primary key of table as lock parameter. once your creation, activate it. after activating automatically two function modules will be generated i.e 'ENQUEUE' and 'DEQUEUE' function modules.

we can check function modules -> menu -> goto -> lock modules, you can see function module here.

for example if your creating lock object by this name EZ_LOCK_TABLE,

function modules are generated like this ENQUEUE_EZ_LOCK_TABLE, DEQUEUE_EZ_LOCK_TABLE.

Enqueue for Request lock for object.

Dequeue for Release lock for object.
