Use transaction SE11 to create a lock object for that table. When the lock object is created the ENQUEUE and DEQUEUE function modules will be created automatically.

Hi,

You can either use the standard way of locking by using :

data:lv_varkey TYPE rstable-varkey.

concatenate functional_location sy-mandt into lv_varkey .

*   Lock table
    CALL FUNCTION 'ENQUEUE_E_TABLEE'
      EXPORTING
        mode_rstable   = 'E'
        tabname        = 'IFLOS'
        varkey         = lv_varkey
      EXCEPTIONS
        foreign_lock   = 1
        system_failure = 2
        OTHERS         = 3.

*     Unlock table
      CALL FUNCTION 'DEQUEUE_E_TABLEE'
        EXPORTING
          mode_rstable = 'E'
          tabname      = 'IFLOS'
          varkey       = lv_varkey.

Or,

As mentioned above create a lock object via transaction SE11.

Go to transaction se11:

--> Enter lock object name e.g EZ_IFLOS

--> Click on create

--> Enter description

--> Click on tables tab

--> Enter 'IFLOS' as table name

--> select lock mode

--. click on save and activate.

2 function modules will be created as DEQUEUE_EZ_IFLOS and ENQUEUE_EZ_IFLOS .

Regards.
