Hi,

Use FM: ENQUEUE_ESORDER to lock your order number passed as parameter.

If sy-subrc eq 0, then your lock succeeds, else, it is locked by someone. The system will automatically display the message with the user name.

Hello.

In the begining of your tcode, try to enqueue same object that CO13 does. For that use statement like this one (CO03):

CALL FUNCTION 'ENQUEUE_ESORDER'
     EXPORTING
          AUFNR          =  AUFNR
          _SCOPE         =  P_SCOPE
     EXCEPTIONS
          FOREIGN_LOCK   = 1
          SYSTEM_FAILURE = 2
          OTHERS         = 3.
CASE sy-subrc.
   WHEN 1.
     WRITE aufnr TO l_aufnr NO-ZERO.
     WRITE sy-msgv1 TO l_user.
     MESSAGE e046(vl) WITH l_aufnr l_user.
   WHEN 2.
     MESSAGE e047(vl).
   WHEN OTHERS.
 ENDCASE.

hi can u tell me wat is that p_scope...plz

[valter_oliveira]

Hi again.

Scope is '2' by default. It's a control of blocking process. Controls how the lock or lock release is passed to the update program.

You have the following options:

_SCOPE = 1: Locks or lock releases are not passed to the update program. The lock is removed when the transaction is ended.

_SCOPE = 2: The lock or lock release is passed to the update program. The update program is responsible for removing the lock. The interactive program with which the lock was requested no longer has an influence on the lock behavior. This is the standard setting for the ENQUEUE function module.

_SCOPE = 3: The lock or lock release is also passed to the update program. The lock must be removed in both the interactive program and in the update program. This is the standard setting for the DEQUEUE function module.

DON'T FORGET TO DEQUEUE after program execution.
