Here some code that works for me.

* Make sure that no one else is running this program
* This is the locking mechanism for this program.
  PROGRAM = SY-REPID.
  CALL FUNCTION 'ENQUEUE_ESINDX'
       EXPORTING
            SRTFD          = PROGRAM_NAME
            SRTF2          = 0
            _WAIT          = 2
       EXCEPTIONS
            FOREIGN_LOCK   = 1
            SYSTEM_FAILURE = 2.
  IF SY-SUBRC <> 0.
* Give message that someone is running the program
  ENDIF.

Hi abhishek,

import-parameter SRTFD of fm is defined

as INDX-SRTFD (= char 22)

i don't know if it's useful to copy and modify fm (?)

can't you rename your program ?

Hi

Don't copy the function module! It's a generated lock object one.

The technique being used here is to re-use a lock object that relates to a generic system table.

As SAP locking is logical, not physical, it doesn't really matter that a generic system table is used here,

as there is very low likelihood of people conflicting with the lock argument.

However, the INDX table has only a 22 character key.

Why don't you create your own 'Z' lock object. Do a where-used list on view TRDIR for other

lock objects using it. Use one of them as a template.

It'll take you 15 minutes and you'll learn all about locking.

Then just call your new generated lock function module as above.

Cheers

Dom

Hi,

Just use the standard Lock object : http://help.sap.com/saphelp_nw04/helpdata/en/cf/21eea5446011d189700000e8322d00/frameset.htm

(see also The SAP Lock Concept (BC-CST-EQ) )

Hello Judith,

Please do spend some time reading and understanding the question. Editor Lock has got a different functionality. It allows only the creator of the program to modify it. Which is certainly not what is being asked.

And further it is not a good idea to mainuplate the TADIR/TRDIR and other such tables directly.

Once again, I must tell you to make sure that your response is relevant. Irrelevant and misleading answers may be subject to censoring. And I don't generally want to do that.
