FM to find user who locked the object using enqueue...

Hello,
How can I find name of user who enqueued the lock object in ABAP ?
Regards,
Jainam.

Hi Jainam,
See the SAP documentation, e.g. [FAQ - Lock concepts|http://help.sap.com/saphelp_NW04/helpdata/en/cb/168237d30d974be10000009b38f8cf/content.htm]:
How can I find out who is currently holding the ungranted lock? In other words, how can check the program after an ENQUEUE to determine which use is currently holding the lock so that I can let him or her know?
This graphic is explained in the accompanying text Answer
When the ENQUEUE_... function module is returned, the name of the lock owner is listed in SY-MSGV1.
If you don't want to attempt to lock an object and just check who might own a lock use function module ENQUEUE_READ. Lots of comments in the forum...
Cheers, harald

sometimes our user complain that, when he tyring to make a transaction to a specific customer's Account
its says 'Some other user access the same account, keep trying...' (like this).
and in this response I just kill that user's session. then he can make the transaction by reconnecting.
sometimes my solution(killing the session) can not slove this problem.it stayed even 5/6 hours long.
in this time,i cannot find any bloking session or such a long waiting session.
In this Scenario..
I need to find out who(SID,SERIAL#,USERNAME) locked the same ROW (not table).
There are many users who are locking different rows of the same table at the
same time. I need to find the one who locked my row.
is it possible to find out, who locked the specific customer's Account ?
I am trying to find out by the following query but failed.
SELECT s.SID, serial#, machine, osuser, terminal, b.object_name,

Just check with this query, find the lock and kill the session.
select b.session_id ,a.SERIAL#, a.username "Blocker Details"
from v$session a,dba_lock b
where b.session_id = a.sid
and b.blocking_others = 'Blocking';

How to find user who loaded the procs in DB

Hi guys how to find user who loaded procs in database ..and the date...
is there anyway..
i tried to look at all_objects..but it didnot workout..
thanks

That is correct. You will only have audit rows for item that you are auditing. I am suggesting you audit all DDL in a production database since production jobs should not perform DDL with the probable exception of truncate. This will provide this type of information going forward. It will not help you answer the question of who created the procedure last week?
Auditing is explained in the Security manual and the full comand syntax is available in the SQL manual.
You can easily write a purge the audit data to remove data once it is no longer of interest based on the date the audit row was created.

How to find users who are inactive.

Hi I want to find users who left the company. I ran program rsusr200 in se38 but not understanding which option will clearly give me the invalid users. Also i had a doubt. Does users with password deactivated that the user left the company.
Thanks in Advance for your help

The "password" field in this report will not necessarily show you users who have left the company. The password may be be "active" since this is a new user and they have not yet logged on. You would need to compare as well the field "Created On". I would use the last logon field as an indicator of who may have left - if someone has not logged on in 90 days, that could be an indicator.

How can I find out the list of users who has the access to IT 0008

All,
How can I find out the list of users who has the W R permission for IT 008
for others?
SUIM doe not look like giving me the correct results.
Please advise.
Thanks,
From
PT.

combine tables AGR_1251 and table AGR_Users on keyfield AGR_USERS
in tabel AGR_1251 select on Field LOW values IT0008.OR W OR R,
noiw you get also other values
So better solution run the query twice over AGR1251 first on IT0008 and secondly on values W OR R and then the result over table AGR_USERS
Youu also might put an additional selection on object P* (only selecting HR objects)
output wll be UID in table AGR_USERS

How to track the user who deleted the info object.

Dear Gurus,
In our BI system one info object has got deleted. If I need to track the user who has deleted that how can I track it(in which DBtable). And the complication is one user ID is being used by many people, in this case how can I track that from which machine the Info Object has been deleted(if there is any possibility to track the machines by IP address).
Kindly let me know if there is any procedure to find it out. Your help will be rewarded with a great honour.
Regards
Mohan Kumar

Hi dear,
you have to go in SLG1 transaction, and then select
Object: RSD
Subobject: IOBJ_DEL
External ID: (put here the name of your deleted IO)
Then choose a time range...and voilà, you can find the user who deleted the IO...
Hope it helps!
Bye,

How to find the user who approved the workitem.

Hi experts,
I have created a parking/posting workflow.
When the user Approves, parked document is posted and BKPF table is updated with WF-BATCH as user name.
Now I need to find the actual user who approved the workitem for posting.
My plan is:
1. Find the workitem id using the BOR, company code, document no, year, task no.
2. Find the user who processed the above obtained worktem id.
Please let me know the tables for the above points 1 and 2.
Or let me know if there is any other way to find the actual user.
Regards,
Karthik

Hi,
To get the workitem ID with respect to a specific business object instance make use of the FM SAP_WAPI_WORKITEMS_TO_OBJECT
To know who processed the determined workitem either you can make use of the FM SAP_WAPI_GET_WORKITEM_DETAIL or directly read the table SWWWIHEAD and you can find the actual agent WI_AAGENT this is the field which says who has executed the workitem.

ORA-00054 - Find user who have lock

Hi,
I'm using "select for update NOWAIT" in my application for editing records. It works but after I catch ORA-00054 I want to find username who have the lock.
The basic step is propably to query view v$lock and propably after then some else view.
Thanks for any idea/solution
SASA

You'll need to scroll down a while to get to your particular question in the thread I linked... I believe it's about a third of the way down.
It is not possible to know who is locking a particular row unless there are two sessions that are blocking each other. If session 1 has a lock on a particular row and session 2 requests a lock on that same row and session 2 is waiting for that lock to free up, session 3 can query the v$lock table to see which session holds the lock and which session is waiting for the lock. Assuming everyone is logging in with their own user name, you can join this information with v$session to find out the username of the person holding the lock. In your case, though, no session is ever blocked, so you cannot determine who owns the lock.

How to find out list user who did the printing

Any help will be much appreciated.

Text in VA02 - how to find the user who added the text

Hi
The user is adding text in the sales order through VA02, sometime after creating the order. This is not making any changes to the existing data, but adding the text in Header Text.
When trying to findout who made the addition of text (not changes) from VA03 - menu - environment - changes ---it is not showing any details regarding this. Please guide me how to find out the user who made the addition of text in sales order through VA02.
Thanks,
Ravi

Hi Ravi,
          I think there is no option available to find the name of the person who added text to the sales order.
         If the person who creates sales order, should also maintains the text we can find the name who created sales order. I am sure that u might be knowing the way.
       Still for the benefit of friends who r not aware, in the sales order> GOTO>Header data--> Sales tab.
