Auto Unlocking of locked objects in SM12

Hi All,
Is there a way that all the object locked in TCODE SM12 for over say 1 or 2 hours, gets unlocked automatically.
Any RZ10 parameter or via some other means.
I searched but couldn't get anything on the same.
Does anyone has some ideas on this. Please share, will be highly obliged.
Thanks & REgards,
Ashutosh

Hello Ashutosh
It would be a bad idea to auto cleanup locks in transaction SM12. Those locks have a purpose to keep your data consistent.
If you have issues that locks are set and cause issues for other users you should check where the locks come from and take action on it.
Setting different type of timeouts could help in some cases (as indicated above) to prevent users from leaving their screens in the middle of a transaction, possibly locking objects. User awareness can also help out (restricting reporting to the neccesary data and not requesting data from 10 years ago.
Do you currently have lock issues? If yes you can post on SDN to get some help on those.
Kind regards
Tom

Lock Object Creation

Hi,
Is it possible to create lock objects at runtime? if not, how do I lock tables at runtime when the table name is specified in the selection screen by the user?
Thanks.
Tyken

Hi tyken,
Try this.
Lock Objects are Created using Tcode SE11.
The Lock object name must be start with EZur name.
Mainly lock objects are used for locking the transactions, tables --etec.
Multiple users can not updated the same transaction at the same time.
Whenever u create a lock object using se11. SAP internally
creates a two function modules:
Enqueue_lockobjname ---For Locking purpose,
dequeue_lockobjname---For Unlocking purpose.
U make use of these fms to lock and unlock transctions, tables..etc.
Steps to create lock objects :
GO TO SE11
Select the radio button "Lock object"..
Give the name starts with EZ or EY..
Example: EYTEST
Press Create button..
Give the short description..
Example: Lock object for table ZTABLE..
In the tables tab..Give the table name..
Example: ZTABLE
Save and generate..
Your lock object is now created..You can see the LOCK MODULES..
In the menu ..GOTO -> LOCK MODULES..There you can see the ENQUEUE and DEQUEUE function
The example is as follws:
EPORT ZLOCK_UNLOCK
MESSAGE-ID ZBDC.
TABLES ZSTUD.
DATA text(8) TYPE c.
CALL SCREEN 100.
*& Module USER_COMMAND_0100 INPUT
text
MODULE USER_COMMAND_0100 INPUT.
CASE SY-UCOMM.
WHEN 'SELECT'.
SELECT SINGLE * FROM ZSTUD WHERE ROLLNO = ZSTUD-ROLLNO.
MESSAGE i004 WITH 'SY-SUBRC:' sy-subrc.
WHEN 'EXIT'.
LEAVE PROGRAM.
WHEN 'ENQUEUE'.
CALL FUNCTION 'ENQUEUE_EZLOCK1'
EXPORTING
MODE_ZSTUD = 'X'
ROLLNO = ZSTUD-ROLLNO
EXCEPTIONS
FOREIGN_LOCK = 1
SYSTEM_FAILURE = 2
OTHERS = 3.
CASE sy-subrc.
WHEN 0.
MESSAGE i004 WITH 'Enqueue successful'(001).
WHEN 1.
text = sy-msgv1.
MESSAGE e004 WITH 'Record already'(002) 'locked by'(003)
text.
CALL TRANSACTION 'SM12'.
WHEN 2 OR 3.
MESSAGE e004 WITH 'Error in enqueue!'(004)
'SY-SUBRC:' sy-subrc.
ENDCASE.
WHEN 'DEQUEUE'.
CALL FUNCTION 'DEQUEUE_EZLOCK1'
EXPORTING
MODE_ZSTUD = 'X'
ROLLNO = ZSTUD-ROLLNO
EXCEPTIONS
OTHERS = 1.
CASE sy-subrc.
WHEN 0.
MESSAGE i004 WITH 'Dequeue successful'(005).
WHEN 1.
MESSAGE e004 WITH 'Error in dequeue!'(006).
ENDCASE.
WHEN 'SM12'.
CALL TRANSACTION 'SM12'.
ENDCASE.
ENDMODULE. " USER_COMMAND_0100 INPUT

Lock object is not working automatically

Hi experts,
i have a problem , A table is updated by a program which is used by multiple user . I have used lock function module 'ENQUEUE_E_TABLE ' and 'DEQUEUE_E_TABLE' for that . when updation section occurs first user which come first go through it and for rest users amessage cones 'table is locked by XYZ user' . When first completes the updation resr users is not updating automatically they stand at that position where message comes. How to solve this issue?
Avadhesh Chandra

Hi,
We can lock the table before updating the entries. Two types of locks are there.
1. To lock the entire table. Here when the table is locked by one program, another program will not be able to modify it.
2. To lock the particular record only. Here when the record is locked by one program, the other program can modify records other than the one locked.
For option 1
Use the FM ENQUEUE_E_TABLEE to lock the table and FM DEQUEUE_E_TABLEE to unlock table.
For option 2
Go to SE11. There enter the name of your lock object and create it. Next screen you have to mention which field you want to lock.
For more info. on LOCK OBJECTS go to
http://help.sap.com/saphelp_nw2004s/helpdata/en/cf/21eea5446011d189700000e8322d00/content.htm
If you want to lock the entire table, then use the FM said in option 1 in DO-ENDDO loop.
Run the loop till it gets successful (sy-subrc = 0)
DO.
*Call the FM.
IF sy-subrc = 0.
EXIT.
ENDIF.
ENDDO.
If you want to just try some number of times rather than keep on looping then can use for eg: DO 100 TIMES.

Report to find Locked objects in sap system

Hi All,
does anyone know the report to find out the locked objects in an sap system?
or
name of the table that stores locked objects ?
or any other way through which we can find the number of locked objects ?
Thanks and regards
Abdul Hadi

Hi,
You can unlock locked objects in transaction SE03.
Click on Display Repaired objects.
You can see all the objects that are locked.
To unlock you can select the particular object and click on Unlock.
Do reward points if the answer to your question is met.

Create lock object with fun command

Hallo,
Is it possible to create a lock object with the fun command? I tried to use:
FUN ( ENQUEUE _<lockobject> , <interface> ).
When I fill the importing parameters, execute the script and afterwards refresh the interace than the import parameters are empty. Is there a way to create a lock object with the fun command or at least with inline abap?
regards,
Wolfgang

Hi Wolfgang,
in general your way of including the FUN command was correct.
The loss of import parameter values must have been caused by some other reason, not related to the invoke of enqueue. Maybe try it again.
If, for any reason, using FUN is not possible, it's always an alternative to use ABAP. .... ENDABAP. with correct ABAP coding inbetween (e.g. CALL FUNCTION ...).
Nevertheless regarding enqueue you need to consider, that the lock you set by running eCATT test scripts in this way, will last (only) as long as the session in which the function was called is active. Means, it lasts as long as you do not close the SECATT transaction (/n or similar) and not use commands like RESCON in your test script. Check your locks with transaction sm12.
Be aware, that interfering with an applications lock handling and strategy might also harm running transactions or the data processed by this transactions. Usually there is no need to call the enqueue modules from a test.
Best Regards
Jens

Where do I use These lock object FM's (Enqueue & D? and How do I use them?

I created lock object for user defined table (zconsist). The system automatically created 2 FM's (Enquiue & Dequeue).
I created a new TCode and accessing this with mulitple users to do some updates and inserts in that above table.
I used INSERT ZCONSIST statement in 5 places in my program (4 include programs).
Where do I use These FM's? and How do I use them?
I mean before inserting which FM I need to use? after immediately what fm used?.
every insert statemnt before i need to use the respective fm? so 5 places i need to call the respective FM is it right?
thank in advance.

Hi Sekhar,
Lock objects are use in SAP to avoid the inconsistancy at the time of data is being insert/change into database.
SAP Provide three type of Lock objects.
Read Lock(Shared Locked)
protects read access to an object. The read lock allows other transactions read access but not write access to
the locked area of the table
Write Lock(exclusive lock)
protects write access to an object. The write lock allows other transactions neither read nor write access to
the locked area of the table.
Enhanced write lock (exclusive lock without cumulating)
works like a write lock except that the enhanced write lock also protects from further accesses from the
same transaction.
You can create a lock on a object of SAP thorugh transaction SE11 and enter any meaningful name start with EZ Example EZTEST_LOCK.
Use: you can see in almost all transaction when you are open an object in Change mode SAP could not allow to any other user to open the same object in change mode.
Example: in HR when we are enter a personal number in master data maintainance screen SAP can't allow to any other user to use same personal number for changes.
Technicaly:
When you create a lock object System automatically creat two function module.
1. ENQUEUE_<Lockobject name>. to insert the object in a queue.
2. DEQUEUE_<Lockobject name>. To remove the object is being queued through above FM.
You have to use these function module in your program.

Lock object for Purchase Order

Dear Experts.
I am searching the function module "ENQUEUE_ " , which is for locking & Unlocking
the Purchase order(ekko-ebeln).
Please help me.
Thanks in advance,
Regards,
Rahul.

Hi,
Use the Lock object EMEKKOE to Lock and Unloack the Purchase orders
Use this FM to lock
MM_ENQUEUE_DOCUMENT
This is also used in the standard program. While enqueing,
if there is any error (sy-subrc 0), then it means,
that particular purchase order is already locked
Use Fm DEQUEUE_ALL to release all lock at the end of report execution.

Lock object funtion module for afpo table

Hii,
I have designed a screen and maintained batch field as mandatory field in that screen. and when i give batch number and hit enter the order number related to that batch number is automatcially picked. order and batch field's i am taking from AFPO table.now i want to lock this batch or order field so that no 2 user's can use same batch or order number while making entries.
can anyone let me know what is the function module i should use for enqueue and dequeue technics for these 2 fields.
Regards,
Venkat.
Edited by: venkat akella on Jun 29, 2010 1:40 PM

Hi Venkat,
For your requierment, you have to create a lock object for table AFPO using T code SE11.
The name of the Lock object should be start with EZ.
Then use the FM DEQUEUE_EZ**** & ENQUEUE_EZ**** For unlock and lock of the order.

Lock object for KONV table/Cluster table ??

Hi All,
Is it possible to set Lock/Enqueue cluster tables or in my case table:KONV (KNUMV field) ?.
OSS provided some programs without locks so was hoping if I could add before performing data manipulation.

Hi Nameeth,
you can use generic lock object E_TABLE with function modules ENQUEUE_E_TABLE, DEQUEUE_E_TABLE for locking and unlocking with parameters table name and key field.

Hi,
In a program to update the database table I need to lock the table Is this correct to use enqueue functional module before the modify & commit statement
and dequeue functional module after
modify & commit statement.

Hi,
We can use the function modules ENQUEUE_E_TABLE for locking tables and the function module DEQUEUE_E_TABLE for unlocking tables. With this method, we don't need to lock objects in order to lock the tables. In other words, any table can be locked/unlocked using these function modules.

Lock object issue

Dear Experts,
We are using the fn. Module "SD_SALES_DOCUMENT_ENQUEUE", to process a sales order with multi line item and to unlock the table, we are using "DEQUEUE_ALL", but for some reason, in the sales order processing when the system comes to next line item, the lock object is throwing an error, I'm not sure if this is due to the lock not being released on the order.
1st item success
2nd item failure
3rd item success
4th item failureu2026.not always the same pattern, but usually.

Lock Object: Enqueue and Dequeue

Hi
Im using VB.Net, SAP .Net to do data entry, updates to
SAP R/3.
Now, I need to lock the data during user changes on
particular documents.
What I done is I created a lock object in SE11. Then
it produce 2 functions which are the ENQUEUE and
DEQUEUE.
Since the data reading from Non-SAP, I check for Allow
RFC and my lock mode is Exclusive and Cumulative.
After that, I also created a remote-enabled RFCs to be
call from VB.Net. These RFCs is calling the ENQUEUE
and DEQUEUE.
When I tested in SAP itself, the locking data is
working perfectly. I checked in SM12, it does shows
the locking entry.
But when I try in VB.Net and call the function
modules, it does not shows any entry in SM12. It is
like nothing happen at all.
After that, I do little test. Firstly I lock the data
from SAP then I run VB.Net, and it does shows the
message who is currently locking the data.
Anybody could help me on this?
Thank you.
Regards.

See the following extract from documentation. Check if your lock object definition is satisfying all of them.
Reference Fields for RFC-Enabled Lock Objects
The type of an RFC-enabled function module must be completely defined. The parameters of the generated function module therefore have the following reference fields for RFC-enabled lock objects:
Parameters Reference fields
X_<field name> DDENQ_LIKE-XPARFLAG
_WAIT DDENQ_LIKE-WAITFLAG
_SCOPE DDENQ_LIKE-SCOPE
_SYNCHRON DDENQ_LIKE-SYNCHRON

Lock Object error during batch load

Batch load was delayed about an hour. First error message in the Server Log said "Object is already locked by user""Error 1053010 processing request [Lock Object]-Disconnecting"Then it went through a series of "Object locked by user admin" and "received client request: create Temporary Object(from user admin)"It did this several times until connection.Although from time to time we have had problems with Objects getting locked and preventing maintenance in the Application Manager. This is the first time that is has prevented a batch load. Does anyone know what could have triggered this during the load process?

This happened to us a lot, I think it's due to people opening objects, then letting their session time out, leaving a phantom lock.We solved the problem by calling the UNLOCKOBJECT function before any dimbuilds. 99.9% of the time this raises an error, "..object x is not locked..", but the rare time that the otl is inadvertently locked, it prevents the script from failing.

How to create a lock object in se11

hi all,
Can anyone tell me the step by step procedure to lock as well as unlock a particular object in se11 trns code. with an real time example.
thanxs in advance

You can create a lock on a object of SAP thorugh transaction SE11 and enter any meaningful name start with EZ Example EZTEST_LOCK.
Use: you can see in almost all transaction when you are open an object in Change mode SAP could not allow to any other user to open the same object in change mode.
Example: in HR when we are enter a personal number in master data maintainance screen SAP can't allow to any other user to use same personal number for changes.
Technicaly:
When you create a lock object System automatically creat two function module.
1. ENQUEUE_<Lockobject name>. to insert the object in a queue.
2. DEQUEUE_<Lockobject name>. To remove the object is being queued through above FM.
You have to use these function module in your program.
Creating Lock Objects
Procedure
1.Select object type Lock object in the initial screen of the ABAP Dictionary, enter an object name and choose Create. The name of a lock object should begin with an E (Enqueue).
The maintenance screen for lock objects is displayed.
2.Enter an explanatory short text in the field Short text.
You can then use the short text to find the lock object at a later time, for example with the R/3 Repository Information System.
3.Enter the name of the primary table of the lock object.
All other tables in the lock object must be linked with the primary table using foreign keys. There are also some restrictions on the valid foreign key relationships.
4.Select the lock mode of the primary table in the field below it.
The lock mode is used as the default value for the corresponding parameters of the function modules generated from the lock object.
5.Choose Add if you want to lock records in more than one table with the lock object.
A list of all the tables linked with the primary table using valid foreign keys is displayed. Select the appropriate table. The lock mode of the primary table is copied as lock mode. You can change this setting as required, for example you can assign the lock mode separately for each table.
6.Similarly, you can add a table linked with the secondary table just added with foreign keys. To do this, place the cursor on the name of the secondary table and choose Add.
7.If no lock mode is assigned to a table, no lock is set for the entries in this table when the generated function modules are called. You should not assign a lock mode if a secondary table was only used to define a path between the primary table and another secondary table with foreign keys.
8.Save your entries.
A dialog box appears in which you have to assign the lock object a development class.
9.You can (optionally) exclude lock parameters (see lock objects) from the function module generation on the Lock parameter tab page. This makes sense for example if you always want to lock a parameter generically.
To do this, simply deselect the Weight flag for the parameter. The parameter is not taken into consideration in the generated function modules. This parameter is then always locked generically.
9.The name of a lock parameter is usually the name of the corresponding table field. If two fields with the same name are used as lock parameters in the lock object from different tables, you must choose a new name for one of the fields in field Lock parameter.
10.You can define whether the function modules generated from the lock object should be RFC-enabled on the Attributes tab page.
If you set the Allow RFC flag, the generated function modules can be called from within another system with Remote Function Call.
11.If you permit Remote Function Calls for an existing lock object, you must ensure that the generated function modules are called from within an ABAP program with parameters appropriate for the type. You should therefore check all programs that use the associated function modules before activating the lock object with the new option.
12 .Choose Activate .
Result
When you activate the lock object, the two function modules ENQUEUE_<lockobjectname> and DEQUEUE_<lockobjectname> are generated from its definition to set and release locks.
You can find information about the activation flow in the activation log, which you can display with Utilities Activation log. If errors occurred during activation, the activation log is displayed immediately.
Pls reward points.

Ameet
