Reassigning the Locked object in ID

Hi Expert,
I amtrying to the edit the Communication channel object and it is throughing the error like " <object name> is already locked in another chnage list by user <user name> if necessary, you can reassign the other user's change list to yourself
can any body give me an idea how can we reassign the object?
THanks in Advance
Neeru

Hi Neeru,
you have 2 options.
1. Unlock the object
2. Re-assign the object to another user.
Unlock the object: in the XI home page click on Administration --> Lock over view then select the required locked object and click on unlock.
Re Assign the object: Go to ESR change list and select the required object then give the target user name and click on transfer then that object is transferred to the required target user.

What is the use for lock object and how to use the lock objects

Hi Guru's,
I am new to ABAP .Can you please clarify the that what is the use of lock object and how to use the loct object .what is use of the Deque & Enque function modules .

hi ,
below are some minfo about lock objects :
Lock Objects
These types of objects are used for locking the access to database records in table. This mechanism is used to enforce data integrity that is two users cannot update the same data at the same time. With lock objects you can lock table-field or whole table.
In a system where many users can access the same data, it becomes necessary to control the access to the data. In R/3 system this access control is built-in on database tables. Developers can also lock objects over table records.
To lock an object you need to call standard functions, which are automatically generated while defining the lock object in ABAP/4 dictionary. This locking system is independent of the locking mechanism used by the R/3 system. This mechanism also defines LUW i.e. Logical Unit of Work. Whenever an object is locked, either by in built locking mechanism or by function modules, it creates corresponding entry in global system table i.e. table is locked. The system automatically releases the lock at the end of transaction. The LUW starts when a lock entry is created in the system table and ends when the lock is released.
Creating Lock Objects
Lock object is an aggregated dictionary object and can be defined by using the following steps:
o From initial data dictionary screen, enter the name for the object, Click Lock object radiobutton and then click on Create. The system displays a dialog box for Maintain Lock Objects screen
o Enter short text as usual and the name for primary table.
-Save
-Select Tables option
From this screen you can:
Select secondary tables, if any, linked by foreign key relationship.
Fields for the lock objects. This option allows you to select fields for objects (R/3 system allows locking up to record level). Lock object argument are not selected by user but are imposed by the system and includes all the primary keys for the table.
1) Exclusive lock: The locked data can only be displayed or edited by a single user. A request for another exclusive lock or for a shared lock is rejected.
2) Shared lock: More than one user can access the locked data at the same time in display mode. A request for another shared lock is accepted, even if it comes from another user. An exclusive lock is rejected.
3) Exclusive but not cumulative: Exclusive locks can be requested several times from the same transaction and are processed successively. In contrast, exclusive but not cumulative locks can be called only once from the same transaction. All other lock requests are rejected.
Also, last but not the least, locking the object is logical (locking with any enqueue ) .so, you have to use the lock object while trying to access from second program .

How can we release the locked objects..

Hi,
I have created some objects such as pages and iviews in the portal. If i edited any of the object, then when next time when i access the object, I am hgetting a message as object is locked by admin, you canot edit it. Infact, I have logged in as admin.
How can we release the lock of objects?
Your help and suggestins solicited...
Best regards,
Sudhesh...

Login as the Portal Administrator.
Go to System Administration > Monitoring ->Detailed navigation -> Object Locking
Here you can find all the objects that are in locked state.
Now to unlock, tick mark the object that you want to work with & click on the "Unlock" Button.

The lock-object in synchronized clause.

If two threads are entering a synchronized statement, what condition on the lock-statement is then tested?
Say, we have:
Object lock1 = new Object() {
         public boolean equals(Object aObj) {
            return true;
Object lock2 = new Object() {
         public boolean equals(Object aObj) {
            return true;
      };Then the statements in the two following synchronized-clauses would be able to execute concurrently:
synchronized(lock1) {
    // Some statements
... in another thread
synchronized(lock2) {
    // Some statements
}The following statement (in my test) did not execute concurrently:
synchronized("test") {
// some statements
synchronized("test") {
   // Some statements
}...but the following did:
synchronized(new String("test")) {
// some statements
synchronized("test") {
   // Some statements
}This lead me to believe that a (object == object) condition was tested (not object.equals(object)). Is this correct?

This lead me to believe that a (object == object)
condition was tested (not object.equals(object)). Is
this correct?No. No test is performed on the references, and equals is not called.

How to verify the status of lock object???

Hello,
How to verify the status of lock object???
I need to know the status of the lock object and put the user in list.
Exists a FM for this?
Thanks!

You can check the list of lock objects for the ztable by this way....
Go to SE11, click the radibutton for lock object, then do F4 on the field. Click the "All Selections" icon, in the "Basis Table" field, put the table that you want the lock object for. click green check.

What are the lock modes in Lock object

What are the lock modes in Lock object ?
what are the divfferences between
Exclusive , cumulative
Shared
Exclusive , not cumulative
Could any body explain what happens in each table lock ?
How the lock consists ?

HI
Lock objects are used to synchronize access to the same data by more than one program.
The lock mode controls whether several users can access data records at the same time. The lock mode can be assigned separately for each table in the lock object. When the lock is set, the corresponding lock entry is stored in the lock table of the system for each table.
There are three types of lock modes
1.Exclusive
2.Shared
3.Exclusive not cummulative
Exclusive lock: The locked data can only be displayed or edited by a single user. A request for another exclusive lock or for a shared lock is rejected.
Shared lock: More than one user can access the locked data at the same time in display mode. A request for another shared lock is accepted, even if it comes from another user. An exclusive lock is rejected.
Exclusive but not cumulative: Exclusive locks can be requested several times from the same transaction and are processed successively. In contrast, exclusive but not cumulative locks can be called only once from the same transaction. All other lock requests are rejected.

Error while lock object creation

Hi
When I tried to create a lock object, I get the following error.
Error: "Total length of lock argument for table XXXXXXXXX longer than 150"
I have 3 tables in which Table1 is the check table for the value tables (Table2 & Table3). During the process of deletion of a record from Table1 (CT) I need the lock tobe established on value tables and then I delete all the corresponding entries in value tables are also deleted.
Would like to know If there is any other std ways of doing this ? and
Solution to overcome the error.
Regards
Karthick

Hi,
I think the error is becoz you have given too many LOCK parameters in the lock object. the total length of the PARAMTERS of lock object should not exceed 150.
By default all the KEY fields will be taken as Lock paramters, so your table key's length is more than 150.
Also why dont you create 3 lock objects for each table and then use only KEY's of each table as LOCK PARAMETERS.
Then Lock T1 record first then lock T2 and T3 records, then delete records from T2 and T3.
Then you delete T1 record.
The execute DEQUEUE_ALL.

Sesh

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.

About lock object

I have one TABLE with TABLE MAINTENANCE GENERATOR
and it has also LOCK OBJECT.
Now I have adjusted the table by making some normal fields as primary keys
and regenerated Table maintenance generator ,
It seems to me lock object also adjusted( I am able to see the newly converted primary key fields in lock object( in se11 ) ).
Does the lock object automatically adjusts ????
If lock object adjusts automatically --> what about the function modules ENQUEUE_ztable DEQUEUE_ztable ? these function modules also gets adjusted ?
do I need to check the associated lock object impact ?
How can I check ?

Hi,
No need to delete the Lock object. Just <b>remove</b> the Table which you modified from Lock object & <b>add again</b>. You can add the lock Parameters manually. It will be drived automatically from Table key fields.
You no need to delete the lock object.

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.
check this link for example.

Normally ABAPers will create the Lock objects, because we know when to lock and how to lock and where to lock the Object then after completing our updations we unlock the Objects in the Tables
http://help.sap.com/saphelp_nw04s/helpdata/en/cf/21eea5446011d189700000e8322d00/content.htm
purpose: If multiple user try to access a database object, inconsistency may occer. To avoid that inconsistency and to let multiple user give the accessibility of the database objects the locking mechanism is used.
Steps: first we create a loc object in se11 . Suppose for a table mara. It will create two functional module.:
1. enque_lockobject
1. deque_lockobject
before updating any table first we lock the table by calling enque_lockobject fm and then after updating we release the lock by deque_lockobject.
http://help.sap.com/saphelp_nw04/helpdata/en/cf/21eea5446011d189700000e8322d00/content.htm
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..

Differeence between Lock object and enqueue_e_table

Hi ,
what is diff between Lock object and enque_e_table. Where to use enqueue_e_table and where to use lock object.
I think with a lock object i can lock more than one table (passing tables in secondary table). Please correct me.

A lock object does not really "lock a table" though most of lock objects refer to a database table.
I explain:
The principle is that when 2 programs lock at the same time with the same lock object, only the first will succeed.
If you have a program which does not use the lock, it may update the database table without any problem.
All programs which update a table have to use the same lock object. Note that users are always able to update this table via SM30 as they don't know the lock object to be used.
enqueue_xxxx is the name of the generated function module used to lock the xxxx lock object. E_TABLE lock is ONLY used by SM30 if I remember well, so that to prevent one table from being updated via SM30 by 2 persons at the same time. But it is not related at all with programs which would also update this table.
