Creating logical locks generates two fm

Hi Expert!,
AS far I know, When we create logical locks in se11 transaction, two Function modules get generated by the the system.
My Question is , is there any other Function module which gets generated by system?
3rd FM?

Hii Mithilesh,
When u create a lock object In SE11 only 2 FMs are generated by the system that is "ENQUE" and "DEQUE" .as par i know no third FM is generated automatically.

Logical locking not working

Our system consists of ABAP and java stack. There are two server processes running on the system. We have a web application that is deployed. We want to lock an object in the init method of the servlet. We are using logicallocking to do that.
We want it so that when the application is deploying and running the init method on one server it obtains the lock. The other server process should wait till it obtains the lock.
This is the code I have
try {
                    lockOmscb();
                    _omscb.start();
                } catch (LockException e1) {
                    _logger.logInfoExt("Omscb instance already running, cannot access lock on object.");
                    // TODO Auto-generated catch block
                    e1.printStackTrace();
private void lockOmscb() throws NamingException, LockException, TechnicalLockException, IllegalArgumentException {
        Context initialContext = new InitialContext();
        LogicalLockingFactory factory = (LogicalLockingFactory) initialContext.lookup(LogicalLockingFactory.JNDI_NAME);
        _logger.logInfoExt("Got intial context lookup");
        _lock = factory.createLogicalLocking("NWCPM", "NWCPM workspace" );
        _logger.logInfoExt("created logical locking");
        lock.lock(LogicalLocking.LIFETIMEUSERSESSION, "NWCPM/OMSCB", cfg.toString(), LogicalLocking. MODEEXCLUSIVE_NONCUMULATIVE);
        _logger.logInfoExt("Got lock");
In the locking adapter I can see two locks being obtained at the same time. They are not getting it one after the other.
If I try to obtain the lock twice in the same method then it is throwing the lockException.
But this is not happening when the web application is being initialized in the two server processes.
Logicallocking is supposed to be access the lock between applications.
Is there a way I can acheive this ? If so how?
Can you please let me know.
thanks
Padmaja

Hi Padmaja,
the argument you are trying to lock is _cfg. As you do not deliver the code that defines this I cannot say what it contains, but it is easily predictable that this value is different in two different servers.
Make it a hard coded string with a value like "Humble" and then you are sure all instances will try to save exactly same value, which will make it work as expected.

Creating Source systems in two same logical BW systems from single R/3 sys

Hi All,
We are facing an issue while creating Source systems in two same logical BW systems, from single R/3 systems. Our Basis team is telling that if we want to connect the single R/3 system into 2 BW systems with same logical name, we will need to delete the source systems from one BW systems and create in another system. Also they told by doing so it will delete all the transfer rules and PSA table existing in the current BW system, which has the source system connectivity with the R3 system now.
Is this anyway to create the same source systems in two same logical BW systems, from single R/3 systems without deleting the transfer rules?. Also please help us to get anu OSS note or document explaining this in details.
Regards.
Muruganand.K

Hi Muruganand,
I dont think it is possible as connecting one R/3 Source System to two BW Systems.
If you could get the possible solution, please do reply to the post.

How to create logical directories with same name on two databases

Hi,
OS: Windows
Oracle Version : 10g
I have to databases in one oracle home. I have created some logical directories in one database. When I am trying to create logical directories with same name in another database, it is overwriting the first database directory paths with the second one
Can't we create directories with same name but different path in two databases on one machine?
Pls suggest me on this
Regards,
Vijay

I am trying to create logical directory using CREATE
DIRECTORY statement. I am very much aware that the
create directory statement doesn't create directory
on OS. But we can attach the physical directory on OS
to logical directory in oracle
My requirement is to create logical directories in
oracle mapping the OS directories. Both the
databases, wil have same logical directory names but
different OS directory mappingsIf I understand you correctly, you can do this:
On DB 1
CREATE OR REPLACE DIRECTORY same_dir_name as 'C:\myoracle\mydir1';
On DB 2
CREATE OR REPLACE DIRECTORY same_dir_name as 'D:\myoracle\mydir2';
What stops you from doing that ?
Note: If what you have is one database but different connections, then you are connecting to one database. The above second statement will drop and replace with the first one

Problem while creating table maintenance generator using two step

Hello All,
I have created a Z table in which I have 7 fields, out of which 6 are character fields and 7th field is of type INT4
Now when I create the maintenance generator using TWO STEP approach, the 7th field i.e., of type INT4 is not available in the first screen (the table control screen). This screen only has 6 fields for display.
But when I click NEW ENTRIES button, I get the next screen which has all the 7 fields.
But if I create the maintenance generator using SINGLE STEP, all 7 fields are displayed in the first screen.
Please suggest. Let me know if you require some more explaination.
Thanks & Regards,
Tarun

Hi Tarun,
Go to the layout and increase the size of the Screen. or at the screen attributes change the length and width values.
You know that initially the screen occupies default size only.
Hope this would serve your purpose.

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
hari

Hi,
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.
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

Lock(Enque/Deque) is a logical lock & database lock

Hi All,
I have gone through various portals and SDN too, and found that locks are the logical locks and sometimes database locks too but still have some confusion.
1) If these are the logical locks then why they are created by SE11 and once created then FM has been generated. All FM are stored somewhere right? So they would be in database.
2) If these are the database locks then why they are at the application server level and few more things.
Can anybody explain with the valid reasons? In which queue they fall and why?
Thanks.
An

Hi Anurag,
The SAP locks are created with naming standard EZ. They are not connected with the DB. It work like this
You create Lock -> FM is automaically generated as follow EXample: CALL FUNCTION 'DEQUEUE_EZARS_TRHDR_T'
EXPORTING
generated In your program you add CALL FUNCTION <name of your new lock enqueue FM>
3. if object is not locked you can modify it.
4. unlock it with second (dequeue) FM
Information about these locks are stored in queue on specific application server (usually central instance) - in SM51 you can see it with description "Enqueue".
So this is kind of mechanism that works if everybody goes according to rules. If someone will write it's own report were he access your objects, but he will ommitt this FM call (or ignore it's results), then he will be free to change it as he likes even if someone has already locked it.
To use DB lockes other technices are used like SELECT SINGLE * FOR UPDATE

How can I Generate two different reports from single execution of Test cases in NI teststand

Hi,
My requirement is to generate two different reports from NI teststand. One for the Logging of error descriptions and the other report is by default generated by the Teststand. How can i generate a txt file that contains error descriptions other than that mentioned in the default report?
Solved!
Go to Solution.

Do you need to do that just for these two sequences but not for other sequences? I don't see a problem to use SequenceFilePostStepRuntimeError. Create this callback in both sequence files and configure them to log into the same file. SequenceFilePostStepRuntimeError callback is called after each step of the sequence file if it has runtime error. You can access the calling step error information via RunState.Caller.Step.Result.Error property. Take a look to attached example.
The "other way" is useful if you need to log errors not for every step of the sequence file, but for some of them. This is more complex, because you need to create a custom step types for these steps. For the custom step you can create substeps (post-step in your case) which will be executed every time after step of this type executed. Then, this is you job to determine if error happened in the step, acces to step's error information is via Step.Result.Error property.
Also, be aware that step's post-expression is not executed in case of error in the step.

How to configure to generate two accounting documents for Mvt 645

Dear Experts,
I read all documents related to STO one-step procedure (mvt 645). They said that the system generate two accounting documents for 2 company codes (receing and issuing company codes) after goods issue reference to DO.
However, after configuration one step procedure and test my system, the system only generated one accounting document for receiving company code, not for issuing company code. In Material document, I saw 2 Mvt 645 and 101. In the lines having Mvt 645, I saw G/L account of cost-of-goods-sold.
Could you please to show me how to generate two accounting documnets automatically after goods issue referent to DO with Mvt 645?
Thank you so much,
Best regards,

My configuration steps are:
Step 1: preparation:
create customer and vendor master
extend sales & purchasing views for material master
Step 2: Assign customer number and the organizational units (sales organization, distribution channel, and division) to the Supplying plant and Receiving plant
IMG --> Materials Management --> Purchasing --> Purchase Order --> Set up Stock Transport Order --> Define Shipping Data for Plants
Step 3: tick on column "One step" for the line of supplying, receiving plant, and PO type cross transport order
IMG --> Materials Management --> Purchasing --> Purchase Order --> Set up Stock Transport Order --> Assign Document Type, One-Step Procudure, Underdelivery Tolerance
Step 4: assign delivery type NLCC for PO type cross transport order
IMG --> Materials Management --> Purchasing --> Purchase Order --> Set up Stock Transport Order --> Assign Delivery Type and Checking Rule
These above steps are in MM module.
Please help me,

I am using an NI PCI 6024 E board device for an analog output application. Can I generate two independent waveforms, one on each analog output channel?

I am using an NI PCI 6024 E board device for an analog output application. Can I generate two independent waveforms, one on each analog output channel? In attach I send a example of my vi to control one chanel, but i need to control both but with diferent waveforms.
Is the vi correctly programed to this propose?

Yes you should be able to do that. look at the signal generation examples shipped with LabView
You can create a 2 D array, with each row representing a wave form per channel. The number of points of the wave form (per row of the 2 D array) represent the number of points in the output buffer
The wave forms can have different amplitudes/shapes, and therefore they are independent in this sense.
However, you need to set the update rate,which is the same for both channels. The update rate together with number of points per buffer determines the frequency of the wave forms. This means the two wave forms will have the same frequency.
To have different frequencies, you need to have say, on wave form with one cycle per buffer, and the other waveform have 2 cycles
per buffer. in a case like that the frequency of the second channels is twice that of the first channel, and so on
The two wave forms are then not truly independent, they may have different amplitudtes/shapes, but related in frequency.

Thanks for the approach.
I have created a sequence which recursively looks through the Parameters.MainSequenceResults and if StepType is one of the Test Types then displays in summary report.
On the summary report I also wanted to get the name of the subsequcenCall if that subsequence call contained a valid TestType for summary report. For example if subsequenceCall step has a Action and String type. I wanted it to display as shown in Image1.jpg below. Currently it displays as shown in Image2.jpg.
Attached is the recursive sequence that I am using.

Generate two different pulses or more continuously with a PCI -6602

I have a PCI-6602 and Labview 8.0. I need to create a complex wavefrom output and I don't know how to create this waveform with the 6602, I know that I can create this pulse format by using the Agilent Pulse Generator but I would like to use the National Instruments. If somebody has an idea about how many counters and the physical connections that I need, also about how can I use labview to generate a complex waveform output.
I've attached the waveform that I need to generate continously and I hope that I can use the PCI-6602 for this purpose.
