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.

How to create a Java Object dynamically

I want to convert a "DataObject (SDO) " into "Pure java object".
For this i want to create a java object with the fields in Dataobject, and this should be in generic way.

I want to convert a "DataObject (SDO) "What is a "DataObject (SDO)"?
into "Pure
java object".What is a "Pure java object"?
For this i want to create a java object with the
fields in Dataobject, What is stopping you? Do you not know how do define a class? Do you think you can add fields to the Object class? If that's what you mean, you're out of luck.
and this should be in generic
way.What do you mean "in generic way"? "Generic" is a very generic term. There are lots of contexts in which it could apply and lots of different possible meanings for "generic way."
You'll have to explain your queston more clearly.

How to create a xml object dynamically

Hi all,
In my current project the database is returning the query result in xml string format(using oracle's DBMS-XML package).
Now I need to use this xml string and build a xml object and transform it into XSLT and then in a servlet and then pass it to the browser and display it using xsl stylesheets.
Can some one help me in building an xml object using a string( the xml string is in the xml format i.e in <..> format) and then transform it into xslt in the servlet and send across to the browser.
Any hands on code or references to the code will be most favourable.
any help regarding this issue will be most appreciated. Pls do reply as early as possible as I do not have much time to implement this.
Thanking in advance for your kind help.
Srinivas.

What's an "xml object"?
If you want to transform it using XSLT (transforming it "into" XSLT doesn't make much sense), you can transform direct from the string. Like this:try {
TransformerFactory xformFactory = TransformerFactory.newInstance();
Source xsl = new StreamSource("your.xsl");
Transformer stylesheet = xformFactory.newTransformer(xsl);
Source request = new StreamSource(new StringReader(yourXMLString));
Result response = new StreamResult(out);
stylesheet.transform(request, response);
catch (TransformerException e) {
System.err.println(e);
}By the way, if you haven't seen this code before then I suggest you go and read ERH's book about XML with Java:
http://www.cafeconleche.org/books/xmljava/chapters/index.html

How to create a view object and attach with extended AM

Hi,
I tried to create new vo and attach this vo with the extended AM. But it is throwing error like 'PC.NAME : invalid identifier' (Actually this PC.NAME is exiting one).
Now i want to know how to create a view object similar like seeded one but with one additional condition in the where clause.
It is possible though extension, but i want to create two view object similar like seeded one, one with some other condition in the where clause
and another one with some other condition.
So for my requirement, i'll extend one VO and i'll add my condition but how to do it for second condition.
But i want same seeded VO with two different condition.
Any suggestions please,
SAN

SAN,
There is no need to attach the newly created VO with extended AM. You need to attach the same with the standard AM.

How to create an UI element dynamically on action in drop down?

Hi,
How to create an UI element dynamically on action of selecting a value from the drop down?
help out with the steps i need to follow..

Hi,
Dynamic UI Element creation
We can create it only in the WD Modify View.
Get the instance for the Root UI Element Container.
Create the UI element Ex: Input Field, Text View etc.
Bind the UI Element to the Attribute Value.
Now bind the UI Element to the Root UI Element Container.
 IWDTransparentContainer root =(IWDTransparentContainer)view.getRootElement();
 IWDDropdownByIndex DdbName = (IWDDropdownByIndex)view.createElement(IWDDropdownByIndex.class,"DdbName");
 IWDDropdownByIndex DdbAge = (IWDDropdownByIndex)view.createElement(IWDDropdownByIndex.class,"DdbAge");
 IWDDropdownByIndex DdbGender = (IWDDropdownByIndex)view.createElement(IWDDropdownByIndex.class,"DdbGender");
 IWDNode Mad =wdContext.getChildNode("Person",0);
 IWDAttributeInfo NameAtt = Mad.getNodeInfo().getAttribute("Name");
 IWDAttributeInfo AgeAtt = Mad.getNodeInfo().getAttribute("Age");
 IWDAttributeInfo GenderAtt = Mad.getNodeInfo().getAttribute("Gender");
 DdbName.bindValue(NameAtt);
 DdbAge.bindValue(AgeAtt);
 DdbGender.bindValue(GenderAtt);
 root.addChild(DdbName);
 root.addChild(DdbAge);
 root.addChild(DdbGender);
Dynamic Action Creation
Create the Action in the Action tab.
Create a Button.
Get the reference for the created action (Through the Event Handler).
Bind the Action to the Button.
Bind the Button to the Root UI element Container.
IWDButton ButGo = (IWDButton)view.createElement(IWDButton.class,"ButGo");
IWDAction ActGo = wdThis.wdCreateAction(IPrivateStartView.WDActionEventHandler.GO,"Click");
ButGo.setOnAction(ActGo);
root.addChild(ButGo);
Now write the required code for the Event Handler that is associated with the Action.
//@@begin onActionGo(ServerEvent)
 IWDNode Mad = wdContext.getChildNode("Person",0);
 wdComponentAPI.getMessageManager().reportSuccess(Mad.getCurrentElement().getAttributeAsText("Name"));
 wdComponentAPI.getMessageManager().reportSuccess(Mad.getCurrentElement().getAttributeAsText("Age"));
 wdComponentAPI.getMessageManager().reportSuccess(Mad.getCurrentElement().getAttributeAsText("Gender"));
//@@end

How to create new authorisation object for Transactions?

Hi,
How to create new authorisaton object and how to assign that object on a transaction code?
Case ->
The transaction code VL01N have the object called V_LIKP_VST under Class "LE_V" that have two auth. fields. one is 'Activity' and other one is "Shipping Point/Receiving Point".
Here I want to add "Storage location" also. I have created one object called "Z_LIKP_VST" under same calass "LE_V". and added "Activity", "Shipping Poing/Receiving Poing" and "Storage Location". After that I added that object ("Z_LIKP_VST") for particular transaction through "SU24". I maintained the "Display check indicator" for VL01N.
I created one new role and assigend the particular transacation for a user. but still SAP taking V_LIKP_VST insted of Z_LIKP_VST.
How can I change my Z_LIKP_VST on profile.
Please help
Thanks in Advance
Lal

Hi Kariyath,
I suppose its not about interest but a MUST.. sorry but.. unless u include the Logic in the program how can SAP pick these custom Z objects ?
after u create them and assign to a Tcode in SU24 there is no logic to check these objects. Frankly i see no other chance.... unless SAP comes to us with a great easy way to input these Custom objects
Keep looking and please Update me if u have any Inputs....on this front..
All the Best

Create custom authorization Customer specific object
If you have requirements that cannot be met using the P_ORGIN and P_ORGXX authorization objects (for example, because you want to build your authorization checks on additional fields of the Organizational Assignment infotype (0001) that are customer-specific), you can include an authorization object in the authorization checks yourself.
Create the authorization object using transaction SU21. Make sure you keep to the customer name range (Z/Y). To be able to use the new authorization object you have created in the master data authorization check, the object must contain the INFTY, SUBTY, and AUTHC fields. You can use any of the fields of the Organizational Assignment infotype (0001) for the other fields. You can also use customer-specific additional fields provided they are CHAR or NUMC type fields.
After you have created the object, you must start the RPUACG00 report. This report overwrites the MPPAUTZZ standard include with the code that is needed to evaluate the authorization object you created. Note: Technically speaking, this involves a modification. However, SAP fully supports this procedure. And you should not have more maintenance work as a result of this modification.
          Note: that if you use customer-specific authorization objects, you must maintain these objects in transaction SU24 (Maintain Assignment of Authorization Objects to Transactions) in the same way as you maintain the authorization objects P_ORGIN, P_ORGXX, and P_PERNR
AUTHORITY CHECK OBJECT Object_name
            ID fieldname1 FIELD fieldvalue1
            ID fieldname2 FIELD fieldvalue2
            ID fieldname3 FIELD fieldvalue3.
             If sy-subrc eq 0.   "Authorization exists

How to create Authority check object

Hello Gurus,
How to create Authority-check object 'ZABC'
                                                         ID 'TABLE' FIELD 'ZTABLE'.
Please tell me detailed procedure.
Thanks in advance.

Dear Zubera,
Creating Authorization Fields
In authorization objects, authorization fields represent the values to be tested during authorization checks.
To create authorization fields, choose Tools --> ABAP Workbench --> Development --> Other tools --> Authorization objects ® Fields.
To create a authorization field:
1. Choose Create authorization field.
2. On the next screen, enter the name of the field. Field names    must be unique and must begin with the letter Y or Z.
3. Assign a data element from the ABAP Dictionary to the field.
4. If desired, enter a check table for the possible entries. For    more information about check tables.
For more information about AUTHORITY-CHECK, see the keyword documentation of the ABAP Editor.
You can often use the fields defined by SAP in your own authorization objects. If you create a new authorization object, you do not need to define your own fields. For example, you can use the SAP field ACTVT in your own authorization objects to represent a wide variety of actions in the system.
Assigning an Authorization Object to an Object Class
Each authorization object must be assigned to an object class when it is created.
Choose Tools --> ABAP Workbench --> Development --> Other tools --> Authorization objects --> Objects.
You can also create authorization objects in the Object Navigator (SE80).
Creating / Choosing Object Classes
The system displays a list of existing object classes.
Object classes are organized according to the components of the system.
Before you can create a new object, you must define the object class for the component in which you are working. The objects are not overwritten when you install new releases.
You can also define your own object classes. If you do so, select class names that begin with Y or Z to avoid conflicts with SAP names.
Creating an Object
Enter a unique object name and the fields that belong to the object. Object names must begin with the letter Y or Z in accordance with the naming convention for customer-specific objects.
You can enter up to ten authorization fields in an object definition. You must also enter a description of the object and create documentation for it.
Ensure that the object definition matches the AUTHORITY-CHECK calls that refer to the object.
Do not change or delete authorization objects defined by SAP. This disables SAP programs that use the objects.
You can regenerate the profile SAP_ALL after creating an authorization object.
Best Regards,
Rajesh
