OverWrite Exits for Classes

Hi,
I am trying to create Overwrite exit for the class, while doing this SAP is creating local class in some include and giving me chance to put my code in the same method for which i am trying to create over write exit.
Problem is from this local class i am not able to access the global class methods in which i am doing all this stuff.
How can i use the methods of global class, though instation of this global class requires some mandatory parameters which i cannot provide...
is there any restrictions in using exits for class enhancements..
need your inputs....
Thanks..

Just wondering if anybody has answer for this??
when i create over-write exit for a method in class by using new enhancement framework, it creates local class i mentioned earlier in this thread.
using this local class i need to call private method of the global class is it possible or forbidden by SAP??
please let me know in general,
whether local classes in Global classes can access private methods of global classes??
whether global classes which itself has local classes def and implementations in it can access local classes methods????*
Please Suggest!!!!

Error message while creating Overwrite exit for a standard class method.

Hi,
I was trying to create an overwrite exit in class CL_HRTMC_AC_TA_DASHBOARD for method GET_DEVPLAN_ASSESSMENTS. I created an Enhancement Implementation first. But when I tried to insert Overwrite exit method, I got error message that "The class has not yet been converted to the new class-local types" . In the toolbar->Utilities, I saw an option "Convert Class-local types" and when I clicked that it asked for the Access key. Eventhough I cancelled the process, now I am seeing some inactive parts in from this class in my Inactive object list. When I try to activate, it's again asking for access key and not able to activate it. Not sure what has actually happened. Is it possible to revert it to old form? Please advice!
Thanks,

Inbound delivery is not part of Sales and Distribution. You might want to move your post to either the Logistics Materials Management (MM) forum or the Workflow forum.
Also sometimes search for OSS notes by the message class and number helps.

Pre,Post,OverWrite Exit for web dynpro ABAP methods of component,view

Hi,
my question is i have created overwrite exit for method of component controller in one enhancement implementaion say ENH1, and i also created overwrite exit for same method in another enhancement implemenation say ENH2, it means i have two different implemenations now,
My questions here is, will both Enhancement implemenations will "execute", if yes in what order..
Please clarify.
Thanks.

I'm afraid the information that Manas gave you is incorrect. In an overwrite method, the enhancement completely overrides and replaces the original method. Both versions are NOT executed. This is the risk you run with the Overwrite enhancement - you are choosing to completely replace the SAP delivered logic.
From the Online Help:
The overwrite exit method takes on the signature of the original method and overwrites it. This means that an overwrite exit is executed instead of the original method.
At runtime only one overwrite exit can be active. If several overwrite exits are active, a runtime error occurs.

Hi ALL,
Can anyone tell me the DB table where all the Classs and its methods are stored..?
Also if one could tell me that for any enhancement class implementation where are the OVERWRITE exit methods stored..

Hi Ill give u the complete steps for what im looking for...
Go to sfw1(switch transaction).
enter a switch like MILL_EHP_01A and execute.
A new transaction in which we get the package for the switch.
double click on the package name 'MILL_EHP_01A_SWITCH'.
traverse to Utilities->display_object list.
u will go to package builder.
click on dropdown 'enhancement' on the browser window,
click on 'Enhancement implementations' dropdown.U will get all the implementations name.
Double click on any one.
Now in the Right side u will see a class name on the button in the attributes tab.
click on the overwrite methods tab.
U will see the overwrite method dere( I want the tables where these methods are stored).
Click on the button with the class name.GO TO METHODS TAB.
u will reach the class builder.
There is a overwrite-EXIT column.
In that some methods will have a botton for overwrite exit , some will not.
Where this info is stored about Overwrite Exits./?

Overwrite Exit of method

Hi,
Can any one tell me how to enable the Overwrite exit of a method ? I want to enable the overwrite exit of a method CL_OPS_SWITCH_CHECK --> MM_SFWS_SERNO.
Regards,
Krishnam Raju

Hi Krishnam,
I have not idea so fas what an Overwrite exit may be. But you can do anything you want using implicit enhancements. Create a small enhancement project and apply it to method MM_SFWS_SERNO of class CL_OPS_SWITCH_CHECK.
I for one would not do it but look for a better solution. I do no
think that implicit enhancements are a good idea (of SAP) at all. Because you can apply just any change to any SAP code without having a modification.

Tolerance Limits for Class Character in Variant Configuration

HI all,
We are Using Variant Configuration, for this we have linked MIC's to Class character, When The Inspection Lot is created the Lower & Upper Limit in the specification comes as the character Value.it does not takes in to consedration the tolerance key assigned to it. For E.g. Charater Dia has value 20, & in the Tolerance key for 20 +/- 0.10 is maintained, when the Inspection lot is created the Upper & lower Limit comes as 20-20 instead 19.9 - 20.1
I have gone through SAP Note 210658, the sample code provided in note is for "Material Specification" I have tried the same with minor code correction the specifications in the lot comes as desired i.e. specifications in the lot consider the tolerance key.
Our Requirment is of task list, in the same not EXIT for task list is also mentioned but no souce code is provided, when we are using the above program (Used for Material Specification) after doing the desired changes, & when we run in de-bugging mode it shows all the calculations are being done, but finally in the lot specification appear as the charater value ( 20-20) & in the inspection lot One first MIC comes it delete's all other MIC's assigned in the Plan.
Has any body worked on this requirment, please let me know how to do the same, & if any body has used EXIT_SAPLQPAP_001 (Enhancement QPAP0001.)Plese provide me with the soution if any one has worked on it.

Urgent Help in User-Exit for MM!

Hi,
1. I am writing code in the Exit "EXIT_SAPLMGMU_001".
2. I have to pop-up error/warning messages for incorrect data entered in various fields/screens/views of MM01/MM02 transaction.
3. The Exit gets triggered when i press "SAVE" after modification.
4. When I create the Classification View, i enter the class type as "001" for material class.
5. Then i need to enter a value "Z_Product" in the class column(on the screen in classification view). This class is the "Product Class" (description).
 My problem is to find this value that i enter on screen before "Save" i.e. when i am creating material for the first time in MM01, i dont want the error message to pop-up if i am entering any value in the class column and also entering values in the internal characteristics for that class.
 Basically i want to read the values (before "SAVe") entered in the class column as well as want to know the values for the internal characteristics of the class.
 For Class, the std. field is "RMCLF-Class" , but i have no buffer field available in my exit that contains the value for the Class. I have also tried using "Get parameter ID", but it doesnt work.
 For Internal Characteristic values (of the class) that are entered in the tab(that appears on pressing "Enter" after filling the Class value) below the Class tab, i am fetching data from std. table AUSP to check for corresponding entries for that particular material number....but this table will get updated only after "SAVE" and so i would be able to read the values only in MM02.
Please help me in finding out a way for reading the class values & Characteristic values in my user-exit.
Thanks & Regards,
Tejas

Hi Ronak.
You can try with 'EXIT_SAPLCLFM_002' (CLFM0002). This is the exit for the classification view. You can get this for the transaction CL22N / CL24N.
This is also called in MM01 for classification values. This classification details are cross application components. So This is also called from other transaction.

But none of these seem to work.
Can anybody tell me which BADI or Exit that I can use?

To check for the suitable badi, Go to transaction SE24 and give the Object type as CL_EXITHANDLER and click on Display button.
Double click on method GET_INSTANCE, put a break point on case statement.
Execute your transaction and look for variable EXIT_NAME at your scenario then It will show the available badi's.
You can find the exits in many ways.
Get the developement class of the transaction code from SE93.
Then go to transaction SMOD and press F4 and give the Development class in Press ENTER, then it will show all the exits available for that transaction.
Or
Go to transaction SE80 and give the development class name and then expand the enhancements tree view then you will get the list of userexits for that corresponding dev class.
Reward if it is useful.

Screen exit for me32k for header and for items

hi experts,
i need a screen exit from me32k to add subscreen in :
1. items
2. header
thanks in advanced,
dana.

Hi,
Just some information on screen exits:
Screen Exit:
How to implement screen exit for a SAP standard transaction
Introduction
SAP provides standard transactions to enter data into database. But a client may want to maintain some additional information in SAP other than what is provided.
To make provisions for this, additional screens have to be provided and additional fields must be added into appropriate database table.
To pave way for this, SAP has provided the option for screen exits. Usually, SAP provides the following:
An append structure in the database table with the new fields.
A subscreen area into the standard screen where the programmer can attach his subscreen of his own program with the new fields.
A function group under which the new subscreen has to be created with the new fields.
Function exits to synchronize the PBO and PAI of the standard SAP program with the PBO and PAI of the subscreen so that data can flow back and forth between the standard SAP program and the program written by the developer for the subscreen. These function modules also exist in the same function group under which the subscreen will have to be developed.
Finally, a linkage has to be done between the subscreen area of standard SAP screen with the custom subscreen constructed by the developer.
Typically, SAP provides an enhancement in which the developer can create an append structure, use the function exits to synchronize the PBO and PAI of the standard SAP program and the custom subscreen program, and make the necessary linking( as mentioned above in step 4. But, again, this is not a hard and fast rule. Linking in some case, is also done by configurations.) SAP also usually provides the name of the function group under which the subscreen has to be developed.
Necessary guidance about implementing a screen exit development is usually available in the Documentation section of the enhancement ( can be availed by transaction SMOD).
Pre-Requisites
The developer to work on screen exit should have essential knowledge on the following:
DDIC concepts, including the knowledge of append structure.
Concept of SAP Enhancements and implementing them using Projects.
Concept of function exits.
Knowledge on Module Pool including subscreens, Tabstrip controls etc.
Steps
Guidelines
So, a developer can follow the guidelines mentioned below to implement a screen exit to a standard SAP transaction, as and when required:
Find out the Required Enhancements
Go to SMOD. Press F4 in the Enhancement field. In the next popup window, click pushbutton SAP Applications. A list will appear that contains information on all the enhancements, categorized under functional areas. Developer must search for the enhancements relevant to his functional area of interest for e.g., Purchasing, Asset Accounting, etc.
Note down the enhancements. Then, come to the initial screen of SMOD and view the documentation of each enhancement to find out which one is required for your development.
Utilize the Enhancement in a Project
After you have found one, do as directed in the documentation. Generally, the steps are as follows:
Create a project using CMOD including your enhancement.
Create the append structure with new fields.
Go to the desired function group and create a subscreen with the new fields. Write PBO and PAI for the subscreen, if required.
Use the function exits in the enhancement to link the PBO and PAI of the subscreen with that of the main SAP program supporting the SAP transaction.
Maintain necessary linkage between the subscreen area of standard SAP program with the custom subscreen developed along with the custom program name. This can be done in the project (developed by CMOD including the enhancement) or outside as a part of configuration.
Activate the project.
Test to ensure that required functionality are met.
Case Study 1
Add three new custom fields for Asset master and maintain information for them
Requirement
Three fields in the legacy system have to be maintained in Asset master. These fields are:
Original Asset number 20 characters
Location 2 15 Characters.
Model no 20 characters
Location 2 should start with L.
Pre-Analysis
Finding out the Enhancement
As described above, the enhancement is determined. It was found, that enhancement AIST0002 will serve the purpose. It contains the following components (can be viewed by transaction SMOD):
Exit Type Description EXIT_SAPL1022_001 Function Exit Check of User-Defined Fields when Using Create and Change BAPI EXIT_SAPLAIST_002 Function Exit Transfer Data for User Subscreens in PBO. EXIT_SAPLAIST_003 Function Exit Transfer of User-Defined Fields to SAP Master Data Transactions CI_ANLU Customizing Include Include structure to add new fields
Studying the Function Exits
The function module level documentation for the function exits are then viewed from transaction SE37. The documentation clearly laid out for the purpose for their use:
EXIT_SAPLAIST_002
Function module Level Documentation
This function module is called by asset master data maintenance at the start of the dialog. (When changing, it is called after reading of the data from the database; when creating it is called after the transfer of the default values from the asset class and reference asset.) The purpose of the function module is to enable this function group to recognize the master data. For interpreting or controlling master data fields that are important for user fields, it is possible to transfer to global variables at this point, so that they can be recognized when the user subscreens are processed.
Import Parameters
Understanding
This function module is called at the PBO to pass the information retrieved from the database to pass them to the custom subscreen and its underlying program. Import parameter : I_ANLU will be populated with the values for user-defined fields which will be passed to the subscreen program. So, there must be some sort of variable assignment from I_ANLU.
EXIT_SAPLAIST_003
Function module Documentation: This function module is called by SAP asset master data maintenance after the screens are processed, but before saving. The purpose of the function module is to transfer fields entered on user sub-screens of SAP asset data maintenance to the database for updating. The export parameter for this function module is:
Understanding
This function module will be used to transfer the user entered data in the subscreen fields to the main SAP program, which will then be saved into the database.
Studying the Documentation of the Enhancement
The enhancement documentation (as is viewed from the initial screen of SMOD] also supports the idea. Moreover, it informs that we need to develop a subscreen under function group XAIS. This is the function group under which the two function exit modules also exist. So, if the custom subscreen refers to the global data of the function group XAIS, then those values will also be available to these function exits as well.
Going to SE80 and viewing the function group XAIS helps us to inform that there are three DDIC tables declared for it:
Deciding the Final course of Action
After making all the investigations, the final course of action was determined.
SrlNo Step Justification
A project has to be created using transaction CMOD where the enhancement AIST0002 will be included.
Customizing include CI_ANLU has to be created with the custom fields demanded When CI_ANLU will be developed, the custom fields will get appended to the database table ANLU. Also, these fields will be used to create screen fields in the new subscreen.
A custom subscreen, say, 9000 will be developed under function group XAIS. The screen group for the screen will be CUST (or any name). The three custom fields added to table ANLU (by creating CI_ANLU) will be used to create new fields in the screen.
In the PAI of the subscreen, validation for Location to start with L will be added. The subscreen with three new fields has to be developed so that it can be attached to a subscreen area of the asset master screens.
In the custom include of the function exit module EXIT_SAPLAIST_002, the following code will be written:-
ANLU = I_ANLU. I_ANLU is the import parameter of this FM. The value is assigned to the global variable ANLU, referring which the three new subscreen fields are developed. So, data retrieved from database table ANLU will be passed to this FM as I_ANLU by the standard SAP main program. The value will be taken and passed to the global variable of the function group XAIS, so that the three custom fields (referring to ANLU of XAIS) get populated.
In the custom include of the function exit module EXIT_SAPLAIST_003, the following code will be written:-
E_ANLU = ANLU. The changed values in the subscreen fields exist in global variable ANLU for the function group XAIS. This function exit module will pass the data back to the SAP main program as E_ANLU.
Proper linkage/configuration has to be done so that the new subscreens get linked to the appropriate subscreen area of the Asset master screen. This has to be done otherwise, the new custom subscreen will not be displayed in the Asset master screens.
Development
Creating a Project to include the enhancement
Go to transaction CMOD and create a project.
Enter a description for the project. Then, click on the pushbutton Enhancement Assignments in the Application Toolbar.
Enter the name of the enhancement and Save.
Go to Components.
Creating Custom Include for ANLU
The screen shown below will appear, showing all the enhancement components under the assignment AIST0002. Double-click on the name of the Include Structure to create it.
Create the include structure with three new fields, as required. Then, save and activate it.
Develop the subscreen and the program
Go to transaction SE80. For the function group XAIS, create a new subscreen 9000.
Create it as subscreen.
Then, go to the Layout of the screen and create three new fields from Database table ANLU.
Drag the fields in the screen body and place them.
Then, save and activate the screen and come back to screen flow editor.
Create the PAI module to add validation for field Location 2, as required .
Activate the whole function group and come out.
Write code in the Function Exits to synchronize the programs
Now, code has to be written in the function modules EXIT_SAPLAIST_002 and EXIT_SAPLAIST_003 so that data flows to and fro between the main SAP program and custom subscreen program. For that, go back to transaction CMOD and change the function exits.
Write code in the function module EXIT_SAPLAIST_002 called once at the beginning of the transaction:
Write code in EXIT_SAPLAIST_003 to pass the data from the subscreen to SAP main program.
Then, activate everything the whole project and come out.
Complete the configuration to link the subscreen
The development portion is complete. Now, linking of the subscreen has to be done with the subscreen area of the main program. In most of the cases, this linking can be done in the enhancement itself. But, here, requirement is a bit different. It is done by configuration using SPRO.
Assets are created under Asset class. And for each asset class, there is a layout assigned to it. For a layout, there are multiple tab pages assigned to it. And, for each tab page, there are multiple screen groups/field groups assigned.
Here, the requirement is to create these three custom fields in the tab page General of asset master screen ( AS01/AS02/AS03/AS91).
Determine the Layout
To achieve this, first of all, we need to find out which layout is assigned to asset class 1000.For that, go to transaction AOLK( information has to be obtained from functional consultant).Select the Asset Class 1000 and click on folder General Assignment of Layout.
Here, for Asset class 1000, for all the user groups, tab layout SAP is assigned. Since layout SAP cannot be changed, it has to be copied and manipulated to include our screen group. Later, the new layout has to be assigned over here.
Create new tab layout
Go to transaction AOLA. Copy the tab layout SAP to create another layout, say, YSUB.
System will copy all the settings and will inform you about that.
Select your newly created layout and double-click on the folder Tab page titles.
You want to put your custom fields in the tab page General. So, select this tab page entry and double-click on the folder "Position of Groups".
Here, all the field groups currently residing in the tab-page General are shown. Add an entry for your newly created fields.
Select the group box from the list. An entry will come with U padded with the custom subscreen prepared by you.
Then, save and come out.
Assign the new Layout to Asset Class
Now, go to tcode AOLK and assign tab layout YSUB for asset class 1000.
Save and come out.
Test the Exit
Everything is over. Now, go to transaction code AS01/02/03 or AS91 to deal with an asset of asset class 1000. You will see your new fields added to the screen. Add values to themsave. Then, enter into the tcodes again to see whether the values entered by you are being displayed or not.

User Exits:
User exits (Function module exits) are exits developed by SAP. The exit is implementerd as a call to a function module. The code for the function module is written by the developer. You are not writing the code directly in the function module, but in the include that is implemented in the function module.
The naming standard of function modules for functionmodule exits is:
EXIT_<program name><3 digit suffix>
The call to a functionmodule exit is implemented as:
CALL CUSTOMER.-FUNCTION <3 digit suffix>
To find a Exit.
Goto Transaction -- Find The Package
SMOD >f4>Use the Package here to Find the Exits In the Package.
Else if you Want to search by Application Area wise ,
There is one more tab to find the Exits in the Respective Application Area.
Implementing the Exit-- CMOD Create ProjectsAssgn your Component .
Now Run ur Transaction to Check if it Triggers.
Thats it..
Suppose you need to find out all the user exits related to a tcode.
1. Execute the Tcode.
2. Open the SAP program.
3. Get the Development Class.
4. Execute Tcode SE84.
5. Open the Node 'Envir. -> Exit Techniques -> 'Customer Exits -> Enhancements'
6. Enter the Development class and execute.
Check out this thread..
