Need user exist?
Hello,
Need user exist in RFFOEDI1 to create custom segment to populate some fileds.
If any one done this type requirement please let me know the user exist.
Thanks,
chinna
Hi,
This way you can find any user exit:
1. Go to the program 'RFFOEDI1'. Get the package name from the program attributes.
2. Go to tcode 'SMOD'
3. Enter the package name of that program and execute.
You will get the list of exits available for that package. Based on its description and documentation of each exit you can identify which exit will be useful for you.

Saba

Hi all,
We are currently in the process of doing enhancement for Batch management.
SAP Version - 4.6C
For MIGO screen, requirement is that after posting details Batch is generated and GR is done. Followed by this expiry date of the batch is to be calculated.
My ABAP team has confirmed that no user exist is getting activated after posting of documents... Can anyone please suggest me what USER EXIT / BADI to be used??
regards,
Parshuramhi,
You want the calculate the expiry date? if it is so, then you can maintain it in shelf life field in MIGO. No need of any customisation.
This is how it works. SHelf life is the period of safe storage after production or date of manufacture. So if you mention, shelf life as 5 days and date of manufacture as todays date. date of expiry will be 5 days after. by maintaining this you can do the aging analysis.

How to check whether portal user exists or not using UM API.
Hi Experts,
Let us say i need to create an user account "PortalUser",i know how to create an user,setting first name,lastname,password for that.
but here before creating the portal user, i need to check whether that user exists or not.If user already exists ,then i need to skip the below for creating the user.
IUserFactory userFact = UMFactory.getUserFactory();
IGroupFactory groupFact = UMFactory.getGroupFactory();
IRoleFactory roleFact = UMFactory.getRoleFactory();
IUser tuser = userFact.getUserByLogonID("PortalUser");
IUserMaint newUser = userFact.newUser("PortalUser");
newUser.setFirstName("PortalUser");
newUser.setLastName("Test");
newUser.setEmail("PortalUser.Testatgmaildotcom");
//Locale PortalLanguage = new Locale(Lang.toLowerCase(), "");
Locale PortalLang=new Locale("en");
newUser.setLocale(PortalLang);
newUser.save();

userAcc.setPassword("test1test$");
userAcc.save();
userAcc.commit();
Thanks in advance.

SELECTs in user exists (P/S modules)
Hi,
I am implementing user exist triggered when an accounting document is posted ... P/S event no. 00001030. The problem is, that I need to read some records from BSID table ... this event is triggered right before a commit is executed, therefore I suppose that all database changes are already made, but not commited yet. Anyway, I've tried to read these database rows (in the same database transaction), but SELECT does not fetch any row! I know how database servers works, what are database sessions and database transactions ... I thought SAP system works in the same way ...
Can anybody explain me why ABAP does not see uncommited rows inserted by the same database session/transaction? Is there a way how to read these rows? I already tried to call my function by PERFORM ON COMMIT, ... same results ... also by CALL FUNCTION IN UPDATE TASK ... same results ...
Is there any sensible way how to read desired uncommited records?Hi,
Check while debugging where BSID table have those values or not.If yes then BSID table should declare in Table fields.If not then you need to dynamically assign the value of table to your workarea.
Below is the code which might help you:
Get the Name field enetered on Fb01 screen
ASSIGN ('(SAPMF05A)BSEC') TO <fs>.
wa_bsec = <fs>.
I hope it would help you.

User Exists In Sales Order Creation Program for adding "Reason For Reject"
Hi gurus
I have following requriement
As New Sales Order created (VA01) by default or at the time of saving the sale order, perticular "Reason for Rejection" should be set to each line item.
This is then can be removed in change (VA02) with Mass change.
We need this to review the sales order / block sales order from MRP run.
Please let me know how to manage this or is there any user exist for the same.
Thanks
Sunil KHi,
As per my knowledge the automatic creation of rejection order is not possible, still will check out and know.
but for urgent use you will have to follow the manual way of changing the line items from OK to blocked for apporoval so you can achieve their not passing on to MRP.
manual way is what is described below:
You can either reject the whole sales document or individual items.
Reject all items:
If you want to reject all the items, choose Reject document in the change modus for the sales document.
The system automatically selects all the items and you can enter a reason for rejection in the following dialog box.
Enter the appropriate reason for rejection and choose Copy.
The system assigns the same reason for rejection to all the selected items.
Reject individual items:
If you only want to reject some of the items, select those items in the item overview screen and choose Edit - Fast change of... - Reason for rejection.
A dialog box appears in which you can enter the appropriate reason for rejection.
Enter the appropriate reason for rejection and choose Copy.
The system assigns the same reason for rejection to all the selected items.
Reject individual items with different reasons of rejection:
If you want to enter different reasons for rejection for the items, choose the Reason for rejection tab page from the overview screen when changing the sales document.
You can enter a different reason for rejection for each item in the Reason for rejection field.
regards,
Siddharth.

Hi
USER EXIT
EXIT s are nothing but the R/3 Enhancements which allows you to add your own functionality to SAPs standard business applications without having to modify the original applications.
Purpose
To introduce the techniques of enhancement in standard SAP system. SAP creates customer exits for specific programs, screens, and menus within standard R/3 applications. These exits do not contain any functionality. Instead, the customer exits act as hooks. You can hang your own add-on functionality onto these hooks.
Use
They do not affect standard SAP source code.
When you add new functionality to your SAP System using SAPs exits, you do not alter the source code of standard SAP programs in any way. The code and screens you create are encapsulated as separate objects. These customer objects are linked to standard applications, but exist separately from SAPs standard software package.
They do not affect software updates.
When you add new functionality to your SAP System using SAPs exits, your objects (called customer objects) must adhere to strict naming conventions. When it comes time to upgrade a to a new software release, customer objects names ensure that they will not be affected by any changes or new additions to the standard software package.
Challenges
Customer exits are not available for all programs and screens found in the SAP System.
Modifications
Any change made to an SAP object in a customer system is called a modification. Customers usually modify their systems for one of two reasons. Either they make changes to the SAP standard in order to adjust the R/3 System to their specific business needs (actual modifications), or they alter individual SAP objects in order to correct an error (as recommended in an SAP error note).
You should only modify the SAP standard if the modifications you want to make are absolutely necessary for optimizing work flow in your company. Be aware that good background knowledge of application structure and flow are important prerequisites for deciding what kind of modifications to make and how these modifications should be designed.

ABAP DICTIONARY
Table Enhancements: There are two ways that you can add additional fields to tables without modifying your system.
Append Structures:
Append structures allow you to enhance tables by adding fields to them that are not part of the standard. With append structures, customers can add their own fields to any table or structure they want.
Append structures are created for use with a specific table. However, a table can have multiple append structures assigned to it.
Customizing Includes:
If customers know in advance that one of the tables or structures delivered to them by SAP needs to have customer-specific fields added to it, an SAP application developer can include these fields in the table using a Customizing include statement.
The same Customizing include can be used in multiple tables or structures. This provides for consistency in these tables and structures whenever the itself include is altered.
Append structures allow you to attach fields to a table without actually having to modify the table itself.
Append structures may only be assigned to a single table. A table may, however, have several append structures attached to it. Whenever a table is activated, the system searches for all active append structures for that table and attaches them to the table. If an append structure is created or changed and then activated, the table it is assigned to is also activated, and all of the changes made to the append structure take effect in the table as well.
You can use append structures in ABAP programs just as you would any other structure.
Note: When you copy tables that have append structures attached to them, the fields that were found in the append structure of the original table become part of the actual body of the target table.
Some of the tables and structures delivered with the R/3 standard contain special include statements calling Customizing includes. These are often inserted in those standard tables that need to have customer-specific fields added to them.
In contrast to append structures, Customizing includes can be inserted into more than one table. This provides for data consistency throughout the tables and structures affected whenever the include is altered.
Customizing include programs are part of the customer namespace: all of their names begin with 'CI_'. This naming convention guarantees that nonexistent Customizing includes do not lead to errors. No code for Customizing includes is delivered with the R/3 standard.
You create Customizing includes using special Customizing transactions. Some are already part of SAP enhancements and can be created by using project management (see the unit on 'Enhancements using Customer Exits').
The Customizing include field names must lie in the customer namespace just like field names in append structures. These names must all begin with either 'YY' or 'ZZ'.
When adding the fields of a Customizing include to your database, adhere to same rules you would with append structures.
ABAP DICTIONARY
Field Exits:
Field exits take you from a screen field with a data element reference to a function module. Field exits can be either global or local.
Field exit function modules adhere to the following naming convention:
prefix: FIELD_EXIT_
name: <data element name>_
suffix (optional): 0 to 9, A to Z
Text Enhancements:
Possible text enhancements include customer keywords and customer documentation of data elements.
Text enhancements differ from other application enhancements in that they take effect globally in all related SAP applications after activation (global enhancements).
Customer Exits
Function Module Exits
Menu Exits
Screen Exits
Function Module Exits
Function module exits add functions to R/3 applications. Function module exits play a role in both menu and screen exits. When you add a new menu item to a standard pull down menu, you use a function module exit to define the actions that should take place once your menu is activated. Function module exits also control the data flow between standard programs and screen exit fields.
Menu Exits
Menu exits add items to the pull down menus in standard SAP applications. You can use these menu items to call up your own screens or to trigger entire add-on applications.
SAP creates menu exits by defining special menu items in the Menu Painter. These special entries have function codes that begin with "+" (a plus sign). You specify the menu items text when activating the item in an add-on project.
Screen Exits
Screen exits add fields to screens in R/3 applications. SAP creates screen exits by placing special sub screen areas on a standard R/3 screen and calling a customer sub screen from the standard screens flow logic.
Exits are basically the hooks whcih SAP has provided to add your own code. There are two types of Exits:
1. Customer exits: Implemented as Function Modules within z includes. Anybody can change it and no access key is required.
2. User Exit: Implemented as subroutines within includes (any include except y or z includes). You need access for the specific include and then you can any subroutine (user exit) within that Include.
BADIs are the enhanced version of user exits where the same logic is implemented via classes and object (OOP)
Enchancement point is the latest once introduces with ECC6.0 . Not very sure about that but you can change it without any access key.
Please go through the following link which will help you understand the exits in a much better way:
