Thanks

Hi Keshi,
Go to ABAPDOCU transaction.
Here u can find all the examples given by SAP and also u can find the documentation.
Hope this is helpful.

ABAP Tips and Tricks Section/Document

Howdy,
It'd be totally cool if we could share tips and tricks with each other!!!
I've had a llook at the new ABAP sections and I suppose its okay but it needs beefing up!
If someone'd be good enough to share their nuggets of knowledge eith us then I'D BE MOST GRATEFULL.
Also I'd like to see more ABAP tutorials!!!!
If no one else can be bothered to do this then i SUPPOSE I COULD RUSTLE UP SOMETHING. Just don't think I'll have it ready this side of Christams.
Again if anyone'd like to take this forward then great!
Take care y'all

Hi Steven,
Craig's links are goods and he made me laugh
Just to let you know - I've just submitted something to SDN that might be the kind of thing that you were looking for. I'll probably need to amend it so that it conforms to any SDN standards but then it'll be available for everyone to view/use.
So sit tight and I'll let you know how the work progresses.

Hafeez

Loop -- Select, for all entries, HOW TO ?

Hi,
I have followoing code.
LOOP AT table ASSIGNING TO lt_all_roles_all_objects.
ENDSELECT.
ENDLOOP.
How to tune this? I don´t understand how and where to use the for all entries command.
And what will happen with my append?
Can somebody explain me?
Thanks

Hi,
First you need to know some of tips in abap so that you can give good shape to ur program according to performance wise.
--Try to avoid the joins and use FOR ALL ENTRIES IN in place of joins.
--Try to avoid the MOVE CORRESPONDING
--Dont use the loop statements with in loop.
-- Dont write the select statement with in loop.
-- Better use the read statement in side loop intead of loop in side loop.
-- Use alway BINARY SEARCH in READ statement- in this mandatory thing is u need to sorty the internal table a/c to with key conditions.
etc................. like this u need take care some of abap tips so that u can achieve good coding standards..
coming to your coding.............
declare an internal table "itab_agr_1250" which contain fields mandt, agr_name, object, and deleted .
SELECT mandt agr_name object deleted
 from agr_1250
 into itab_agr_1250
 where agr_name = <cust_tab>-rolename
 and mandt in sp_mandt
 and deleted = ''.
IF sy-subrc = 0.
sort itab_agr_1250 by agr_name.
ENDIF.
loop at table assigning <cust_tab>.
read table itab_agr_1250 with key agr_name = <cust_tab>-rolename
 BINARY SEARCH.
final_Itab-field1 = itab_agr_1250-.....
final_Itab-field2 = itab_agr_1250-.....
final_Itab-field3 = itab_agr_1250-..... { USE single filed assign or move statement for each field instead of MOVE CORRESPONDING }
append final_Itab.
endloop.

How to delete buffer for HRP infotypes

Hi all,
I am using DFPS workbench and currently it stored buffer of hrp infotype when more than 1 record is being save . i am able to get the buffer using FM : RHOM_GET_BUFFER_FOR_INFTY. However when i try with 'RH_CLEAR_BUFFER' the buffer is still there when i try.
Any solution to this?
Thanks and Regards,
LH

Hi
Try using this FM:HR_PSBUFFER_INITIALIZE.

How to find screen exits?

Hello,
I want to know the procedure to find out the Screen exits available for a particular Txcode? Please to know this Concept.
Thks

Hi,
Finding Screen Exit:
1. in se11, goto table MODSAP
View table contents
2. in Type field, enter 'S' (for screen exit)
3. For that tcode, u should know the program name
or the CALLING SCREEN.
eg. SAPLLMOB
4. then type SAPLLMOB* and execute
For Further:
ERPGenie.COM -> SAP Technical -> ABAP -> Tips and Tricks -> SAP ABAP Field Exits
V4.6c onwards no longer supports field exits!!! In any case here's how to activate them:
Activation of the field exits and assignment of the dynpros is carried out using program RSMODPRF. For this purpose, the program must be started without parameters (input fields remain blank). If required, new field exits can be created using program RSMODPRF (see below for documentation).
Field Exits for Data Elements
Description
Maintenance transaction for creating and activating field exits
As part of the extension concept, SAP allows you to install a field exit for each screen field. Similar to the conversion exit, the system branches at the field exit at DCI (DATA COMMUNICATIONS INPUT) to a function module, if the field is an input field and a function code was triggered. The function module must adhere to the following naming convention:
Prefix: FIELD_EXIT_
Infix: <Data element name>
Suffix: _0 to _9 (optional), _A to _Z
The interface is automatically generated during the creation of the function module, and has 2 parameters:
Import parameter: INPUT
Export parameter: OUTPUT
After a function code has been triggered the contents of the field are made available to the FB via the "INPUT" import parameter. You can edit this and, when changed, make it available to the ABAP/4 processor in "OUTPUT". The input field contents are usually passed on: you can simply write OUTPUT = INPUT.
If, e.g., you have activated the field exit for the data element 'PROGRAM', then the fields of all the screens, which refer to the data element 'PROGRAM', branch to the function module FIELD_EXIT_PROGRAM. This includes the field 'Program' of the initial screen SAPMS38M0100 in transaction SE38, for example.
If you do not want the function module to be accessed from all screens, assign particular screens to the data element PROGRAM. By allocating an exit number, it is also possible to branch to other function modules with the corresponding suffix _0 ... _Z.
Example: You have assigned screen SAPMS38M0100 and exit number 5 to data element 'PROGRAM'. The corresponding field on SAPMS38M0100 branches to FIELD_EXIT_PROGRAMM_5.
As soon as you activate an exit, the corresponding screens are invalidated.
Note: Field exits are only taken into account during screen generation if the parameter abap/fieldexit = 'YES' is set in the system profile.
Requirement
Set the profile parameter abap/fieldexit = 'YES' before system start.
Limitations
The following ABAP statements are not allowed in the function modules of field exits:
BREAK-POINT,
CALL SCREEN, CALL DIALOG, CALL TRANSACTION, SUBMIT,
COMMIT WORK, ROLLBACK WORK,
COMMUNICATION RECEIVE,
EXIT FROM STEP-LOOP,
MESSAGE I, MESSAGE W.
Note:
Field exits cannot be edited with the debugger.
You should not use any external Performs in field exits. The ABAP processor shares the table work areas of externally called programs with those of the first caller. This could lead to errors at field exits that can hardly be analyzed, as field exits are sometimes slipped into the flow of the program at unforeseen events.
Questions and answers on field exits
1. A field exit was created with the CMOD and activated, but it does not get executed when the screen is called.
Since the field exit is not executed until DCI, some action must occur in the screen (e.g. press Return, saving....).
Set the abap/fieldexit profile parameter to YES and start the system again.
After the FIELD_EXIT... function module has been activated and the field exit has been activated, the transaction in whose screen the field exit is to be executed must be terminated. The screen is not generated until it is called.
Do not work on different application servers, otherwise there may be a delay before the field exit becomes active.
The profile parameter must be set either on all application servers or on none.
If the field exit is to be active in certain screens only, then you should check whether you have selected the correct program and the correct screen number (Careful with SUBSCREENS Do not rely on the F1 information for the field!
2. How does setting abap/fieldexit affect the performance?
If a screen is generated and the profile parameter is set, then the system checks in 2 tables (TDDIR, TDDIRS) to see whether a field exit has to be generated for the field. In practice the screen load after a Put is not generated until the screen is called. The user will not experience a noticeable delay, since screen generation is extremely fast.
3. Can the contents of other screen fields be read in a field exit?
In principle all fields can be copied to global variables in the TOP or the function group. However, since the order in which the field exits are called is not guaranteed, this possibility should not be used.
4. How does the field exit work in step-loop fields?
After data input to DCI the field exit will be called as many times as fields are visible on the step-loop. The SY-STEPL system variable is incremented each time. If a new value is assigned to be field, then it will be visible in the module between LOOP. ENDLOOP. This module will also be called as many times as there are visible step-loop lines.
5. Can field exits be debugged?
No. Field exits have to be tested in isolation in the development environment. To analyze problems that occur only in the screen environment, the relevant variables can be written to the file system using TRANSFER... and can be analyzed there.
6. What should one do if the field contents are not getting transported to ABAP/4?
Check whether you have assigned a value to the OUTPUT field.
7. When does the field exit get called in the case that there is a conversion exit attached to the data element?
The field exit will be called after the conversion exit. This means that the INPUT field contains the data in the same form as that in which the ABAP/4 program also gets them.
Regrdas,
Shiva Kumar

Regarding data transfers

hi,
can anybody tell me when we use SESSION METHOD,CALL TRANSACTION and LSMW.
urgent plz,
some say that for small amout of data we use CALL TRANSATION and for large volume of data we use SESSION METHOD .but i don't understand how many records is small and how many records is large. and for what type we use LSMW.
full points will be rewarded.
regards,
kiran

BDC
Session method.
1) synchronous processing.
2) can tranfer large amount of data.
3) processing is slower.
4) error log is created
5) data is not updated until session is processed.
Call transaction.
1) asynchronous processing
2) can transfer small amount of data
3) processing is faster.
4) errors need to be handled explicitly
5) data is updated automatically
ABAP Tips by : Nagaraj Muniyappa
Batch Data Communication (BDC) is the oldest batch interfacing technique that SAP provided since the early versions of R/3. BDC is not a typical integration tool, in the sense that, it can be only be used for uploading data into R/3 and so it is
not bi-directional.
BDC works on the principle of simulating user input for transactional screen, via an ABAP program.
Typically the input comes in the form of a flat file. The ABAP program reads this file and formats the input data screen by screen into an internal table (BDCDATA). The transaction is then started using this internal table as the input and executed in the background.
In Call Transaction, the transactions are triggered at the time of processing itself and so the ABAP program must do the error handling. It can also be used for real-time interfaces and custom error handling & logging features. Whereas in
Batch Input Sessions, the ABAP program creates a session with all the transactional data, and this session can be viewed, scheduled and processed (using Transaction SM35) at a later time. The latter technique has a built-in error processing mechanism too.
Batch Input (BI) programs still use the classical BDC approach but doesnt require an ABAP program to be written to format the BDCDATA. The user has to format the data using predefined structures and store it in a flat file. The BI program then reads this and invokes the transaction mentioned in the header record of the file.
Direct Input (DI) programs work exactly similar to BI programs. But the only difference is, instead of processing screens they validate fields and directly load the data into tables using standard function modules. For this reason, DI programs are much faster (RMDATIND - Material Master DI program works at least 5 times faster) than the BDC counterpart and so ideally suited for loading large volume data. DI programs are not available for all application areas.
Differences between bdc session method and call transaction method.
The most important aspects of the batch session interface are: - Asynchronous processing - Transfers data for multiple transactions - Synchronous database update During processing, no transaction is started until the previous transaction has been written to the database. - A batch input processing log is generated for each session - Sessions cannot be generated in parallel
The most important aspects of the CALL TRANSACTION USING interface are: - Synchronous processing - Transfers data for a single transaction - Synchronous and asynchronous database updating both possible The program specifies which kind of updating is desired. - Separate LUW for the transaction The system performs a database commit immediately before and after the CALL TRANSACTION USING statement. - No batch input processing log is generated.
Explain in detail with example what is batch input session?
Batch Input Session:
- It is a sequence of transactions, which is generated when user run a particular program.
- It contains the accounting documents that are to be created. The SAP system stores these transactions until you decide to process them online.
- It does not update transaction figures until the session has been processed. Using this technique, you can transfer large amounts of data to the SAP system in a short time.
Three processing modes of executing Batch Input Session :-
(1) Run Visibly : You can correct faulty transactions online & work step-by-step through the transactions not yet executed.
(2) Display Errors only : You can correct faulty transactions online. Transactions not yet executed, but without error, run in the background.
(3) Run in Background : Recommended by SAP.

LSMW
SAP Data Migration with LSMW
No ABAP effort are required for the SAP data migration. However, effort are required to map the data into the structure according to the pre-determined format as specified by the pre-written ABAP upload program of the LSMW.
The Legacy System Migration Workbench (LSMW) is a tool recommended by SAP that you can use to transfer data once only or periodically from legacy systems into an R/3 System.
More and more medium-sized firms are implementing SAP solutions, and many of them have their legacy data in desktop programs. In this case, the data is exported in a format that can be read by PC spreadsheet systems. As a result, the data transfer is mere child's play: Simply enter the field names in the first line of the table, and the LSM Workbench's import routine automatically generates the input file for your conversion program.
The LSM Workbench lets you check the data for migration against the current settings of your customizing. The check is performed after the data migration, but before the update in your database.
So although it was designed for uploading of legacy data it is not restricted to this use.
We use it for mass changes, i.e. uploading new/replacement data and it is great, but there are limits on its functionality, depending on the complexity of the transaction you are trying to replicate.
The SAP transaction code is 'LSMW' for SAP version 4.6x.
For those with the older SAP version (4.7 and below), the data migration programs might not have been pre-loaded.
You can download the LSMW at no cost from SAPNet under Services, SAP Methodology and Tools, category Tools.
If you are an existing SAP customer with an OSS ID, you can access the SAP Service Marketplace to download the LSWM for your Basis teams to install to your SAP system: http://service.sap.com/lsmw
The LSM Workbench carries out the following tasks:
Reads the transfer data from one or more files (for example, spreadsheets, sequential files etc.)
Converts the data from the source format into the target format
Note that with background processing, the input file must not be located in the presentation server. Access to presentation server files is only possible when you are working online.

hi

Hi,
some of FAQs
Field exits (SMOD/CMOD) Questions and Answers
1. Field exit was created with CMOD, but is not processed when calling the screen.
- Since the field exit is not processed until PAI, an action must be triggered on the screen (Return, Save, ...).
- Set profile parameter abap/fieldexit to YES and restart the system.
- After activating the function module FIELD_EXIT... and the field exit, leave the transaction on whose screen the field exit is to be executed. The screen is not generated until the transaction is started.
- Do not work on different application servers since there may be some delay before the field exit is activated.
- The profile parameter must be set on all or none of the application servers.
- If the field exit is to only be active on specific screens, check whether you chose the correct program and the correct screen
 number (take care with subscreens).
- Using SE51 -> Field list, check that the screen field does have a reference to a data element. In the name of the field exit use the name of the data element and not the field name.
- After transport, field exits are marked as active but will not be processed.
 Tip: First try deactivating the field exit once more and then afterwards, activate it again.
2. How is performance affected by setting abap/fieldexit?
- If a screen is generated and the profile parameter is set, a check is run on 2 tables (TDDIR, TDDIRS) to see whether a field exit must be generated for the respective field. In practice, the screen load is not generated until the screen is selected after an
update. The user should not notice any difference because screen generation is very fast.
3. Can you read the contents of other screen fields in the field exit?
- In principle, every field exit can store its value in the global variables of the function group (TOP) and hence make them
available to other field exits. Note here that field exits are always called and not only if an entry is made in the field or if the field is empty. In addition, it is not possible to make any assumptions about the order in which the field exits will be called in the future.
4. How does the field exit behave on step loop fields ?
- After the user has entered data, the field exit is called in PAI as often as there are visible fields in the step loop. The system
variable SY-STEPL is incremented each time. If a new value is assigned to the field, it is displayed in the module between LOOP and ENDLOOP. This module is also called once for each visible step loop line.
5. Can field exits be debugged ?
- No. Field exits must be tested separately in the ABAP/4 Development Workbench. For errors which only occur in the screen environment, it is helpful to write interesting variable to the file system using TRANSFER... . These can then be analysed there.
6. What can you do if the field contents are no longer transported to to ABAP/4.
- Check whether a value is assigned to the field OUTPUT.
7. When is the field exit called if a conversion exit is attached to the
 data element ?
- The field exit is called after the conversion exit. This means that the INPUT field receives the data in the same format as the
ABAP/4 program also receives it.
8. Although a global field exit is inactive, a function module is called which does not exist (for example FIELD_EXIT_PROGRAMM_@)
- This is an error in the kernel which no longer occurs as of 3.0C. As a temporary measure, it is useful to assign a program and a screen which do not exist to the field exit and then activate the field exit.
9. Field exit is not visible in CMOD, although created.
- If you want to create a field exit for a data element, a function module is proposed with the name FIELD_EXIT_. This
function module must exist for the field exit to work. If you do not create this function module, but do create one with a suffix,
the data element is not displayed in CMOD.
10. Field exit is not executed although it is active.
- Fields which do not have the 'Input field' attribute usually do not trigger a field exit. The field exit is designed to allow an
extended input check. It is therefore only called for input fields - even if they are not ready for input at runtime of the application by LOOP AT SCREEN.
This rule does not apply, however, if the field is located within a steploop. Here the field will be always activated, even if it is
invisible.
- Field exits can only be executed for fields that are directly related tothe dictionary. If the relation is indirect, i.e. via an ABAP declaration ( LIKE ), no field exit can be executed.
11. Field exits on check buttons do not work
- Field exits are only intended for input fields. As check buttons count as graphical elements, you cannot install field exits on
them.
12. Field exits do not work on selection screens

WD ABAP performance tips and tricks

Hi all,
I was wondering if there is any good approach to build WD applications so performance does not have to suffer. Do you know of any good documentation on this topic?
Thank you,
Georgy

Hello, Georgy,
From my experience, I follow some guidelines. These can be correct or not, but from my researches across SDN and other sources (help.sap.com and Ulli's book), it's proven to be good guidelines. Of course, I'll be presenting here only those tips related to WDA, not ABAP. Here they are:
1. Design your Context nodes carefully:
- Avoid non-Singleton nodes;
- Make your supply functions as simple as possible;
2. Controllers:
- If you use a component (such as ALV or MESSAGE_MANAGER) frequently, instantiate it at WDDOINIT and save it as a public attribute of the COMPONENTCONTROLLER. This way, whenever you need to call a method of the component, you can refer to wd_comp_controller->attribute->method.
3. Views:
- Instead of using dynamic programming to control properties of view elements (visibility, read-only, text, etc), use context attributes. This way, you can control, for instance, the visibility of an element in any method, not only inside WDDOMODIFYVIEW;
4. Methods:
- Use the WDA framework correctly: if you need to consist user entered data, use WDDOBEFOREACTION; if you need to control aspects of the view, use WDDOMODIFYVIEW;
- Learn the Phase Model better than the back of your hands
Well, that's some guidelines I use, and I'd like you to comment it also, or further expand this list.
Regards,
Andre

Tips for a new ABAP programmer...

Hello experts,
I am a fairly new ABAP programmer that usually modifies existing reports. I am really having a hard time on understanding all those synatx. Can you guys give me tips on how to better understand reports/programs?how do you analyze reports? any tips and suggestions would really helpful to me.Thanks a lot guys!

Hi,
No Problem dont worry SDN will help you a lot.
Actually every one is new for the new technologies.
Actually here as an ABAPer 1st try to learn DE-BUGGING as much as you can.
Try to do it from START-OF-SELECTION event 1st line on wards.
Put a break point on start of selection line event and execute it.
Here in debugging you need to carefully observe the behaviour of the program, logic etc etc.
Next understand the FORMS when they are triging and their reusability.
Under stand the Events sequence.
Later try to obsorbe the Syntax of the commands as much as you can.
Thanks.
If this helps you reward with points.

ABAP OO - Any tips on where to start?

Hi all,
we are in 6.40 and I have read Jovelyn's blogs on ABAP OO.
We are now ready to start developing the workflow and I am a bit unsure about how to get started...
The workflows are for HR business processes. A few questions:
1 - If anyone told me they were about to start developing workflows for HR, I would immediatley suggest that BUS1065 and EMPLOYEET would be used. If we are going to used ABAP OO, can anyone give me a hint about which classes are normally required? e.g. you will need one to represent the employee, another one to represent position, etc
2- I would rather not have to replicate BUS1065 / EMPLOYEET in a new class; I am aware that we can reference BOR objects in ABAP OO classes but I don't know how to do it or how to use it.
3 - I noticed several classes CL_HRPA_INFOTYPE_*. I am assuming they represent the several Infotypes delivered in HR. Any hints about how to 'test' these classes - I didn't quite grasped yet how to 'test' these classes - I am trying!
4 - If I want to use CL_HRPA_INFOTYPE_* in my workflows, I need to add IF_WORKFLOW interface. How to do that? Do I say that CL_HRPA_INFOTYPE_* is a Superclass and add the interface IF_WORKFLOW in my ZCL_HRPA_INFOTYPE_*?
Thanks in advance for any help you can provide.
I really want to start using ABAP OO in my workflows, but feeling really unsure about how to do it!
Cristiana

Thanks Mike, I am still septical about going for ABAP Classes - I know it is the direction that SAP wants to go, but with so little information about how to do it properly, I am afraid of doing more harm than good.
You suggested that I should use a BO as an attribute of a class. So, are you suggesting that a should create a class called ZCL_EMPLOYEET, assign the BO EMPLOYEET as an attribute type SIBFLPORB and add any extra bits and pieces that I need in class ZCL_EMPLOYEET?
Have you worked with classes CL_HRPA_INFOTYPE_*. I am assuming they represent the several Infotypes delivered in HR. Any hints about how to 'test' these classes - I didn't quite grasped yet how to 'test' these classes - I would like to see what they do, but I am not getting it.
Thanks for any help you can provide,
Regards,
Cristiana
