Advantages/difference of HR ABAP than ABAP

Hello Abapers,
Good day..I would like to know the advantages of HR ABAP compared to ABAP only.actually i was thinking what are the benefits of an Abaper where he knows how to program in HR Abap than an ABAPer who knows FI module ,MM or just a simple ABAper...is there any difference?
Kindly help

Hi Anji,
hello world..
Kindly help me about my problem in using alv grid set parameter id.actually i need to call the tcode FB01...but the available parameter id are only belnr and BLART
but i need to pass a value for BLDAT,XBLNR and NEWKO.unfortunately they dont have parameter id ...so i can i pass a value for fb01 without parameter id..
another is although belnr and BLART have parameter value in fb01..they cant pass the value even i set the parameter for them...the system always prompt "make an entry in all required fields" and cursor is in document date(bldat)
kindly see my code below.

Advantages of 'HR_INFOTYPE_OPERATION' Function Module In ABAP-HR

HI Experts,
What are the Advantages of 'HR_INFOTYPE_OPERATION' Function Module In ABAP-HR rather than BDC Both methods?
Thanks in Advance.
Naveen

Hi
The function module 'HR_INFOTYPE_OPERATION' can be used to update,insert,modify,delete and change in the same function module.
Codings are also very simple there by calling this FM in case of conversion program.
Performance is also good when compared to session method.
Speedy performance in conversion programming.
The sample codings is given.
CALL FUNCTION 'HR_INFOTYPE_OPERATION'
     EXPORTING
          INFTY          = '0009'
          NUMBER         = EMPLOYEENUMBER
          SUBTYPE        = SUBTYPE
          OBJECTID       = OBJECTID
          LOCKINDICATOR = LOCKINDICATOR
          VALIDITYEND    = VALIDITYEND
          VALIDITYBEGIN = VALIDITYBEGIN
          RECORDNUMBER   = RECORDNUMBER
          RECORD         = P0009
          <b>OPERATION      = CHANGE </b>
          NOCOMMIT       = NOCOMMIT
There by changing the operation field into "INSS","MOD","DEL" alone we can do conversion program easily.
Then if no commit ='X' then it does't get updated in database so that it will be easy for us to check whther the fields get updated properly in database.
If no commit = ' ' then the possible fields get updated in database.
Thanks,
Sakthi.

Whats the difference between ABAP stack, ABAP+Java stack and Java stack

Hello,
I have a nagging doubt about the difference between the ABAP stack, ABAP+Java stack & the Java only stack. I believe that the method of applying the kernel for all the 3 types is different.
Also can we apply the ABAP support packs through JSPM.
Please put some light on this.
Thank you

Hi Zaheer
ABAP Stack
AS ABAP is used to provide the ABAP foundation of SAP NetWeaver.
Part of AS ABAP is the Search Engine Service (SES), which enables users to search for
business objects using Search and Classification (TREX). SES accesses Search and
Classification (TREX) functions through the Search and Classification (TREX) ABAP
client. SES replicates the business objects from the ABAP application to Search and
Classification (TREX), so that it can apply Search and Classification (TREX) search
functions to them. When a user enters a search query, the Search and Classification
(TREX) system responds to it, not the database for the ABAP application. For more
information, see the document Installation Guide SAP NetWeaver TREX Single Hosts /
Multiple Host.
Java stack
AS Java is used to provide the Java foundation of SAP NetWeaver. Among the key
capabilities of AS Java are:
J2EE Engine a J2EE 1.3-compliant application server for running enterprise
applications. In addition to the pure J2EE standard technologies, the J2EE
Engine implements complementary technologies, such as Web Dynpro or Web
Services, that are targeted at supporting large-scale, real-business application
development projects.
SAP Composite Application Framework Core (CAF Core) is a service-oriented
architecture for building and deploying composite applications. It enables
modeling of different service types entity services that represent a domain
model, application services that implement business logic, and external
services that offer connectivity to back-end services by means of remote
function calls (RFCs) or Web services. Usage type AS Java comprises the CAF
Core runtime environment, while design time tools are part of the SAP
NetWeaver Developer Studio.
Web Dynpro is the user interface technology for developing professional
business applications for mobile as well as for desktop clients. Web Dynpro
applications can easily be integrated into SAP NetWeaver Enterprise Portal,
providing a unified layout for the end user as well as enhanced navigation
support. Web Dynpro also allows, for example, the development of interactive
forms using the Adobe document services.
Adobe document services is a set of runtime services that provide a range of
form and document creation and manipulation functions such as:
Converting XML form templates (created using Adobe LiveCycle Designer)
to PDF and various print formats
Setting Adobe Reader rights to enable users to fill in and annotate forms,
save and print them locally, and include digital signatures for authentication
using the free Adobe Reader software
Extracting data from SAP applications into Interactive Forms and transferring form data
back into SAP applications using XML
ABAP + Java Stack
Contains both functionalities.
I hope this helps

Difference between Reports in normal ABAP and Reports in CRM

Hi Experts,
I am new to CRM. Can someone tell me the Difference between Reports in normal ABAP and Reports in CRM.
It will be very useful if someone explains with example.
Some where in SDN i read in CRM we should not select statment. Then how to fetch data?
Please give me more basic concepts about CRM programming.
Thanks,
RAGU

Hi Ragu,
You can find much information at http://service.sap.com/crm-inst.
Go to Installation & Upgrade Guides -> SAP Business Suite Applications -> SAP CRM
Check the CRM version in which you are working and get the documents.
FMs are specific to the requirement. Like all Business Partner related FMs generally start with BUPA* or BAPI_BUPA*.
For CRM transaction data you can get info using FM CRM_ORDER_READ. To create a new transaction use CRM_ORDER_MAINTAIN and CRM_ORDER_SAVE.
More information can be fetched by surfing through the SDN threads and checking in SE37 t-code.
Hope this helps!

Hi Friends ....Difference between SAP memory and ABAP memory

Hi Friends,
I faced a interview and they ask this question
What is the difference between SAP Memory and ABAP memory..

conti
SAP Memory
SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement.
Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens.
ABAP Memory
ABAP memory is a memory area that all ABAP programs within the same internal session can access using the EXPORT and IMPORT statements. Data within this area remains intact during a whole sequence of program calls. To pass data to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse.
A simple example of ABAP memory is using the EXPORT/IMPORT statements.
Here in this program, I get the data, export it to memory,
clear out the internal table in my progam, then reimport the data into it and write out the data.
You probably wounldn't do this in a normal program,
but this is how you can pass data from program a to program b when A Submits program B.
report zxy_0002 .
data: it001 type table of t001 with header line.
select * into table it001 from t001.
export it001 = it001 to memory id 'ZXY_TEST'.
clear it001. refresh it001.
import it001 = it001 from memory id 'ZXY_TEST'.
loop at it001.
write:/ it001-bukrs, it001-butxt.
endloop.
SAP Memory
SAP memory is a memory area to which all main sessions within a SAPgui have access.
You can use SAP memory either to pass data from one program to another within a session,
or to pass data from one session to another.
Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters).
These parameters can be set either for a particular user
or for a particular program using the SET PARAMETER statement.
Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement.
The most frequent use of SPA/GPA parameters is to fill input fields on screens
ABAP/4 Memory
ABAP memory is a memory area that all ABAP programs within the same internal session can access
using the EXPORT and IMPORT statements.
Data within this area remains intact during a whole sequence of program calls. To pass data
to a program which you are calling,
the data needs to be placed in ABAP memory before the call is made.
The internal session of the called program then replaces that of the calling program.
The program called can then read from the ABAP memory.
If control is then returned to the program which made the initial call, the same process operates in reverse.
SAP memory
The SAP memory, otherwise known as the global memory,
is available to a user during the entire duration of a terminal session.
Its contents are retained across transaction boundaries as well as external and internal sessions.
The SET PARAMETER and GET PARAMETER statements allow you to write to, or read from, the SAP memory.
ABAP/4 memory
The contents of the ABAP/4 memory are retained only during the lifetime of an external session
(see also Organization of Modularization Units).
You can retain or pass data across internal sessions.
The EXPORT TO MEMORY and IMPORT FROM MEMORY statements allow you to write data to, or read data from, the ABAP memory.

Difference between Report painter and abap query .

can anyone please tell me the difference between the report painter and the ordinary alv,clasical reporting and also the difference between Report painter and abap query. How the output format will be in Report painter. If anyone has any documents please send it to
[email protected]
Thanks,
Joseph.

hi,
ABAP Query is an ABAP Workbench tool that enables users without knowledge of the ABAP programming language to define and execute their own reports.
In ABAP Query, you enter texts and select fields and options to determine the structure of the reports. Fields are selected from functional areas and can be assigned a sequence by numbering.
link for abap query --
https://forums.sdn.sap.com/click.jspa?searchID=221911&messageID=2790992
whereas the Report Painter enables you to report on data from various applications. It uses a graphical report structure that forms the basis for the report definition. When defining the report, you work with a structure that corresponds to the final structure of the report when the report data is output.

Advantages in Webdynpro Java Over WD ABAP

Hi All
Can you please let me know what are the advantages in webdynpro java over WD ABAP??
if anybody helps quickly then it would be great help to me
Thanks
Trisha Rani

Hi,
Both WDA and WDJ are almost same in designing and programming.
In relation to the business packages SAP already provided allmost all of them in java and in the future all the Business packages also available in ABAP. It's all how you want to develop the application. In sap portal world some applciation which we can develop with ABAP Web Dynpro and some applications with JAVA Web Webdynpro as SAP Web AS available as dual stack.
If someone already has a strong ABAP background and has WD for ABAP available they should probably use that. If they are a J2EE developer they should probably use WD for Java but it is likely they will also then need some ABAP support for the backend systems.
I think more customers may be asking for WD for Java projects simply because it has been around longer and is more widely available to customers where as some cutomers prefer to develop their application using ABAP Web Dynpro because of SAP propritary. But ultimately it's again all our interest and customer.

What are the differences between inactive and active ABAP objects?

Can anybody tell me what are the differences between inactive and active ABAP objects?
In my opinion, an active object is compiled and system wide available, that means the system do not have to compile the program again before run or use the object. While An inactive object is not system wide available and every time you run an inactive object, firstly the abap runtime will have to generate a tempory runtime object and this inactive object can not seen by others.
Am I right? Can anybody kindly tell me other differences?

Hi,
"When it is inactive, it is like it would not exist at all:" no - it's like it only exists to you
"If we just saved that one means it is stored in application server not in database": no - the inactive version is also stored in the database. You can log off and log on and it will still be there, in its inactive status.
"Only active objects can be executed.": no - inactive objects can be executed by you
When you create or modify a program, it is inactive until you activate it.
With a change, there are two versions of the program stored in the database - the active version (as it was before you made your change), and the inactive version. If you attempt to run the program, you'll run the inactive version - the one with your changes. Everyone else on the system will run the active version.
In this way, you can make changes without affecting anyone else.
Once you activate your program, then the inactive version becomes the active version.
With a create, there is no active version, until you hit the activate button. This means ONLY you can run the program.
An additional benefit of this model, is that if you make a change, save it, and then change your mind without activating, you can recover the active version into the editor, using version management.
A downside is that sometimes you have to activate your change before you can test it, if it interacts with other, active, programs.

Kumar

hi
Object Oriented prg
A programming technique in which solutions reflect real world objects
What are objects ?
An object is an instantiation of a class. E.g. If Animal is a class, A cat
can be an object of that class .
With respect to code, Object refers to a set of services ( methods /
attributes ) and can contain data
What are classes ?
A class defines the properties of an object. A class can be instantiated
as many number of times
Advantages of Object Orientated approach
Easier to understand when the system is complex
Easy to make changes
Encapsulation - Can restrict the visibility of the data ( Restrict the access to the data )
Polymorphism - Identically named methods behave differently in different classes
Inheritance - You can use an existing class to define a new class
Polymorphism and inheritance lead to code reuse

Replication issue in ABAP to ABAP scenario

Hello,
I have a ABAP to ABAP replication scenario where I am replicating custom and standard tables like MDMA but found below issue.
The replication current action is struck in "Replication (Initial Load)" with Initial load is getting done but not replicating data afterwards.
Also, the tables is keep on switching between "Failed" and "In process" status. I checked the system is sufficient number of jobs.
I found below error message after checking the show error log.
I restarted the replication many times and even created the configuration but no luck.
Please enlighten me to fix this issue...

I really appreciate if some one provide the more details(Pros & Cons ) regarding cosuming web services and I also want to know is there any other way to consume web services in ABAP.
Thanks.

<i> is there any other way to consume web services in ABAP</i>
you can use cl_http_client class to make your program to act as http client and post the soap message too webservice. This way you dont need to generate proxy, but you should know the soap message format.

ABAP or ABAP+JAVA in Solman Installation?

Hi,
We are going to implement Solution Manager 7 (SR3).
1. I would like to ask whats the best installation variant in installing solution manager? (ABAP or ABAP+ JAVA)
2. What are the additional capabilities of SolMan if we install ABAP+JAVA and not ABAP only?
We are planning on using solution manager for:
- Central Administration
- Change request management
- Root Cause Analysis
- Delivery of SAP support service
Thanks,
Roel

Dear
Solution Manager has to have ABAP+JAVA stack so your choice is easy.
Solution Manager Java Stack offers additional functionality as well as tools.
For example Solution Manager Diagnostics.
Kind regards

Differences between Procedural ABAP & OOPs ABAP

Thanks and Regards

Let me add some comments about the difference in design between Procedural Programming and OOP. If you are used to writing procedural/imperative code, then it will take a while to adjust to object oriented code, because the design is quite different. These are a few points that may take some time to get used to.
I. In procedural code, you normally think about functionality first and pass the data around to several procedures to be manipulated until eventually you get our result, whatever that may be. In OOP, you think about data first, and attach functionality to the data to which it applies. In this way, you create a virtual object with its own properties and actions that can be performed on it or by it.
II. Objects should always have a consistent and valid interface. What I mean by this is that public attributes and methods should accurately reflect the state of the data at all times. It should not be possible for code that uses an object to call the methods in the wrong order and get invalid results. Each method call should update all data necessary to keep the data that is visible to the user of the object in a valid state. The idea of getter and setter methods is very useful here. If calling code does something that does not make sense, you can always throw an exception, however, when it is possible, you should design the class such that calling code does not even have a chance to misuse it.
III. OOP trades efficiency of execution for efficiency of development. In the past, computers were more expensive than programmers, so it was worth taking a great deal of time to make code as efficient as possible. This is no longer the case. Due to the rapid drop in hardware costs, the precious resource that needs to be conserved is development time. OOP organizes code in a way that is less efficient, but provides a level of modularity that decreases the cost of development/maintenance. Therefore, the focus of the programmer should be on good design first, even if it means compromising efficiency. There are still ways to make OOP efficient, but it will never be as efficient as Procedural.
I hope this is helpful to someone.
