Advantages of OO ABAP

Hi Folks,
Can anyone please list down the 'real' advantages of OO ABAP over the conventional ABAP? Well, of course, apart from the obvious advantages of the Object Oriented concepts. I mean, when one can do everything using conventional ABAP, why should he go for OO ABAP?

Object-Oriented Programming Overview 
The concepts of Object-Oriented (OO) programming have been around for over four decades. Initially developed in the field of artificial intelligence, OO programming was embraced by Xerox as a means of developing systems that better reflected real life needs and were more user friendly. OOs popularity and sophistication has increased in the past several years as businesses are abandoning their mainframe systems and incorporating more client-server models to run their businesses and are integrating web technology as a business tool. A change in the overall pace of business has also contributed to the increased popularity of OO programming. One of the primary features of OO programming is its relative flexibility and adaptability to changing business needs.
How is OO programming different from traditional procedural programming?
Traditional programming has the following characteristics:
Functions are written sequentially, so that a change in programming can affect any code that follows it.
If a function is used multiple times in a system (i.e., a piece of code that manages the date), it is often simply cut and pasted into each program (i.e., a change log, order function, fulfillment system, etc). If a date change is needed (i.e., Y2K when the code needed to be changed to handle four numerical digits instead of two), all these pieces of code must be found, modified, and tested.
Code (sequences of computer instructions) and data (information on which the instructions operates on) are kept separate. Multiple sets of code can access and modify one set of data. One set of code may rely on data in multiple places. Multiple sets of code and data are required to work together. Changes made to any of the code sets and data sets can cause problems through out the system.
Object-Oriented programming takes a radically different approach:
Code and data are merged into one indivisible item an object (the term component has also been used to describe an object.) An object is an abstraction of a set of real-world things (for example, an object may be created around date) The object would contain all information and functionality for that thing (A date object it may contain labels like January, February, Tuesday, Wednesday. It may contain functionality that manages leap years, determines if it is a business day or a holiday, etc., See Fig. 1). Ideally, information about a particular thing should reside in only one place in a system. The information within an object is encapsulated (or hidden) from the rest of the system.
A system is composed of multiple objects (i.e., date function, reports, order processing, etc., See Fig 2). When one object needs information from another object, a request is sent asking for specific information. (for example, a report object may need to know what todays date is and will send a request to the date object) These requests are called messages and each object has an interface that manages messages.
OO programming languages include features such as class, instance, inheritance, and polymorphism that increase the power and flexibility of an object.
What are the advantages of Object-Oriented programming?
One of the main advantages of OO programming is its ease of modification; objects can easily be modified and added to a system there by reducing maintenance costs. OO programming is also considered to be better at modeling the real world than is procedural programming. It allows for more complicated and flexible interactions. OO systems are also easier for non-technical personnel to understand and easier for them to participate in the maintenance and enhancement of a system because it appeals to natural human cognition patterns.
For some systems, an OO approach can speed development time since many objects are standard across systems and can be reused. Components that manage dates, shipping, shopping carts, etc. can be purchased and easily modified for a specific system.

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)

Queries in WD ABAP

Hi all,
I have few queries:
1- What are limitation and advantages of WD ABAP?
2- How to put WD ABAP into Portal iView?
3- What is OOABAP? Which are the classes of OOABAP? Do you know how to make use of them?
Thanks
Sanket sethi

hi sanket,
advantages : [advantages|https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/02e1fa45-0801-0010-10a0-f1cf47e8c943 ]
in portal you can create a web dynpro abap iview. while creating that you need a backend system. the backed system will be the system in which your application exist.
you can mention the system and application name, then automatically your webdynpro application will be present inyour portal.
ooabap is object oriented abap whrer you will be making use of many classes. the classes available can be seen in se24.

ABAP Classes in Workflow

I am planning to use ABAP classes instead of BOR Objects in Workflow and would appreciate
1) any elaborate documentation on the use of ABAP classes in workflow (SAP help has very limited documentation)
2) comparision of using either approach with advantages of using ABAP classes over the use of BOR Objects and limitations of using ABAP classes,if any.
3) any examples of ABAP classes used in Projects
Thanks for your help.

Hi,
check the wiki, in the design and development part are listed all of Jocelyn darts blogs about OO in workflow:

Web Report - ABAP Vs JAVA engine - ABAP 10 times faster than JAVA

Guys,
I want to share what we found in our project and see if any of you have insights
into our findings.We are on NW2004S SP14 and we are moving to SP15 in a couple of weeks.We created query, developed WAD for it and executing the WAD takes for this query takes 22 secs (Vs 2 secs using ABAP) the query output has 1 million records and most of the actions we take from that point on like right click on account takes 20 secs (Vs 0 secs/instant using ABAP) , drilldown to level 4 of account hierarchy takes 58 secs (Vs 5 secs using ABAP), drilldown on cost center level 6 takes 42 secs (Vs 4 secs using ABAP), , right click on cost center takes 32 secs (Vs 3 secs using ABAP), ..etc.
Basically every action we take in the JAVA report takes an average of 28 secs.There are 9 aggregates built on the cube that are barely hit by this query but the same query performing same actions with same selections hit the aggregates many many times.The questions I have is why is ABAP so fast compared to JAVA ? What is true explanation behind this behavior ? What are the dis-advantages by using ABAP engine ? Users are loving the performance and features of ABAP while they weren't really on board with the original JAVA report (as it was slow). ABAP is sure enough 10 times faster than JAVA. Query/Query Properties are exactly the same in ABAP and JAVA.Please explain.
Cheers

Hi All,
Thanks to all you for your responses. I appreciate your time for going through my questions and coming forward to express your views.
However, I was looking for more specific "factual" answers. My question is "What does a client miss if they opt to install only ABAP based BI 7.0, as against JAVA Based BI 7.0"
thanks again.

Advantage of Being Techno-Functional

Hi,
Greetings for the day !!
Can any one explains what are the advantages of being Techno- Functional.
With Best Regards
Mamatha.B

Hi mamatha,
According to my personal opinion,
1. The only advantage is of personal satisfaction.
2. Salary wise nobody will get extra money for
   having such extra knowledge.
   (Bcos, a person is appointed in a company
    for handling his technical work of abap,
    he won't be RESPONSIBLE for customization
    and other things of functional area ;
   that responsibility will be of some other
   functional consultant)
3. Other minor advantage is that abap development
   quality and time gets efficient if we know
   a little about the functional side also.
regards,
amit m.

Seperate client for ABAP dev

Can anyone pls list out the advantages to have abap dev client seperated with the configuration client?
Thanks!

Hello Kumar
That is exactly the point why some customers have separated ABAP development and customizing into different clients on the DEV system.
The ABAP developers may disturb the work of the people doing the customizing yet customizing changes will not affect immediately the ABAP developers.
Of course customizing and ABAP development have to "meet" in the same client of the QAS system.
Another advantage of separating ABAP development and customizing into different clients is "segregation of duties": This way you can (partially) prevent ABAP developers from doing customizing.
Regards
Uwe
PS: I have seen this kind of segregation in the system landscape of one of the biggest customers of SAP Switzerland.

ABAP Dataflow or Regular Dataflow?

We can extract data from ECC system using BODS by creating regular dataflow as well as ABAP dataflow.
Are there any guidelines from SAP that we should use ABAP dataflow only?
What is advantage of using ABAP dataflow over regular dataflow? Any performance improvement?

Hi Sagar,
Regular Dataflow:
Reads data from SAP applications using regular data flows and supports tables (for small data sets only) and extractors.
ABAP Dataflow : Reads data from SAP applications using ABAP data flows and supports tables, hierarchies, extractors, and functions with scalar arguments, good for .
Based on the number of records you mentioned, I would say ABAP is your better option. Because for large amounts of data performance is generally better when you extract data using ABAP data flow.
(note: if you want to know limitations/Disadvantages related to ABAP dataflow please check this link http://www.forumtopics.com/busobj/viewtopic.php?t=210395&view=next&sid=443a727d4201219c16aba7f5e786c231
hope you understand and its help you..

Security interview questions - some fun to tickle your brain.

Hello gurus,
I know that posting interview question series are not allowed if the person has not put in any effort, but I have and folks seem to want to practice a bit sometimes so I take the liberty of creating a central one.
Tackle one or all of them to test your knowledge.
There are no model answers.
If you want to suggest additional ones, then please contact me.
The rules
Flaming of answers is allowed.
Funny answers earn a beer (or cup of tea).
There are no points.
1) When PFCG proposes 3 activities but you only want 2, how do you fix this?
2) What is the use of transaction PFUD at midnight?
3) Is PFUD needed when saving in SU01 and does the user need to logoff and on again after changes?
4) How are web services represented in authorizations of users who are not logged on?
5) How do you force a user to change their password and on which grounds would you do so?
6) What is the difference between SU24 and SU22? What is "orginal data" in SU22 context?
7) When an authorization check on S_BTCH_JOB fails, what happens?
8) Can you have more than one set of org-level values in one role?
9) Should RFC users have SAP_NEW and why?
10) What is an X-glueb command and where do you use it in SAP security?
11) What is the disadvantage of searching for AUTHORITY-CHECK statements in ABAP OO coding and how does SU53 deal with this?
12) In which tables can you make customizing settings for the security administration and name one example of such a setting which is usefull but not SAP default?
13) Can you use the information in SM20N to build roles and how?
14) If the system raises a message that authorizations are missing but you have SAP_ALL, what do you do?
15) Name any one security related SAP note and explain it's purpose or solution.
16) What are the two primary differences between a SAML token profile and a SAP logon ticket?
17) Where do you configure the local and global settings of the CUA and what are the consequences of inconsistent settings?
18) If you have users in different systems with different user ID's for the same person, what are your options to manage their authorizations centrally?
19) Explain the use of the TMSSUP* RFC destinations and the importance of the domain controller?
20) Why should you delete SAP_NEW profile and which transaction should you use before doing so?
To be continued...

I have one year experience in SAP Security and only two in Basis, so flame on......... I swear I didn't use google or any of my systems for reference! 
1) When PFCG proposes 3 activities but you only want 2, how do you fix this? Best answer is to modify your su24 data. 
2) What is the use of transaction PFUD at midnight? removes invalid profiles from user records 
3)Is PFUD needed when saving in SU01 and does the user need to logoff and on again after changes? PFUD is not needed and the user needs to log off and back on again 
4)How are web services represented in authorizations of users who are not logged on? ?? 
5)How do you force a user to change their password and on which grounds would you do so? SU01 -> Logon Data tab -> Deactivate password. I am not sure what grounds this would be necessary. I have never had to use it. 
6)What is the difference between SU24 and SU22? What is "orginal data" in SU22 context? SU22 you maintain authorization objects???? Su24 you maintain which authorization objects are checked in transactions and maintain the authorization proposals. 
7)When an authorization check on S_BTCH_JOB fails, what happens? "You do not have authorization to perform whatever operation you are trying to perform." message. HAHA 
8)Can you have more than one set of org-level values in one role? I might be misinterpreting this question. But yes. Depending on the transactions inserted into the role menu, you could have more than one org level to maintain. Purchasing Org and Plant, Sales Org and Sales Division..... 
9)Should RFC users have SAP_NEW and why? No. Just insert the transactions and necessary authorization objects into a role. S_RFC for one. 
10) What is an X-glueb command and where do you use it in SAP security? ??? 
11) What is the disadvantage of searching for AUTHORITY-CHECK statements in ABAP OO coding and how does SU53 deal with this? Disadvantage? I can think of an advantage. My ABAPer shows me his programs and we work out what authority checks should be performed. 
12) In which tables can you make customizing settings for the security administration and name one example of such a setting which is usefull but not SAP default? ??? 
13) Can you use the information in SM20N to build roles and how? You could, I guess. Not a good practice though. Build roles based on business processes. 
14) If the system raises a message that authorizations are missing but you have SAP_ALL, what do you do? Regenerate SAP_ALL which reconciles new authorization objects from SAP_NEW 
15) Name any one security related SAP note and explain it's purpose or solution. Don't know the number off hand, but I was looking at it yesterday. Program Z_DEL_AGR to allow deletion of more than one role at a time. There is no mechanism in SAP to achieve this currently. 
16) What are the two primary difference between a SAML token profile and a Logon ticket in SAP? ??? I know what these are but have no experience with it.

Accessing tables from different schema in CDS and AMDP

Hi All,
We are working on a HANA system which has several schema replicated from SAP R/3/Non SAP systems. We have BW 7.4 SP9 deployed on the same system and accessing the HANA views using latest BW virtual objects such as Open ODS , Composite providers etc.
We are also using the BW system for few ABAP based data processing developments. We are currently accessing HANA views in ABAP programs by creating dictionary views based on external HANA views.
We would like to however use recent possibilities of CDS and AMDP for better life cycle management of ABAP based solutions. The open SAP course on this subject was of very good help. Thanks a lot "open SAP team" for that. I would however have few open questions,
As I understand AMDP gives us full flexibility of writing sql procedures within ABAP development environment, but can we access tables from different schema into AMDP code. If yes, then sample code would help.
If the answer of first question is yes, then how do we manage transports between development and production systems where the schema names would be different. Currently in open HANA developments, such transport is manged using Schema mapping.
Can I also use different schema tables in CDS views.
We are updating few tables in ABAP dictionary after applying processing logic in ABAP program as detailed in step 1. With the new approach using AMDP, can we directly update database schema tables which will give us an optimization advantage.
New ABAP HANA program interfaces are quite promising and we would like to use them to optimize many data intensive applications.
Thanks & Regards,
Anil

Hi Anil,
I can only answer 1. and 2. (and would be interested into 3. as well):
1.
Yes you can access tables from a different schema and also HANA views. In this case no 'using' is needed.
Examples:
    RESULT = SELECT
    FROM
          "SAP_ECC"."T441V" AS t,
          "_SYS_BIC"."tmp.package/AFPO" AS a.
    WHERE ...
2. In this case, if you need schema mapping: You could use HANA (projection) views which just forward to a different schema, also see example.
Best regards,
Christoph

Hi David,
This is regarding SET & GET Parameters.
SAP allows you to make use of SPA/GPA technique to fill the input fields of a called transaction with data from the calling program.SPA/GPA parameters are values that the system stores in the global, user-specific SAP memory. SAP memory allows you to pass values between programs. A user can access the values stored in the SAP memory during one terminal session for all parallel sessions. Each SPA/GPA parameter is identified by a 20-character code. You can maintain them in the Repository Browser in the ABAP Workbench. The values in SPA/GPA parameters are user-specific.
ABAP programs can access the parameters using the SET PARAMETER and GET PARAMETER statements.
To fill one, use:
SET PARAMETER ID <pid> FIELD <f>.
This statement saves the contents of field <f> under the ID <pid> in the SAP memory. The code <pid> can be up to 20 characters long. If there was already a value stored under <pid>, this statement overwrites it. If the ID <pid> does not exist, double-click <pid> in the ABAP Editor to create a new parameter object.
To read an SPA/GPA parameter, use:
GET PARAMETER ID <pid> FIELD <f>.
This statement fills the value stored under the ID <pid> into the variable <f>. If the system does not find a value for <pid> in the SAP memory, it sets SY-SUBRC to 4, otherwise to 0.
To fill the initial screen of a program using SPA/GPA parameters, you normally only need the SET PARAMETER statement.
The relevant fields must each be linked to an SPA/GPA parameter.
On a selection screen, you link fields to parameters using the MEMORY ID addition in the PARAMETERS or SELECT-OPTIONS statement. If you specify an SPA/GPA parameter ID when you declare a parameter or selection option, the corresponding input field is linked to that input field.
On a screen, you link fields to parameters in the Screen Painter. When you define the field attributes of an input field, you can enter the name of an SPA/GPA parameter in the Parameter ID field in the screen attributes. The SET parameter and GET parameter checkboxes allow you to specify whether the field should be filled from the corresponding SPA/GPA parameter in the PBO event, and whether the SPA/GPA parameter should be filled with the value from the screen in the PAI event.
When an input field is linked to an SPA/GPA parameter, it is initialized with the current value of the parameter each time the screen is displayed. This is the reason why fields on screens in the R/3 System often already contain values when you call them more than once.
When you call programs, you can use SPA/GPA parameters with no additional programming overhead if, for example, you need to fill obligatory fields on the initial screen of the called program. The system simply transfers the values from the parameters into the input fields of the called program.
However, you can control the contents of the parameters from your program by using the SET PARAMETER statement before the actual program call. This technique is particularly useful if you want to skip the initial screen of the called program and that screen contains obligatory fields.
If you want to set SPA/GPA parameters before a program call, you need to know which parameters are linked to which fields on the initial screen. A simple way of doing this is to start the program that you want to call, place the cursor on the input fields, and choose F1 followed by Technical info. The Parameter ID field contains the name of the corresponding SPA/GPA parameter. Alternatively, you can look at the screen definition in the Screen Painter.
The SPA/GPA parameter for the input field Company has the ID CAR. Use this method to find the IDs CON, DAY, and BOK for the other input fields.
The following executable program is connected to the logical database F1S and calls an update transaction:
REPORT BOOKINGS NO STANDARD PAGE HEADING.
TABLES SBOOK.
START-OF-SELECTION.
WRITE: 'Select a booking',
SKIP.
GET SBOOK.
WRITE: SBOOK-CARRID, SBOOK-CONNID,
SBOOK-FLDATE, SBOOK-BOOKID.
HIDE: SBOOK-CARRID, SBOOK-CONNID,
SBOOK-FLDATE, SBOOK-BOOKID.
AT LINE-SELECTION.
SET PARAMETER ID: 'CAR' FIELD SBOOK-CARRID,
'CON' FIELD SBOOK-CONNID,
'DAY' FIELD SBOOK-FLDATE,
'BOK' FIELD SBOOK-BOOKID.
CALL TRANSACTION 'BOOK'.
The basic list of the program shows fields from the database table SBOOK according to the user entries on the selection screen. These data are also stored in the HIDE areas of each line.
Reward If useful.

Chitra

3. Is it mandatory to know JAVA language to sustain with NW technologies? or ABAP itself is enough ?
Its all depend in which stack you want to fit. If you want to go into EP, then JAVA is must. In XI having knowledge of JAVA will be highly useful and in other Netweaver stack it will be an added advantage. Anyhow ABAP is not enough to sustain with NW technologies.

4. If JAVA is essential ...where to start with ?
Core JAVA, J2EE in full is needed for Netweaver. As where to start is concern you can start with core JAVA and consequencely go thorugh J2EE.
I hope this will help you out.
