ABAP Develoment Guidelines

Hi Colleagues,
I am a SAP BI consultant working for a small company. I would to put in place ABAP development guidelines.
And as I am not an ABAP expert, I would like to have your input on this.
Could somebody provide me some ABAP development guidelines ?
Thanks,

In this lecture of the week you can find the guidelines

ABAP Programming Guidelines not showing in ABAP Keyword Documentation

We are currently in the process of upgrading to Netweaver 7.0 EhP2
I have seen mentioned that the ABAP Keyword Documentation and ABAP Examples are now all provided in an improved ABAPDOCU transaction. In addition, the ABAPDOCU transaction is meant to also have a section on ABAP Programming Guidelines.
I have seen a screen example of what the ABAPDOCU screen now looks like (as shown in the mockup below). Our ABAPDOCU screen looks very similar except that there is no node for ABAP Programming Guidelines.
That is an area that I would like to have a closer look at. Have we missed something. Is this available as part of the standard 7.0 EhP2 install or does it need to be installed separately (or perhaps is this only available in a higher EhP). I've tried finding further information on this option but have not been able to come across anything. Does anyone know what would be involved (or if it is possible) to make this available in EhP2

Hi Greg,
When [searching|http://help.sap.com/search/sap_trex.jsp] the [documentation for NW 7.0.2|http://help.sap.com/nw702/] for ABAP keyword there are several documents that mention how you can find more details about ABAP keywords. For example, [Data Consistency|http://help.sap.com/saphelp_nw70ehp2/helpdata/en/41/7af4b6a79e11d1950f0000e82de14a/frameset.htm] mentions a menu in the ABAP Editor, and [New Features in Web Dynpro ABAP for Enhancement Package 2 (EhP2)|http://help.sap.com/saphelp_nw70ehp2/helpdata/en/54/07ec96bd5a4764be4996fff231b4de/frameset.htm] mentions the ABAPHELP transaction.
I suppose you could try to find if the documentation you need is installed on your system. Perhaps the [how do I Install SAP Document CD and SAP Library|how do I Install SAP Document CD and SAP Library; thread might be of help.

ABAP Standard & Guidelines OO vs Procedural

Hi all -
In Blueprint phase of new SAP implementation and am creating ABAP Standard & Guidelines document. I am split on whether to enforce use of object-oriented versus procedural programming (as per Blumenthal & Keller). Seems to me that even on ECC 7.0, I am pressed to find reports using OO approach. If I choose to enforce OO approach, there seems to be a general lack of real world examples that I can create templates from which to accelerate development. There are plenty of "old style" reports to use as the basis of custom development however. Development (as usual) will be on a very tight timeline and therefore I believe OO technics may be slower due to learning curve, etc.
Any advice would be appreciated.
Thanks,
Pat

Pat, I have to agree about the 15 pages vs 50 pages. You would get a better response if the guidelines weren't so many and rigid. I do agree, of course, that there should be some. The reason why I say this is, because I am the only developer at my company, which means, I pretty much do what I want when it comes to design and how the programs are written. That said, I have developed my own guidelines(not written, just in my head) as to how to write certain programs. But if we had more developers, I would want them to adhere to certain guidelines(not all of mine, but some) so that our programs are consistant in design and more maintainable.
Really, since I've said all of the previous, I really have no right giving you advice about guidelines and standards as I do not follow any but my own.
It also depends on the type of developers that you have in your shop. If you have a bunch of old guys(no offense anyone) that are set in there ways, you may have some resistance, if you got some new guys, that are just starting out in ABAP, they will be much easier to mold with standards and guidelines.

Rich Heilman

ABAP development guidelines for BW

Does anyone know of any paper on abap guidelines/best practises in BW ?
Thank you,

Hi RPD,
I'm not sure if there are any best practices for ABAP specifically for BW. If there are any, then I suppose the guys in the BW forum will know it.

ABAP RICEF Estimating Guidelines

Hi all -
I am looking for ABAP estimating guidelines for RICEF development. Typically in the past I have categorized development objects as low, medium, high very high complexity and attached total days effort to each. If anyone has formalized documentation on the approach they use or the ASAP approach, I would appreciate a copy to refine my methodology.
Thanks,
Pat

Hi Pat,
Sorry, I would never commit to any estimate - not even the "softest" one - unless I had some level of understanding. I got burnt many times in the past: once you give a rough estimate they will come back and nail you if you exceed it.
I give you a perfect example: I worked on a project to implement R/3 at a manufacturing company - a new acquisition of our existing client who at this point was already up and running on SAP.
Based on an assessment that some "know-it-all" director did during the first visit to the new plant, there was literally no development effort involved at all. I finally insisted to go there for one day myself to make sure that this is correct. I found out that part of the contract was to "replace an existing Inventory Management System" with SAP. What this genius did, was to assume that the IV system's functionality can be covered by SAP's IM module; what he didn't do, was to find out what this legacy system actually really did: it was a full-blown production MIS system, tailored especially to the business needs of the company. We (development team) ended up working 36 days straight over the Christmas holidays, averaging 65h a week to build dozens of interfaces, add-ons etc. to get this to work.
I guess this is not really what you are looking for, but that's how I would and do handle estimates: get at least a high-level overview on every single development object before I come up with any number.
Thanks,
Guenther

Logical Database vs Database tables

Hi,
To extract some information in a report program, currently we are making use of a Logical Database . But we see that the performance is very poor and we believe , a direct read from the database tables should improve the performance.
We are looking for some supporting documents which confirms the same. (A direct read from the database tables gives better performance than reading from a Logical database). Any points will be highly appreciated.
Thanks a lot.
Regards,
Suganya

Hi,
As per the recent ABAP Programing Guidelines, the use of the Logical Database is highly discouraged.
You can have a look at the guidelines at the following link :
http://www.sap-press.com/product.cfm?account=&product=H3072&shoppingcart=003
Th official Programing Guide cna be locate at

Hope this helps.

Call Method using RFC -

Hi,
is it possible to call a method of a class from a remote system without using a RFC enabled function module?
I mean without calling a class method instantiated in a function module.
Michael

Unfortunately no. This is one of the areas not covered by ABAP OO.
The list of missing features (as of 7.0 ehp 2) is outlined in "Official ABAP Programming Guidelines" book:
- remote method invocation as a replacement for rfc
- replacement for update FMs (CALL FUNCTIOn IN UPDATE TASK)
- replacement for call of subroutines during COMMIT WORK and ROLLBACK
- OO handling of classic screens
- dynamic generation of programs (GENERATE SUBROUTINE POOL)
- direct support of background processing (SUBMIT VIA JOB)

PO message issue above certain PO value

Hi,
I am thinking about a value-related PO message issue. Is this possible by default?
One example:
POs are to be issued via fax, no problem. But if PO value exceeds e.g. 100.000u20AC, the PO should also be issued via e-mail or printout to another (internal) party, just as a notice that this high-value PO has been sent out.
Is there any possibility to implement this w/o big efforts?

by standard setting there is no possibility.
It is possibe with help of ABAP develoment.
No Big effort required

REG: Obsolete statements in SLIN ecc 5.0

Hi all,
When i am executing the ABAP EPC for obsolete statements.(with Also display Hidden Messages)
I get the 2 Obsolete statements and as following :
      Program: ZXXXXX     Row:    652
The current ABAP command is obsolete and problematic, especially so in ABAP
Objects
An explicit work area is necessary in the OO context. Use "APPEND wa TO S_WERKS
[SORTED BY]".
(The message can be hidden with "#EC *)
Program: ZXXXXX     Row:   2558
The current ABAP command is obsolete and problematic, especially so in ABAP
Objects
At "LOOP AT itab", one of the additions "INTO", "ASSIGNING", or "TRANSPORTING NO
FIELDS" is required. in the OO context.
(The message can be hidden with "#EC *)
Though i put the "#EC after above variable still i can see it in the SLIN overview.
Pls help me to hide these Obsolete statements.
Thanks and Regards
Srikanth.P

Lest you find yourself labelled as "out of date" or "obsolete", perhaps you could spend a little time to bring your coding practices up to the state of the product. A LOT of things used in ABAP within my 12 years are now obsolete. For instance, the "Official ABAP Programming Guidelines" by SAP Press, written by Drs. Thummel and Keller, describes FORM....ENDFORM and REFRESH as obsolete.
In current versions, we loop at ...assgining <Field-symbol> or into structure....
We do read table into structure or assigning <field-symbol> or (where possible) transporting no fields.
We don't have tables with header rows, since those can't be used in OO.
We don't use REFRESH, we use CLEAR tabname[].
In OO, we use the SoC, software layering concepts, with GUI, Application and Persistence level Class definitions and implementations.
We used class-based exception handling where possible to avoid abends which are, of course, detrimental to our users' experiences.
etc.

Static Classes/Methods vs Objects/Instance Classes/Methods?

Hi,
I am reading "Official ABAP Programming Guidelines" book. And I saw the rule:
Rule 5.3: Do Not Use Static Classes
Preferably use objects instead of static classes. If you don't want to have a multiple instantiation, you can use singletons.
I needed to create a global class and some methods under that. And there is no any object-oriented design idea exists. Instead of creating a function group/modules, I have decided to create a global class (even is a abstract class) and some static methods.So I directly use these static methods by using zcl_class=>method().
But the rule above says "Don't use static classes/methods, always use instance methods if even there is no object-oriented design".
The book listed several reasons, one for example
1-) Static classes are implicitly loaded first time they are used, and the corresponding static constructor -of available- is executed. They remain in the memory as long as the current internal session exists. Therefore, if you use static classes, you cannot actually control the time of initialization and have no option to release the memory.
So if I use a static class/method in a subroutine, it will be loaded into memory and it will stay in the memory till I close the program.
But if I use instance class/method, I can CREATE OBJECT lo_object TYPE REF TO zcl_class then use method lo_object->method(), then I can FREE lo_object to delete from the memory. Is my understanding correct?
Any idea? What do you prefer Static Class OR Object/Instance Class?
Thanks in advance.
Tuncay

@Naimesh Patel
So you recommend to use instance class/methods even though method logic is just self-executable. Right?
<h3>Example:</h3>
<h4>Instance option</h4>
CLASS zcl_class DEFINITION.
METHODS add_1 IMPORTING i_input type i EXPORTING e_output type i.
METHODS subtract_1 IMPORTING i_input type i EXPORTING e_output type i.
ENDCLASS
CLASS zcl_class IMPLEMENTATION.
METHOD add_1.
    e_output = i_input + 1.
ENDMETHOD.
METHOD subtract_1.
    e_output = i_input - 1.
ENDMETHOD.
ENDCLASS
CREATE OBJECT lo_object.
lo_object->add_1(
exporting i_input = 1
importing e_output = lv_output ).
lo_object->subtract_1(
exporting i_input = 2
importing e_output = lv_output2 ).
<h4>Static option</h4>
CLASS zcl_class DEFINITION.
CLASS-METHODS add_1 IMPORTING i_input type i EXPORTING e_output type i.
CLASS-METHODS subtract_1 IMPORTING i_input type i EXPORTING e_output type i.
ENDCLASS
CLASS zcl_class IMPLEMENTATION.
METHOD add_1.
    e_output = i_input + 1.
ENDMETHOD.
METHOD subtract_1.
    e_output = i_input - 1.
ENDMETHOD.
ENDCLASS
CREATE OBJECT lo_object.
lo_object->add_1(
zcl_class=>add_1(
exporting i_input = 1
importing e_output = lv_output ).
lo_object->subtract_1(
zcl_class=>subtract_1(
exporting i_input = 2
importing e_output = lv_output2 ).
So which option is best? Pros and Cons?

BOR vs. CLASS

Hi to everybody,
I'm developping an application to manage authorization requests.
I began it using BOR, for the reason that i'll manage different status creating them by SAP Workflow.
When I started with the application, we use the BOR FORMABSENC like an example, but while I were developping I found out several problems and I decided to create it with CLASS and SAP Work.
I would like to know what's the difference between BOR or Class, which of both options you recommend me and why you've decided on it.
I´m looking forward to a response soon.
Thank you.
Nicocer.

hello,
It is always good to adapt to object oriented approach for all sort of ABAP development. Using BOR is the conventional style of build. You will have better control on the program flow and design using OOABAP. Read some demo chapters available on internet of SAP press book "official abap programming guidelines" for your answer.
Thanks

Has anyone written a BSP development standards document?.

I was wondering if anyone had written any devlopement standards and was willing to share them. With so much code involved I guess there must be some standards.
I've got to put together a standards document for BSP, but I would rather not start from the beginning, given the choice.
Best regards
Jas

Hi Jas,
have you seen this book:
[Official ABAP Programming Guidelines |http://www.sap-press.de/katalog/buecher/titel/gp/titelID-2093]
It is not about BSP but lots of things in this books can be used.
