Is there naming conventions for variables, itabs?

Hi!
Is there an ad hoc naming convention standard for writing ABAP programs?
What prefixes, suffixes, etc. I should use when defining selection options, variables, internal tables, etc.
Thank you!

Hi,
We have to follow the naming conventions according to the client's coding standards.
For example
My present client.
I am following the conventions as follows:
Variables: v_variablename,
Constants: c_contant,
Select-options: S_selopt,
Internal tables: T_
Work Areas: K_
Etc.
Reward me if it is useful.

PO Naming Convention for specific company code

Hi experts!
Is there any way to know this PO naming convention is belongs to which company code?
For eg: PO naming convention starts with 600*******.
How will i know which company code is using the naming convention for their purchase order?
Please help.
Thanks.

Hi Crystal,
Naming convention is based on document type not company code :
Refer the below customsing path:

Can anyone tell me the naming conventions for PSa tables

hi all,
After the data is loaded into the psa. how to look at the records that are there in psa. And can anyone tell me the naming conventions for psa tables.
like BIC/????
thanxs in advance
regds
hari

Hi Hari,
You want to know the naming convention of PSA table. For that there is a simple technique try this.
Go to - T code SE11
In the database table check box give /BI* and click search
next window in the Description Text box give the r data source name(master) like
YIO_ID_ATTR which is assigned to infosource. then click OK.
then you get the psa table structure.
You can take structure and check in the T code SE 11
Hope this is fine.

Naming convention for packages and classes

Hi all,
Is there any naming conventions for packages and classes which uses a design pattern ?. If yes what are the conventions used for business delegate,session facade, service locator,DAO and any other patterns.
rgds
Anto Paul

Hi,
that is a good question and one we have considered also. We dont yet cover the naming conventions for classes based on patterns but maybe will in the future. Currently, in the blueprints apps we tend to do some things like naminga class
-AccountDAO etc for DAOs
-For servicelocator we have a class called ServiceLocator viewable at https://adventurebuilder.dev.java.net/source/browse/adventurebuilder/ws/components/servicelocator/src/java/com/sun/j2ee/blueprints/servicelocator/web/ServiceLocator.java?rev=1.4&content-type=text/vnd.viewcvs-markup
-for session facade, its a bit trickier since the name is so long and we cant add "SessionFacade" to the end of each facade class. I think in general we put "Facade" in the name, usually near the end
-For Business Delegat, again it seems too long to add to each class name. So in the past we have added
a "BD" to the names of the delegates. Some examples are at http://java.sun.com/blueprints/patterns/BusinessDelegate.html
-For transfer objects we usually add a TO to the end of the name. Some examples at http://java.sun.com/blueprints/patterns/TransferObject.html
Seems like something we could get a bit more consistent about.
hope that helps,
Sean

Code Inspector - Naming conventions &mExtended Naming conventions for Progs

Hi experts,
I had a look into the naming conventions enforced by 'DEFAULT' variant of code inspector (SCI).
the relevant categories are: "Naming Conventions", and "Extended Naming conventions for Programs" under "Programing conventions".
in the "Extended Naming conventions for Programs" category, for functions, (applicable while calling the functions) it says,
importing parameter : I[:type:]_
exporting parameter : E[:type:]_
changing parameter : C[:type:]_
tables parameter : T[:type:]_
but in the "naming conventions" category, for functions (applicable while defining the functions), it says,
importing parameter : P_*
exporting parameter : P_*
changing parameter : P_*
tables parameter : P_*
I felt, while defining the function too, its better to have beginning with I_, E_, C_ or T_ instead of P_
is the 'DEFAULT' variant of code inspector is provided and recommended by SAP?
for easier maintenance and clearer understanding, which naming convention is more suitable, or is there any official guidelines released by SAP for ABAP developers.
appreciate the opinions from experienced abap developers.
thanks,
Madhu_1980

Frank,
Thanks for your answer.
But what about Entity Objects, View Objects, View Links, and Application Modules.
I would like my developers to have an easy way to name them and also find them via intellisense.
So I was thinking in naming them the following way :
Entity Objects :
EO_Employee
EO_Department
View Objects :
VO_Employees
VO_Departments
View Links :
VL_EmployeesToDepartments
Application Module :
AM_HRService
However the use of "_" is not so "Java naming oriented".
So other alternatives would be:
1. take the "_" :
1.1 EOEmployee (I don't like the fact of having 3 capital letters together).
1.2 EoEmployee (I don't like the fact of having Entity Object with a lowercase "o").
2. Use the prefix at the end, but this way I loose the intellisense feature I want:
ex: EmployeeEO
Which naming approach are you using for big projects ?
Thanks,
Claudio.

Naming conventions for CMS tracks

Hello all,
i want to setup CMS for XI transports and create some naming conventions for track id, track name and track description. I studied the howto guides, help.sap.com and searched the forum but i still have no satisfying answer for some questions.
Repository Transports
As i read on a blog it would be a good idea to create separate tracks for each SWCV. To think about an unique name for track id and track name it's worth knowing if one SWCV can be assigned to more than one track. If not the SWCV would be sufficient to identify the track. Otherwise i have to add some prefix/suffix to make the track unique.
Directory Transports
For Integration Directory track there is only one SWC on CMS available, SAP-INTDIR. Is it possible to create two tracks on one CMS with SAP-INTDIR for supplying two independent XI lines with directory content? For example one track for XD1 -> XQ1 -> XP1 and another for XD2 -> XQ2 -> XP2. If so the SWC alone is again not sufficient to identify the track.
If anybody has already thought about naming track id and track name i would be pleased to hear about your approach.
Kind regards,
Frank Opitz

Powershell naming conventions for functions

There is a lot of information about the Verb-Noun naming convention for cmdlets. I am trying to understand what the recommendation / best practice is for naming functions. Personally, I like the idea that if I see Verb-Noun, I know it's
a cmdlet, and it supports the standard parameters. However, I'm not sure I see the entire picture.
Thanks!

There are as many opinions around this as there are people. TechNet has some good recommendations for naming conventions, but you should adopt whatever standard you are most comfortable with. In the end it doesn't much matter which convention
you adopt, as long as you stick to it and keep it consistent. Most corporate code doesn't get outside or shared with other businesses and vendors, so the whole purpose of standards and conventions is to keep things straight for YOUR people. As
long as you consistently apply your conventions, it doesn't matter.
I trust that answers your question...
Thanks

Whats most common naming convention for MP3s (what does iTunes store use?)

Trying to organise all my tags and music.
I am using iTunes and some other tag (tag%rename) WMP etc, as some seem to not show all the tgs of other programs)
However what is the generalised, most common naming convention for MP3 files?
ie. track no, Album, artist etc.
Also Ive never bought music from iTunes store yet, only got podcasts and stuff, but when you do , what is the filename convention they use please?
cheers
Mac OS X (10.5) iMac 20" 2Ghz (1st ever Mac Comp)

iTunes has no automatic tag look up function for anything other than CDs (through GraceNote). I import a lot of mp3s (legally obtained) that need tweaking. Also, GraceNote doesn't provide lyrics. If I just need to edit a couple of tracks, the iTunes interface is fine. But for bulk adding of artwork or searching for release dates or lyrics, I use MpFreaker. I find it works best if you do small batches and keep an eye on what it comes up with. Sometimes, well, rarely, it's way off base.
There may be better utilities out there but MpFreaker was recommended to me by someone I trust who spends a lot of time reviewing such things and it works for me so I haven't looked for anything else. You might find more reviews of other software at www.ilounge.com
Best of luck.

Implement a technical naming convention for queries depending on user

Hello,
I'd like to implement a technical naming convention for queries depending on the user, because I want to make sure that the users are taking care of the naming conventions.
For example a user defines a query and would like to save this query.
During the save process he should only have the possibility to save the query with the name C_Name-of-Infoprovider_Text.
The C should be unchageable for the user.
The Name-of-Infoprovider should set automatically (if possible).
The Text could be defined by the user.
Another user would have this naming convention: X_Name-of-Infoprovider_Text
Is there a possibility to implement such a function? (or just a part of this)
Thank you.

Thank you for your answer!
Your answer helped me to implement a part of the naming conventions.
Maybe some as an idea to implement the rest of the naming convention.
--> Technical query name depending on technical name of the InfoProvider.
Has anyone an idea?

Oracle Recomanded Naming Conventions for SOA

Hi,
We are working on a 12i implementation project using SOA (BPEL) for interface development and Oracle Data Integrator for conversion. Could you please let us know about oracle recomanded naming conventions for
1. Adapter Service
2. Adapter Connection Factories
3. Routing Services
4. XSD Files
5. XSL Transformation Files
6. ...etc
Is there any oracle corporation provided naming conventions document on these? If so please let us know. Your quick help would be highly appreciated.
Regards

If the names are meaningful (which will depend on what objects are in the different schemas) and the underlying architecture is reasonable, then the naming convention would be a good practice.
- How do the objects in the ABC schema relate to the objects in the ABC_ADMIN schema?
- What, exactly, does the _ADMIN suffix indicate?
My unfounded guess is that you have two related schemas because you're creating one schema that owns the objects and another schema that has restricted access to those objects (ideally just via procedures, functions, and views) for applications to use to log in. If that's the case, it's not obvious to me which of ABC and ABC_ADMIN would own the objects for the ABC application. But if you're actually separating the objects for other reasons, then _ADMIN may make perfect sense.

Naming convention for Swing components?

What are the official naming conventions for Swing components such as JButton, JFileChooser and so on?
I know that "btn" is used for JButton variables. But where is a official list for all the prefixes?

Well, if you unpack src.jar and consult the component classes you'll find how they set up their names.
You can also call setName yourself to set a different name.

New query naming convention for Queries in Prod (Y-queries)

Hi,
We are trying to implement a new naming convention for ad-hoc queries in production. Currently we do not allow queries to be created in Production. Users would like to create Y-queries in production. Using security we can allow users to create Y-queries, without being able to create or change Z-queries (z's are official queries).
Can we also allow users to create Y-Calculated or restricted key figures? Is there anything else we need to be aware of?
Thanks,
Mike

Hi Mike,
When we create Y queries in production, we have trouble using Z calculated key figures in those queries. When we try to save the Y query (containing Z calculated key figures) we receive an error "The query could not be saved due to a problem in the transport". I believe it is due to the fact that our Z calculated key figures are transported. To work around this, we recreate the calculated key figure and save it as a Y key figure and then save the query. Not sure if this will happen to you as well, but it may be worth testing to determine if you will need to grant access for your users to create calculated key figures.
Regards,
Charla

Naming conventions for Members

Hi,
Is there any naming convention for dimension members? To be more specific, can I create a member called 'Current' or would this affect the keyword current used for reporting and hence not allowed?
Shehzad

Hi,
I have an application in which there is a member called 'Current' in the Version dimension. Whenever I deploy the application this member is never created in the first iteration. If I redeploy the application and refresh the dimensions, this member is then created.
Now in a further enhancement of the application, there are some Account members that have a reference to this member in their Member Formula's. Since in the first iteration this member isn't created, the dependent members also fail with an error and the application doesn't deploy.
Is there a fix around for this?
Shehzad
Off the top of my head, I imagine that I can deploy the previous version. Redeploy it to make sure 'Current' is created. Update the dimension library with the enhanced version of the application and redeploy again. This seems like a really cumbersome process, so I would love to know how I can ensure that this member gets created in the first go!
