Variable naming conventions

Hi all,
I come from a mostly JAVA background. Big emphasis in that arena on encapsulation and modularization of code to help facilitate ease of maintenance and reuse...in theory I sometimes struggle with variable naming conventions within my ABAP code because I'm not all together certain there are any. In C or C++ I might use a derivation of Hungarian notation to name varaibles...and in JAVA I might observe certain object oriented rules regarding varaible naming...I find myself using a combination of those two protocols in my ABAP code. Does anyone have any suggestions for how I might name global and lcoal variables within my code?
regards,
Mat

SSIS variable naming conventions?

Anyone got a link for SSIS variable naming conventions?

Although this an old post, replying for readers who may be interested.
I use the following convention whenever possible -
SSIS Variable Naming Convention Based on Origin of Value

Outbound Feeds with variable naming convention.

All,
We have a openhubs that we generate every month.
Is there a way we can prefix with month & year, so the file name would look like, Month_Year_<file_name>.
So when I execute the process chain, for the same outbound file "salesvolume.csv"
for the month Jan 08, the file name is "jan08salesvolume.csv"
for the month Feb 08, the file name is "feb08salesvolume.csv"
so the file name has a variable part & a fixed path.
Variable path is based ont month-year.
Thanks

In the usage I've seen (C++), m is for "member". I'm pretty sure it's used in MFC, and it may come from the more general "Hungarian Notation" that also uses things like s for string, p for pointer (relevant in C/C++ but not Java), etc.
I think this convention is pretty unusual in Java (I've never seen it), but I imagine there are a number of people, especially C++ programmers, who do use it.

Variable naming convention..... The letter 'm'

hi experts,
I saw some people like to start their variable names with the letter lowercase 'm'. For example,
String mHappy ="";
boolean mRunning = false;
Is there a reason? What does the letter 'm' stand for?

Variable naming convention

In Java, variable names should not begin with a digit. Can any one tell me why this restriction is imposed?

BigInteger TWO = new BigInteger("2");Whythe
BigInteger 2 wasn't defined in java.math.BigIntegerI
have no idea! (Surely it is as common as 0, 1 and10
- which are defined).I tend to use 42 far more often when I have a need
for a constant value ;)
I was thinking more along the lines of a lot of things being raised to the power of 2 (especially in crypto applications, which is where I suspect BigInteger gets most of its use)
Of course, it makes no sense to define FORTY_TWO (unless you can give a decent reason... maybe your application uses 42 everywhere as opposed to the power of 2....) you are more likely to define MULTIPLIER (or something that is relevant to your app), but ZERO, ONE, TWO and TEN make sense.

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.

File name naming convention in File Adapter configuration in ID

Hi All ,
I have a query related to xml filename created in IDOC-XI-FILE scenario based on value of one of IDOC field .
The scenario is like this :
I have to send one xml file per store for material master . In this case how can I define my file name with store name in File adapter configuration in ID .
Naming convention should be
<storename>_date_masterdataname.xmlwhere store name is one of field of IDOC .
Plz help me .
Thanks in Advance
Regards
Prabhat Ranjan

Hi Prabhat,
take a look at this weblog:
/people/jayakrishnan.nair/blog/2005/06/28/dynamic-file-namexslt-mapping-with-java-enhancement-using-xi-30-sp12-part-ii
you have to specify variable substitution
(in the file adapter)
and give the path to the store name (in the variable sustitution table)
you file name schema (from the file communication channel can look like this)
%storename%_date_masterdataname.xml

Looking for best practice on naming conventions

Does anyone out there have a best practice on naming conventions that they could share.
I'm starting to find the need to create objects and associated variables and actions.
I can see this getting very messy, very quickly and would love to learn if someone has come up with a good set of guidelines that are both easy to follow and make perfect sense. (I know....what a balance to ask for!)
Thanks
Alan

Hi Alan,
Welcome to Adobe Community.
There are couple of things that you can keep in mind while naming objects.
When creating custom text caption styles, be sure to follow the correct naming conventions. Each caption style has a unique name, and you must
use this name at the beginning of each associated bitmap filename. For example, if you create a text caption style named “Brightblue,” the five
bitmap images that constitute the new style should be named as follows:
Brightblue1.bmp, an image with no callouts
Brightblue2.bmp, an image with a callout to the right or upper-right
Brightblue3.bmp, an image with a callout to the left or upper-left
Brightblue4.bmp, an image with a callout to the lower right
Brightblue5.bmp, an image with a callout to the lower left
Flash button-naming conventions
Each SWF button contains three layers: a button, an icon, and an action layer.
The SWF filename consists of the following elements:
Acronym for playback control (“pbc”)
Playback element identifier (“Btn” for button, “Bar” for bar, and so on)
Name of the button (“play”).
Hope this helps!
Thanks!

Output CSV File Naming Convention - Receiver File Adapter

Dear SAP experts,
I need help regarding my scenario.
My scenario is this, Customer will send EDI message to XI. XI will then translate the message and convert it into XML.. After, a Receiver File Adapter will receive the XML then convert it into .csv file.
I've already configured the Receiver File Adapter to convert the XML into .csv file.
But, my problem now is how will I configure to have my output .csv file has a File Naming Convention.
The output .csv file must be "CustomerName_YearMonthDate".
From the EDI message, there is indicated Sender GLN in which, each customer has its own Sender GLN.
E.g., Globus --> 200, Karstadt --> 300, Metro --> 400.
How will I configure so that I can have an output .csv file of,
If Globus sends the EDI message, the output .csv file is Globus_20080304.csv.
If Karstadt, Karstadt_20080304.csv.
If Metro, Metro_20080304.csv.
Kindly advise for a clear and complete solution.
Thank you very much for your usual support.
Fred

Hi Nisar,
My target message (XML) in the mapping is this,
- <ns0:CSV>
 - <SLI>
 <PERIO> </PERIO>
 <ILN> </ILN?
 <EAN> </EAN>
perio, iln, and ean was rooted on SLI field. and the CSV is the rootnode of the target message.
I have created a UDF on the message mapping to accomodate the output customer name, here is the codes:
String fname="";
if(GLN.equals("23456"))
fname ="Globus" +dat;
else if(GLN.equals("5678"))
fname ="Karstadt"+dat;
else if(GLN.equals("6789"))
fname ="Metro"+dat;
DynamicConfiguration conf = (DynamicConfiguration) container
 .getTransformationParameters()
 .get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create(
 "http://sap.com/xi/XI/System/File",
 "FileName");
 conf.put(key,fname );
E.g.,
Globus --> 23456 (Sender GLN)
Karstadt --> 5678 (Sender GLN)
Metro --> 6789 (Sender GLN)
This UDF i've made in the Message Mapping was mapped in the root node CSV.
Is this UDF correct?
Then on the File Receiver Configurations, here are the configs,
Transport Protocol: File System (NFS)
Message Protocol: File Content Conversion
Adapter Engine: Integration Server
File Access Parameters
Target Directory: /var/opt/gsss/sample/csv
File Name Scheme: .csv
Processing Parameters
File Construction Mode: Create

Run Operating System Command After Message Processing
Command Line: chmod 664%F
Content Conversion Parameters
Recordset Structure: SLI
SLI.addHeaderLine: 3
SLI.headerLine: PERIO;ILN;EAN
SLI.fieldSeparator: ;
SLI.endSeparator: 'nl'
Adapter Status:

Kindly advise if my configs are correct.
Thank you very much!

Checking naming convention of internal tables in code inspector

Can anyone please explain how in the code inspector can I check names of internal tables (like it_) that I use in a report program ? I know that I can specify it_ in Programming Convention -> Naming Convention->Program Global -> Data but this entry is not specific to internal tables as it also applies to variables and work areas. Apart from this is there any entry I can maintain in the Extended Naming Conventions for Programs(introduced in ECC 6.0)? Kindly reply at the earliest.

Best practices in Internal table naming convention GT , GS , LT , LS ??

Hi Gurus,
 Are GT_ , GS_ , LT_ , LS_ --- the Best practices in Internal table naming convention ????
 I have seen this naming convetions adhered in standard programs .
 What each one of the below signify
 GT_ , GS_ , LT_ , LS_ ???????
Regards
Jaman

 ABAP Techie

Hello
I use the following naming conventions:
- G = global variable
- L = local variable
- T = internal table
- S = structure
- D = field
That's how the combinations look like:
- GT_ITAB = global itab
- GS_STRUC = global structure
- GD_FIELD = global field
- LT_ITAB = local itab
- LS_STRUC = local structure
- LD_FIELD = local field
Function module parameters have to stick to the following rules:
- I = importing
- E = exporting
- [C = changing -> never used]
- IT_ITAB = imported table type (itab)
- IS_STRUC = imported structure
- ID_FIELD = imported field
- ET_ITAB = exported table type (itab)
- ES_STRUC = exported structure
- ED_FIELD = exported field
Depending on their semantics TABLES parameters look like:
- IT_ITAB = imported data
- ET_ITAB = exported data
- XT_ITAB = changing data (import & export)
Here are the conventions for FORM routine parameters:
- UT_ITAB = using itab (data are usually treated like constants; no changes will be transfer - although possible - to the calling program)
- CT_ITAB = changing itab (if it is semantically an exporting itab then one of the very
first statements in the routine is: REFRESH ct_itab. )
- US_STRUCT
- UD_FIELD
- CS_STRUCT
- CS_FIELD
Conventions for class/interface parameters:
- IT_ITAB = importing table type
- IS_STRUC = importing structure
- ID_FIELD = importing field
- ET_ITAB = exporting table type
- ES_STRUC = exporting structure
- ED_FIELD = exporting field
- RT_ITAB = returning table type
- RS_STRUC = returning structure
- RD_FIELD = returning field
Conventions for class/interface attributes:
- MT_ITAB = table type
- MS_STRUC = structure
- MD_FIELD = field
- MC_CONST = constant
Question: Are there any advantages of such elaborated naming conventions?
My answer to this question is: Yes, definitively.
I believe that the advantage of semantically differentiating TABLES parameters of function modules is quite obvious:
CALL FUNCTION 'Z_BAD_NAMING'
 TABLES
 itab1 = ...
 itab2 = ...
 itab3 = ... .
CALL FUNCTION 'Z_GOOD_NAMING'
 TABLES
 it_itab1 = ...
 et_itab2 = ...
 xt_itab3 = ... .
I also believe that my naming conventions clearly enhance readability and maintainability of my programs.

Uwe

Oracle BPEL standard, best practice and naming convention

Hi, folks,
Is there any standard or best practice associated with Oracle BPEL, regarding development, performace, what to avoid, etc? And is there any naming convention for the process, variable partner link name, etc? Similar to naming convention in writing Java code?
Thanks

Forms 6i- Good variable naming convensions

Could you suggest any good naming conventions on Forms 6i

Thanks for your time Brian,
This morning I solved,
If I tell you what it was you won't believe it.
To Oracle Forms 10g don't like that global variables comes in this way:
PACKAGE TGLOBAL IS
SEDE_AZIENDA VARCHAR2(1):= '1';
other variables
END;
but they have to be set before you call library Package, that is, set it, call library's function where you modify it !!!
TGLOBAL.SEDE_AZIENDA := '1';
CALL_FORM (......... SHARE_LIBRARY_DATA .....
Hope this helps other with same problem!!!!
Thanks again for your time, Brian and Have a good and Merry Christmas

Flatfile conversion with output file has a NAMING CONVENTION

Dear SAP experts,
I need some advise regarding my scenario.
I am converting a message into flatfile. (customized .csv)
But, the output .csv flatfile must have a naming convention.
E.g. Globus_20071020 (Customer name_YearMonthDate)
Can somebody give me ideas/inputs on what will I configure in File Receiver (FCC) in order to have an output file having a naming convention indicated above.
Or do i need additional configurations?
Please advise.
Thank you very much in advance.
Fred

Hi,
You could pass this kind of File name from mapping at runtime or
You could use the variable substitutions to create the fiel neame as per naming convention as adding date .
With reference to Variables youcould set file name as Globus_%payload.<Date>%
Pass the value in date field of payload

Custom naming convention with File Adapter

Within my BPEL process, I am using File Adapter and writing out a file. The current naming convention only all some static string with either a sequence (%SEQ%) or some sort of system timestamp. I wonder if it is possible to use some runtime data (data value within the Process Variables) as part of the file name being written out.

Hi, the file/FTP adapters support file metadata such as filename and directory to the BPEL process and exclude the payload. set the UseHeaders parameter to true in the file adapter WSDL.
*<jca:operation*
PhysicalDirectory=""
ActivationSpec="oracle.tip.adapter.file.inbound.FileActivationSpec"
PhysicalArchiveDirectory=""
DeleteFile="true"
IncludeFiles=""
PollingFrequency=""
MinimumAge="0"
OpaqueSchema="false" >
UseHeaders="true"
*</jca:operation>*
thanks.
