Reg: Standards to be followed while developing a smartform

Hi,
I am preparing a document on " Standards to be followed while developing a smartform" for my company. Could anyone send documents related to my subject or guide me where can I find one, it will be very helpful for me.

Hi Prabu,
You can try something like this.
Layout Sets:
Layout sets may have names up to 30 characters in length, using the format
Zx(2-30)
Example: ZNEWLAYOUT New layout is the layout set name.
If you copy a standard layout set, insert a Z as the first character .If the standard layout set already has 30 characters replace the first character with Z.
Styles:
Style may have names up to 30 characters in length, using the format
Zx(2-30).
Example: ZSTYLE.
If you copy a standard layout set, insert a Z as the first character .If the standard layout set already has 30 characters replace the first character with Z.
Standard Text IDs:
Standard text IDs may have name up to 4 characters in length using the format
Znnn.
Example: ZTXH.
If you copy a standard layout set, insert a Z as the first character .If the standard layout set already has 4 characters replace the first character with Z.
Standard Text Names:
Standard text names may have names up to 32 characters in length using the format Zx(2-32).
Example: ZSTANDARDTEXT.
If you copy a SAP standard text name, insert a Z as the first character .If the SAP standard text name set already has 32 characters replace the first character with Z.

Determining performance while development

Dear all,
We are creating a new report that selects data from the BSEG and two other tables. There is very little data available on the development server. In such a situation, will the results of SQL trace run on development server be indicative of how the report will perform in production.
We intend to run several tests using joins/views. Can we say that the best performance case here will result in best performance case when the tables have a huge data?
Thanks,
Michael

Yes, And that is the reason we should follow proper performance condition while writing the code itself.
As a developer you should know which select query, which kind of data declartion, condition checks, caluclations in the report can increase the performance of the program.
Some time even if you write every thing good wrt performance conditions, that may creates problem at higher level system. Yes, it may happen, because memory utility is also part of program, this is independent of the runtime and performance environment of our program. Hope you know, for this we should clear our local variable where ever unneccessary and refreshing the internal table, Also make use of the FREE syntax to avoid such a kind of syntax.
One more case, here our program will run properly both performance wise and Memory allocation wise, but it may creates problem to another programs and transaction like locking and unlocking of data base tables , making utility of text symbols and all can few examples of this kind of issues.
So always do best code,
All the best

Signed Applet - Using same alias while development

Hi,
I am working on Embedded Java Signed Applet. My applet using the TCP/IP thus required to load each time to my Lantronix XPort.
The problem is, every time I change something in the applet, I need to run the following commands again and finally load to Lantronix XPort.
And every time, I required to change the alias name i.e. signapplet17 in the following commands.
Is there any easy way while developing the signed applet
e.g. we can use the same alias name each time i.e. signapplet1 ( I reached to signapplet17)
Or we can avoid the following commands while developing.
jar cmf mainClass.txt DataMain.jar *.class
: Generate key pairs
keytool -genkey -alias signapplet17 -keystore mykeystore -keypass mykeypass -storepass mystorepass
: Sign the JAR file
jarsigner -keystore mykeystore -storepass mystorepass -keypass mykeypass -signedjar SDataMain.jar DataMain.jar signapplet17
: Export the public key certificate
keytool -export -keystore mykeystore -storepass mystorepass -alias signapplet17 -file mycertificate.cer
Thanks.

This is my code that i use to read the graph:
private Graph<Integer, Integer> loadGraph(int year, String type) {
     String graph_dir = ProjectDir.data_dir + "input/Network/vt_kn." + year + "-" + year + "/";
     String graph_name = "vt_kn." + year + "-" + year +".intern." + type;
          Graph<Integer, Integer>graph = new UndirectedSparseMultigraph<Integer, Integer>();
          try{
               GraphMLReader<Graph<Integer, Integer>, Integer, Integer> gmlReader
                    = new GraphMLReader<Graph<Integer, Integer>, Integer, Integer>();
               gmlReader.load(graph_dir + graph_name +".graphml", graph);
          } catch (Exception e) {
               e.printStackTrace();
System.out.println("loaded: " + graph_name);
return graph;
public class ProjectDir {
     public static final String data_dir = "F:/Apache/Tomcat 6.0/webapps/ROOT/app/Data/";
     public static final String script_dir = "../Script/";
     //F:/Apache/Tomcat 6.0/webapps/ROOT/VT/data/
Could you tell me how i could change this code so that i can load from a url instead of a file?

How to establish code standards to make the abap code more readability

Every programmer have their habit to code, but this lead a problem , it is difficult to read other people's code, especially the complex logic.
So how to establish code standards to make the abap code more readability?
I came up with this:
1.Unify the naming rule.
2.Reduce the nest of 'if' statement. (better in less than 4 if statement in one block )
3.Use more Perform to replace the big code block.
Is there any other standards to make our abap code more readability ? （if we establish the standards, in sap is there any tool to help us to follow the rule we set ?）

There are a number of things you could do. Some of which are:
I would recommend creating your own in-house document on Coding standards, some of which you can control with the code inspector.
It is also possible to set up the transport request in such a way that objects that do not pass the SCI test are not allowed to be released.
I would also assign a senior developer to act as quality control for all developments. You can have a rotation scenario where this work can be divided by the number of senior developers you have.

Error while deploying WDJ code

Hi All,
I am getting the following error while deploying WDJ code in NWDS .
1 . The project was not built due to classpath errors (incomplete or involved in cycle).
2 . Missing required library: 'com.sap.security.api.jar'.
I have put the jar file into the project path but still then i am getting these errors . Please help .
Thanks in advance,

Hi,
If u are using simple project then then adding jar into application property would do but if using DC then u must follow below procedure.
You cant just add any external jar file into a DC project.
There is only one way to add a external jar file is by using external library project.
1.create an external library project type DC.
2. put your external jar file into its lib folder.
3. create its public part of type SDA( Assembly if using CE)...and API( Compilation if using CE).
4. just use SDA public part into your webdynpro project as used DC.
5. and when you deploy your webdynpro project on server, this file will also get deployed... remember to use SDA public part..

Error while copying company code

Hi
While copying company code from 0001, following error is giving. Can you please tell me how to go ahead with that:
Message no. TK455
Diagnosis
The value "12 " was entered in the field "REICHWEITE".
This is not possible because it is a numeric field where only numbers may be entered.
The length of the field is 000003.
System Response
The entry was not accepted.
Procedure
Enter only numeric values in this field
Regards,
Priya

Hi,
Did you check the note?
it indicates:
>Use Transaction SE16 to delete all entries in the TNIW5 table that have the two-digit contents '12' in the 'Range of coverage' field.
>If you want to use the lowest value determination by range of coverage (Transaction MRN1) with valuation level = company code, you can maintain your own customer-specific Customizing entries in Transaction OMW5.

Error while creating company code

hi,all,
While copying company code from standard one I am facing this problem
ENTER NUMERIC VALUE ONLY CANCELLED COPYING
Diagnosis message:
the value "12" was entered in the field "REICHWEITE" this is not possible because it is a numeric field
where only numbers may be entered.The lenth of the field is 000003.
Whait does it mean. How to rectify this problem.
pls. help me

Hello Svinir,
The problem is caused by old entries from previous SAP releases which contain invalid data.
The TNIW5 Customizing table is a table with delivery class = C (= Maintenance only by customers - No SAP import). SAP has delivered entries in the TNIW5 table from earlier releases in the incorrect format (entries with the field contents '12') for the TNIW5-REICHWEITE field.
The solution to this
Use Transaction SE16 to delete all entries in the TNIW5 table that have the two-digit contents '12' in the 'Range of coverage' field. If you want to use the lowest value determination by range of coverage (Transaction MRN1) with valuation level = company code, you can maintain your own customer-specific Customizing entries in Transaction OMW5.
For more information use SAP Note 547875
https://websmp130.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=547875
I hope this will solve your your problem

What are the naming conventions we should follow while creating an object

hi
what are the naming conventions we should follow while creating an object in ABAP dictionary, i.e while creating zee table.

Hi,
Namespaces and Naming Conventions
SAP has reserved name ranges for customer objects and SAP objects. Use these customer name ranges to make sure that your objects are not overwritten by SAP objects during the import of corrections or an upgrade.
This documentation lists the customer name ranges for the different system objects.
Only use the customer name ranges. If you do not keep to the name ranges for customer objects you may lose your development objects.
SAP delivers a few system objects with names that fall within the customer name range. These objects already existed when the customer name range was extended from YY/ZZ to Y/Z. These objects are listed in table TDKZ.

What are the steps we have to follow to develop RFC function module

hi
what are the steps we have to follow to develop RFC function module

I will tell you simple example within r/3 systems..
source system - A (SAP R/3 )
Destination System B (SAP R/3).
First create RFC Destination in SM59 - in A System.
Createing RFC Destination - GOTO SM59 Transaction and click R/3 System .
it will go second screen and give ur RFC Name ,IP Address and log on details.
click on test concetion and remote logon.
now create RFC Function module in B System.
goto se37 - create fm with starting with Z* or Y*.
maintain all data like
attribute should be remote enabled
importing is v_matnr
exporting is v_maktx.
write the simple code - select single maktx from makt into v_maktx
where matnr = v_matnr.
Call this fm in report program in se38 in B sytem and copy the FM.
paste this code A System
use ur logic and destination 'RFC Name'.
Reward Points if it is helpful

Error while unpacking program, code 2 Win Server 2008

When trying to run an application (specifically "Image for Windows" by Terabyte Unlimited), I receive the following error message:
"Error while unpacking program, code 2. Please report to author."
I have seen numerous hits for this error while searching Google and nearly all of them point to an issue with a Windows Update. However, it's nearly always for Windows Vista.
I'm getting this error Windows Server 2008.
I have another machine running Windows Server 2008 that does not have this issue.
Is this an issue with a particular Windows Update or could something else be the cause?
