Enhancing Access Class Query Function

Hi Experts,
I'm customising The PCUI application COMM_BUPAR. I've gone as far as copying this to a custom view as well as addding enhancement fields on the search search.
Now I'd like to extend the functionality of the QUERY method in the class CL_BSP_BP_ACCMOD to cater for this new field. What's the best way of going about this without modifying the standard class method?
Thanks,
Nhlanhla

Hello,
Redifining method is ABAP OO concept. Final result you will have only one method.
When you create Z class with standard as parent class your Z class will inherit the parents QUERY method but as you want to change the logic of the inherited mehod you use some thing called redefinition.
You will have button on the toolbar of methods tab in se24.
Hope this helps you.

Having trouble accessing class get function

Hi;
I am writing a flash AIR application.
I have a document class attached to a FLA to put elements on the stage, It Then instantiates and puts myClass1 an the stage. MyClass1 puts more elements on the stage, and sets the value of a variable _myValue. MyClass1 also has a public getter function which returns _myValue.
The document class then instantiates MyClass2, which is passed a reference to MyClass1. MyClass2 needs to access _myValue in MyClass1.
The following code structure throws an error. While not the exact code, the code below should show haw it was implemented. I have condensed the code to make it understandable.
If you want to see the whole code I'll try.
DocumentClass.as
package ui {
          import flash.display.Sprite;
          public class DocumentClass extends Sprite {
                    public function DocumentClass() {
                              var myClass1:MyClass1 = new MyClass1();
                              addChild(myClass1);
                              var myClass2:MyClass2 = new MyClass2(myClass1);
                              addChild(myClass2);
MyClass1.as
package ui {
          import flash.display.sprite;
          public class MyClass1 extends Sprite {
                    private var _myValue:int;
                    public function MyClass1() {
                              //some code to add stuff to the stage.............................
                              _myValue = 10;
                    public function get myValue():int {
                              return _myValue;
MyClass2.as
package ui {
          import flash.display.Sprite;
          public class MyClass2 extends Sprite {
                    public function MyClass2(referenceMyClass1:Sprite) {
                              var ref:Sprite = referenceMyClass1;
                              var myValue:int = ref.myValue();
This gives me an error
MyClass2.as, Line 39 1061: Call to a possibly undefined method myValue through a reference with static type flash.display:Sprite.

Thanks for your responce. That was one of the problems.
As it turns out another problem was:
public function MyClass2(referenceMyClass1:Sprite)
should have bee
public function MyClass2(referenceMyClass1:MyClass1)

Calling oracle function from Access passthrough query does not return list

Thanks to the help I received in an earlier post I've created an oracle 10g function that returns a list after executing the sql it contains. It works in oracle, using sql developer.
I need to have the list that it returns show up in MS Access via a passthrough query. It's not working so far. The connection string etc is ok, I'm able to use passthrough queries to run sql strings successfully. But when I try to call the function via the Access passthrough query at first nothing seems to happen (ie no list appears) and if I try to run it again, there is a odbc error 'call in progress. Current operation canceled'. There are only the three records in the table. I'm missing something, can anyone spot it?
The passthrough query looks like this
select * from fn_testvalues from dual
Again that runs in oracle.
To create the testing table and 2 functions see below.
CREATE TABLE t_values (MyValue varchar2(10));
Table created
INSERT INTO t_values (
SELECT 'Merced' c1 FROM dual UNION ALL
SELECT 'Pixie' FROM dual UNION ALL
SELECT '452' FROM dual);
3 rows inserted
CREATE OR REPLACE FUNCTION fn_isnum(p_val VARCHAR2) RETURN NUMBER IS
n_val NUMBER;
BEGIN
n_val := to_number(p_val);
RETURN 1;
EXCEPTION
WHEN OTHERS THEN
RETURN 0;
END;
Function created
testing the table:
SELECT val, fn_isnum(MyValue ) isnum
FROM t_values;
VAL ISNUM
Merced 0
Pixie 0
452 1
Now the function that is called in the passthrough query:
create or replace function fn_testvalues
return sys_refcursor is
rc sys_refcursor;
begin
open rc for
Select t_values.*, fn_isnum(MyValue) IsNum from t_values;
return(rc);
end fn_testvalues;

lecaro wrote:
OK. But obviously there is some oracle object that one can call via an Access pass-through query which returns rows?Just to clarify. You could fetch data in Access from an Oracle function that returns a ref cursor using VBA editor. To use a pass-through query Oracle function should be a table function or pipelined table function:
CREATE OR REPLACE

    AS OBJECT(
              val varchar2(10),
              isnum number
CREATE OR REPLACE

    AS TABLE OF testvalues_obj_type
CREATE OR REPLACE
FUNCTION fn_testvalues
    RETURN testvalues_tbl_type
    PIPELINED
    IS
        CURSOR testvalues_cur
          IS
            SELECT testvalues_obj_type(MyValue,fn_isnum(MyValue)) testvalues_obj
              FROM t_values;
    BEGIN
        FOR v_rec IN testvalues_cur LOOP
          PIPE ROW(v_rec.testvalues_obj);
        END LOOP;
        RETURN;
END;
/To test it in Oracle:
SELECT *
FROM TABLE(fn_testvalues)
VAL             ISNUM
Merced              0
Pixie               0

ABAP class or function for retrieving BEx query properties at runtime

Hello Experts,
I'm working on BADI RSR_OLAP_BADI and for a special calculation I need to know which characteristics are in the drill-down of the BEX query, sol later on I can aggregate some key figures using only these characteristics.
Problem is that structure C_s_DATA in method COMPUTE contains all fields of the query (filters, free chars, chars in the rows, etc) and I need to now which characteristics are currently being showing in the Bex analyzer.
So is there an ABAP class or function module I can use to find out this kind of information at run time?
Any suggestion?
Thank you

Tank you for the feedback,
I tried to use the class you provided, but I'm stuck now in how to get from within my class that implements RSR_OLAP_BADI interface, a handle, reference, o whatever represent my runtime query (not the query at design time) . As the class you provide must be instantiated before I can use
In pseudo code could be something like this
DATA my_query type query_ref.
my_query = get_rt_query().
my_query->get_state()

Implicit enhancement to a standard function module.

Hi everybody.
I used an Implicit Enhancement to a Standard function module Customized_Message, at the starting of function module.
Code:
ENHANCEMENT 1 ZFK01_ENHANCEMENT4. "active version
If sy-tcode = 'FK01' and sy-CPROG = 'SAPMF02K' AND I_MSGNR = '230' AND i_arbgb = 'F2' AND I_DTYPE = 'I'.
EXIT.
ENDIF.
ENDENHANCEMENT.
The above is working fine, to the condition what i had given above code.
But my question is, can i use a implicit enchancement to a Standard function module(Customized_message).

Yes, but you should also be aware that 'F2' is a configurable message class in the IMG. You should attempt to solve your issue in that manner first.

XSLT Enhancement with Java, Tokenize Functionality

I tried the following requirement using EXSLT with no luck. Is there any other alternative to tokenize in XSLT 1.0.
The syntax i have here is
<xsl:for-each select="tokenize($this/Field1,',')">
       <xsl:variable name="f1v" select="."/>
     <xsl:for-each select="tokenize($this/Field2,'\|')">
          <xsl:variable name="f2v" select="."/>
          <xsl:for-each select="tokenize($this/Field3,'\|')">
                    <xsl:variable name="f3v" select="."/>
There are multiple for-each based on tokens
I am leaning towards to Enhancing XSLT with Java Function. As i have less experience with Java, can anybody help me with the code that can be used by XSLT for Tokenize functionality.
I have written something like following. I still have errors to fix. But i am not sure about having resultSet or return at the end, to make sure all the tokens were sent to XSLT.
public class MyStringToken
     public static void main(String [] args)
          String str = "sssd;wwer;ssswwwwdwwwwwwwwwww;wwwwe";
          String delimiter = ";";
          MyStringToken my = new MyStringToken();
          my.getTokens(str,delimiter);
     public void getTokens(String str,String delimiter)
          StringTokenizer st = new StringTokenizer(str,delimiter);
          while(st.hasMoreElements())
               try
                    String delString = new String(st.nextElement().toString());
                    return (delString);
               catch(Exception e)
                    e.printStackTrace();
Any help is appreciated

Hi,
I have been searching about, and I have found the next example that maybe can help you, It's a template to tokenize in XSLT 1.0 from the web [http://stackoverflow.com/questions/1018974/tokenizing-and-sorting-with-xslt-1-0]
<xsl:template name="tokenize">
<xsl:param name="string" />
<xsl:param name="delimiter" select="' '" />
<xsl:choose>
    <xsl:when test="$delimiter and contains($string, $delimiter)">
      <token>
        <xsl:value-of select="substring-before($string, $delimiter)" />
      </token>
      <xsl:text> </xsl:text>
      <xsl:call-template name="tokenize">
        <xsl:with-param name="string"
                        select="substring-after($string, $delimiter)" />
        <xsl:with-param name="delimiter" select="$delimiter" />
      </xsl:call-template>
    </xsl:when>
    <xsl:otherwise>
      <token><xsl:value-of select="$string" /></token>
      <xsl:text> </xsl:text>
    </xsl:otherwise>
</xsl:choose>
</xsl:template>
Also I have found the next example of use tokenize in EXSLT from [http://exslt.org/str/functions/tokenize/index.html] It can be that inI your tests you are not using "str:tokenize", no?
<xsl:template match="a">
   <xsl:apply-templates />
</xsl:template>
<xsl:template match="*">
   <xsl:value-of select="." />
      <xsl:value-of select="str:tokenize(string(.), ' ')" />
   <xsl:value-of select="str:tokenize(string(.), '')" />
   <xsl:for-each select="str:tokenize(string(.), ' ')">
      <xsl:value-of select="." />
   </xsl:for-each>
   <xsl:apply-templates select="*" />
</xsl:template>
I hope that helps you.
Best.

XI--- R/3 scenario: directly access and query a Y-table in R/3

Hi forum,
I need to make a XI--->R/3 scenario, i want to access and query a table in R/3 (a Y transparent table),
i have been suggested to use a Sysnchronous call to BAPI/Function module, but i want to know whether there's a way i can access/query a Y-Table in the R/3 directly without using a function module in it,

hi sudeep,
to access a table in r/3 u can either go for an rfc or a server proxy.
>>whether there's a way i can access/query a Y-Table in the R/3 directly without using a function module in it,
do u mean querying the database directly? u "can" ofcourse do it but <b>shud never</b> access r/3 database directly.

Error in adding attachment to the workitem. load:class Query.class not foun

Hi,
We are using WebGui to access the Business Workplace(SBWP transaction) through Portal. For any work item, when i try to import a file from the local PC, i get a screen with the header -"Enter Some FIle attributes". Text displayed in the screen is "Please wait.

Hi all,
I have encountered same problem in ITS 6.20.
Query.class is packed in ws.jar which is stored at C:\Inetpub\wwwroot\<SID>\sap\its\mimes\webgui\99\applets and C:\Inetpub\wwwroot\<SID>\sap\its\mimes\webgui\2002\applets in ITS server.
I increased the trace level to 3 in the Java console to inevestigate the problem further.
== Java console (Trace level 3 ) ===
network: cache entry not found URL: https://hostname.domain.co.jp:443/sap/its/mimes/webgui/2002/applets/ws.jar、version: null
network: Connect to https://hostname.domain.co.jp:443/sap/its/mimes/webgui/2002/applets/ws.jar (Proxy=DIRECT)

java.net.ConnectException: Connection refused: connect

==========================
Then I found out that when system tried to load class Qery.class the connection to ITS was refused becase the incorrect protocol ( https ) was chosen. In my case, SSL was not setup, therefore protocol must be http.
I activated http by changing the configuration file for WGate in C:\Program Files\SAP\ITS\6.20\config\ ItsRegistryWGATE.xml
After that, I restarted the WGate by accessing to http://hoostname.domain.co.jp:port/scripts/wgate/wgate-restart to activate the configuration.
And also I restarted the AGate by restarting the Windows Service "SAP ITS Manager - <SID>".
Anyway, the html (BHTML) file that displays the message below is stored at C:\Program Files\SAP\ITS\620\templates\system\dm\itsdoc.html

Urgent: how to really seperate business logic class from data access class

Hello,
I've this problem here on my hand and i really need help urgently. so please allow me to thank anyone who replies to this thread =)
Before i go any futhur, let me present a scenario. this will help make my question clearer.
"A user choose to view his account information"
here, i've attempted to do the following. i've tried to seperate my application into 3 layers, the GUI layer, the business logic layer, and the data access layer.
classically, the GUI layer only knows which object it should invoke, for example in the case above, the GUI would instantiate an Account object and prob the displayAcctInfo method of the Account object.
here is how my Account class looks like:
public class Account
private acctNo;
private userid;
private password;
private Customer acctOwner;
the way this class is being modelled is that there is a handle to a customer object.
that being the case, when i want to retrieve back account information, how do i go about retrieveing the information on the customer? should my data access class have knowledge on how the customer is being programmed? ie setName, getName, setAge, getAge all these methods etc? if not, how do i restore the state of the Customer object nested inside?
is there a better way to archieve the solution to my problem above? i would appriciate it for any help rendered =)
Yours sincerely,
Javier

public class AccountThat looks like a business layer object to me.
In a large application the GUI probably shouldn't ever touch business objects. It makes requests to the business layer for specific information. For example you might have a class called CustomerAccountSummary - the data for that might come entirely from the Account object or it might come from Account and Customer.
When the GUI requests information it receives it as a 'primitive' - which is a class that has no behaviour (methods), just data. This keeps the interface between the GUI and business layer simple and makes it easier to maintain.
When using a primitive there are four operations: query, create, update and delete.
For a query the gui sets only the attributes in the primitive that will be specifically queried for (or a specialized primitive can be created for this.) The result of a query is either a single primitive or a collection of primitives. Each primitive will have all the attributes defined.
For a create all of the attributes are set. The gui calls a method and passes the primtive.
For an update, usually all fields are defined although this can vary. The gui calls a method and passes the primitive.
For a delete, only the 'key' fields are set (more can be but they are not used.) The gui calls a method and passes the primitive.
Also keep in mind that a clean seperation is always an idealization. For example verify that duplicate records are not created is a business logic requirement (the database doesn't care.) However, it is much easier and more efficient to handle that rule in the database rather than in the business layer.

How to create a model access class ???

HI,
Can somebody tell me how to create a Model Access Class. In the Application Set, i can find the Model Access folder, but it has a list of application sets which is already created and the system asks to select a Application set. I need to create a new application set. Please help.
Regards,
Shiny

Hi Shiny,
I would suggest you not to create a new application set.
If you are enhancing a standard PCUI application, i would suggest you to create new model access classes and assign them to the same application set which is assigned with the standard model access class for that application.
Creating a model access class can be done through the transaction SE24(like any other Z-class).
Go to transaction CRMC_BLUEPRINT_C and you could assign this newly created Model access class to the standard application set. This can be done under Application Element->Application Set->MOdel Access Class.
If you still feel the need to create a new application set altogether, it can be done from Trx CRMC_BLUEPRINT_C->Layout of PCUI-> Application Element->Application set.
I hope it helps.
Cheers,
Gyan.

How do I access classes and methods defined in a wsdl file

I have been provided a wsdl file I need to find out how do I access classes and methods defined in a wsdl file directly instead of doing a wsdl2java...

Several comments :
1- is there any reason to have blank chars inserted after the path ? Seems that you already have a problem there. If possible, try to solve the problem at the source
2- the end of line char is usually CR (Carriage Return, aka ASCII char 13 = $0D = Control-D). But LF (Line Feed = 10 = $0A = control-A) is also used (platform dependent). In LV, you can use the "Concatenate strings" function to add/insert control chars (found in the String Control Palette). However, this will not solve your problem of unwanted added blank chars at the end of your string.
3- you can use the Trim white space.vi (in the "Additionnal string functions" sub-palette) to remove ALL the spaces in your string
4- you can build your own "end space remover" function. :
reverse the string, wire to a "Match pattern" function, use " +" (space + "+") to search for any number of spaces, reverse again the "after substring".
5- there is no point 5 :-)
You may find interesting description of ASCII chars here

How to create a profile to control the access to Query Designer 2004s

Hi all,
I saw the note Note 962530 - NW04s: How to restrict access to Query
Designer 2004s , where in alternative solution there is the approach on
how to create a database table and modify the function module to control the access.
However, we need to a security profile check that can prevent or allow
who can access 04s tools. Because this is easy to maintain and we don't need to modify the database table time to time.
Please update if it is feasible to have a check within the profile
of the users to acces 04s query desinger. This way we can control
effectively who can access new tools.
Thanks,
Dicky

I can suggest that as this is a Security you might wanna ask the Person who is handling Security in your office.
He can add different Roles which can then control their acess.
For e.g. if you want that your user should be able to run Specific Queries a,b,c,d created by you.
I will suggest interact with SEcurity Personal and ask him to create a Role X.
You can then publish your queries in Role X.
So your users will have acess and security for X and they will then run the queries from them.
Likewise, different other options are also there.
If your queries are on Planning cube then things like giving them acess to Tools should take place similarly in different fashion.
Your user can also use Query desinger and can opne queries from Roles .
Hope this helps.

I have just sought to update my lightroom and am now unable to access the develop function and get a note stating that I have reduced functionality what it this about and how do I get my product back

Hi there
I have version 5.7 and every time I opened it I was told that updates are available and to click on the icon to access these. Instead it just took me to the
adobe page with nowhere visible to update. I then sought to download lightroom cc and this is when I could not access the 'develop' section due to reduced
functionality It was apparent that my photos had been put in cc but no way to access them unless I wanted to subscribe.
I have since remedied the problem as my original lightroom 5.7 icon is still available on the desktop and have gone back to that. I do feel that this is a bit
of a rip off and an unnecessary waste of my time though.
Thank you for your prompt reply by the way.

Open "Java Preferences" either from spotlight or your utilities folder...it's probably going to say you need to install a java runtime. Then just click install!
