Use of classes Vs tables

Hi All,
I have e requirement where i need to select data from tables....... It was told to me that i can make use of classes instead of tables...... I am working on Inbound delivery in EWMmodule.......
can any one through some light on this....... how can i make use of classes to get data from sap tables.........
Regards,
Poonam

Hi Faisal,
Just to correct you it's "Methods of Global Persistent Classes".
Not to hide my ignorance in OOPs, but i don't think persistent classes should be used for mundane selects. It's much easier to write, maintain & troubleshoot a select construct than a persistent class
You can go through this discussion on: Why do we need Persistent Classes ?

Help using scanner class to count chars in file

Hi all, I am learning Java right now and ran into a problem. I need to use the Scanner class to accurately count the number of chars in a file including the line feed chars 10&13.
This what I have and it currently reports a 201 byte file as having 194 chars:
     File file = new File(plainFile);
     Scanner inputFile = new Scanner(file);
     numberOfChars = 0;
     String line;
     //count characters in file
     while (inputFile.hasNextLine())
          line = inputFile.nextLine();
          numberOfChars += line.length();
I know there are other ways using BufferedReader, etc but I have to use Scanner class to do this.
Thanks in advance!

Wow guys, thanks for the help! I've got a RTFMWell, what's wrong to have a look at the API docs for the Scanner class?
and directions that go against the specs I said.Is that so strange to suggest a better option? What if I ask a carpenter "how do I build a table with a my stapler?". Should I give the man an attitude if he tells me I'd better use a saw and hammer?
I'm also aware that it "eats" those chars and obviously looking for a way around that.
I've looked through the java docs, but as I said, I'm new to this and they're difficult to understand. The class I am auditing req's that this be done using Scanner, but I don't see why you demand an explanation.
Can anybody give me some constructive help?Get lost?

How to use application class reference in the controller methods of BSP

Hi,
I have created a bsp application and also created an application class and assigned it to the application class. In the application class, I have created attribute TEXT type string(public and instance parameter).
In the controller let's say main.do, I am trying to give a value to to the text by adding the following code.
application->text = 'test'.
I am getting syntax error saying field 'text' is unknown. It is not contained in one of the specified tables nor defined by DATA statement.
Please can someone let me know how to use the application class in the coding with an example. I couldn't find how exactly this has to be reference. Please help.
Best regards
Siva

Hi,
if you are having main controller and sub-controller then you may need to use below coding to use application class reference.
*Data declaration
DATA: obj_cntrl        TYPE REF TO cl_bsp_controller2,
         obj_sub_cntrl   TYPE REF TO z_cl_sub_cntl,
         application TYPE REF TO z_cl_application.
*Get the controller
CALL METHOD obj_main_cntrl->get_controller   "obj_main_cntrl is the object of main controller
    EXPORTING
      controller_id       = 'SUB'   "Controller ID
    RECEIVING
      controller_instance = obj_cntrl .
obj_sub_cntrl ?= obj_cntrl .
application ?= obj_sub_cntrl ->application.
or simply use below code in your controller method.
application ?= me->application.

Hello All,
I am facing a similar problem.
I have checked the following customization "SPRO --> Cross Application component -->Classification system --> Class --> Maintain Object type and class,
Here select the MARA table click on the object and check class type 023 is assigned or not."
Class type 023 is not assigned there. When i try to add a new entry I get the following error message
"Specify the key within the work area".
I referred to the following note :OSS Note 1066606, but that is concerned with AFS component.
Kindly provide me a solution as soon as possible.

How to use global classes and display returned data?

Hello experts,

When I replace itr by OREF I get:

I then try to change it to dref_tab. I get:

Any idea? By the way, must there be a HANDLE event for this to work?

Thank you for your service

I don't know about any TableSorter class, but I suppose you mean javax.swing.table.TableRowSorter.
The TableRowSorter is to be attached to the JTable, not to the data model. Here's a cut'n'paste from the last time I used it:
RowSorter<TableModel> sorter = new TableRowSorter<TableModel>(tableModel);
myTable.setRowSorter(sorter);
And heres from the JDK1.6 documentation:
TableModel myModel = createMyTableModel();
JTable table = new JTable(myModel);
table.setRowSorter(new TableRowSorter(myModel));
Check out http://java.sun.com/javase/6/docs/api/javax/swing/table/TableRowSorter.html. I find it to be good documentation.

Adding custom fields in FPM_FORM_UIBB using feeder class

Hi,
We have requirement to add custom fields in form uibb using feeder class in Health and safety module at incidents report.
Please provide me some usefull documents and reference links.
Thanks
Murali Papana.

Hello Murali,
1. Copy the Feederclass to customer namespace (ZCL_HRESS_PER_DETAIL_XX)
2. Create a new TYPE in you class; e.g. S_CUSTOM_FIELDS
3. Add a type definition
Example:
private section.
*"* private components of class ZCL_HRESS_PER_DETAIL_XX
*"* do not include other source files here!!!
"--- BEGIN - Enter here your type definition
types:
    BEGIN OF S_CUSTOM_FIELDS,
      YOUR_FIELD       TYPE STRING,
    END OF S_CUSTOM_FIELDS .
"--- END - Enter here your type definition

Finally in the above mentioned method, i am able to see the output values of ALV tree list in the internal table of mt_output_table.
But these are SAP Standard Class and method.
My doubt is, How to get these internal table values in my Zprogram.
is there any user exit or badi can we use in the method of class???? Actually my system is 4.6C
Please suggest me on this problem.
Thanks in advance

First your getInstance() method returns 'singleton' which you havent declared/init anywhere.
your getAll() method needs to be static if you need to call it the way you are doing.
In your getAll() method u are passing a parameter called patientRecord ... where have you declared/init it.
i think you have to do something like this ... if i have understood you correctly.
/* THIS IS IN YOUR SERVLET*/
Collections c = database.getAll();
out.println(C);
/* YOUR FlatfileDatabase CLASS HAS SOMETHING LIKE THIS*/
public static FlatfileDatabase getInstance() {
return new FlatfileDatabase();
public static Collections getAll() {

Using Vlookup over several tables

Hi I have read the following link
https://discussions.apple.com/message/16992843#16992843
I am looking to do something similar. I have got five tables for 5 different classes.
Column A has names B-K has results of the kids athletics achievements.
What I would like to do is find the best person across all tables at each event. I'm not sure if I can do a direct vlookup as it will be referencing from different tables.
Is my best option to create a new table which will show the best person for each event from just one table.
So basically i will create a new table per class table once I have found out who is best in that single class create another table that has best of all classes and then lookup that way? Although i'm adding tables it seems an easier way of possibly getting the end result?
Table 1 = Class 1
Table 2 = Class 2
Table 3 = Class 3
New table = best of class,1,2&3
New table = best?

Here's an example of VLOOKUP operating across three tables to find the 'best' 'performance. examples are small, but scaleable. "Best' may be either 'largest' (distance or height events–row 2) or 'smallest' (timed events–row 4). Caveats below.
Formulas differ only in using MAX or MIN to determine the search value:
Bis::B2: =MAX(Class A :: A,Class B :: A,Class C :: A)
Bis::B4: =MIN(Class A :: A,Class B :: A,Class C :: A)
Lookup formulas are the same in both cases:
A2: =IFERROR(VLOOKUP(B,Class A :: A:B,2,FALSE),IFERROR(VLOOKUP(B,Class B :: A:B,2,FALSE),(VLOOKUP(B,Class C :: A:B,2,FALSE))))
A4: =IFERROR(VLOOKUP(B,Class A :: A:B,2,FALSE),IFERROR(VLOOKUP(B,Class B :: A:B,2,FALSE),VLOOKUP(B,Class C :: A:B,2,FALSE)))
Caveat: Like all Lookup formulas, this one will stop at the first occurrence of the value it is looking for. If more than one student has the 'best' score, only one name will be returned. That's not an insurmountable problem. but it is one that won't be solved using only LOOKUP or one of it's variations.

CSS Class for Table Cell Text

When we were using messageStlyedText in a table region, it was shriking multiple whitespaces to a single whitespace. To solve the problem we are planning to use "rawText" with <pre> tag. But we are not able to specify the default CSS class for a table cell text. Can you please let us know the CSS class to use so that even if we use rawText UI(font, size etc) is similar to adjacent messageStlyedText columns ?
Note: We are not using formattedText because it is not allowing to add prompt.

Please try using CSS class OraTableCellText
Thanks

Table JAVA$CLASS$MD5$TABLE is not created by loadjava

When loading a class using loadjava, the table JAVA$CLASS$MD5$TABLE is not created (in the schema where the class is loaded) by the loadjava tool although it should do this according to the doc. Where is this table located?
The class loads successfully and is skipped when loading a second time. The force option is not used.
Version is: Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit

IN order for a registered schema to be available to other users the schema must be registered as a GLOBAL, rather than a LOCAL Schema. This is controlled by the third agument passed to registerSChema, and the default is local. Note that you will also need to explicity grant appropriate permissions on any tables created by the schema registration process to other users who will be loading or reading data from these tables.

Design question about when to use inner classes for models

This is a general design question about when to use inner classes or separate classes when dealing with table models and such. Typically I'd want to have everything related to a table within one classes, but looking at some tutorials that teach how to add a button to a table I'm finding that you have to implement quite a sophisticated tablemodel which, if nothing else, is somewhat unweildy to put as an inner class.
The tutorial I'm following in particular is this one:
http://www.devx.com/getHelpOn/10MinuteSolution/20425
I was just wondering if somebody can give me their personal opinion as to when they would place that abstracttablemodel into a separate class and when they would just have it as an inner class. I guess re-usability is one consideration, but just wanted to get some good design suggestions.

It's funny that you mention that because I was comparing how the example I linked to above creates a usable button in the table and how you implemented it in another thread where you used a ButtonColumn object. I was trying to compare both implementations, but being a newbie at this, they seemed entirely different from each other. The way I understand it with the example above is that it creates a TableRenderer which should be able to render any component object, then it sets the defaultRenderer to the default and JButton.Class' renderer to that custom renderer. I don't totally understand your design in the thread
http://forum.java.sun.com/thread.jspa?forumID=57&threadID=680674
quite yet, but it's implemented in quite a bit different way. Like I was saying the buttonClass that you created seem to be creating an object of which function I don't quite see. It looks more like a method, but I'm still trying to see how you did it, since it obviously worked.
Man adding a button to a table is much more difficult than I imagined.

To Use Cursor or TYPE table Index by PLS_integer

Hi All,
Let's see if I have table with no. of records 19,26,20,000.
If I want to loop through all the records which will be a optimized way To Use Cursor or TYPE table Index by PLS_integer.
Please guide.
Thanks.

What is it you want to do to/with the rows you're looping through?
Ideally you want to avoid looping, as that's row by row (aka slow by slow) processing and it's expensive time-wise.
If you're doing DML (insert/update/delete) then you're best off doing it in one sql statement, rather than looping.
