Pass the value of the current case in a case structure to a global variable for use in VIs.

I have built a large queued state machine (>100 cases). In each state, I run a VI that I have created. These VIs are usually not very different from one another. In many cases, I could simply use the same VI over and over again. There is only one problem with that. None of these VIs know which case to send the program to next. I have to change the value of the "NEXT_CASE" constants in the VI and save it under a new name to be inserted into each new case. Now my program consists of hundreds of VIs whose only difference is the value of their "NEXT_CASE" constants. This causes all kind of headaches when I have to insert new cases into the state machine, and it is just too much for me to deal with.
I need to be able to use a global variable to keep track of the current case within my VIs. I could change it from a string to a number and add or subtract from it to determine which case the program should go to next. Since I'm usually only skipping from one case to the next (or the previous) I could use the exact same VI in most cases. Can anyone tell me how to create a global variable that contains the value of the case in my case structure that I could use within my VIs to keep track of the current case? Let me know if you have any questions.

Instead of defining the next state inside the subvi, why not do it in the main vi inside each state case? An output from the subvi could be used with a case structure to determine the next state. Sort of like, if the subvi returns 0 then next state is State3, else if the subvi returns 1 then next state is State4.

Passing Session Values to the Tabular Form Element of a Report Column

Hello,
I'm running application express version 2.0 with a 10.2.0.2.0 database on a 32 bit windows box. I'm trying to figure out sneaky a way to pass the &APP_PAGE_ID., #APP_PAGE_ID# or V('APP_PAGE_ID'); as an element attribute of a Report Tabular Form Element set to display as a Select List (named LOV).
It seems that whatever option I choose, the Element Attributes field will only render the literal value of what I have entered. This is part of the solution but I would like to find a way to pass the current page id.
What I'm trying to do is utilize the ONCHANGE attribute to redirect to a report page in my application when the value from a Select List (named LOV) is selected.
I could work around this by creating my own table output with PL/SQL and HTP.P commands but would really be interested in finding out if I can use the reporting structures which are already available through Application Express.
Any ideas?
Thanks.
Justin.

Thanks for the response Earl. To clarify this is what I've done and what I hope to achieve:
I currently have a LOV for my application that identifies a number of database report types: DB Options, DB Parameters, DB Version, and so on.
I have an application express report being generated for the databases I'm monitoring and it displays as follows:
- HOST -- DBTYPE -------- DBNAME - DBREPORTS
=====================================
- SVR 1 - Oracle 9.2.0.1 - DEV -------- [LOV HERE]
- SVR 2 - Oracle 9.2.0.7 - TST --------- [LOV HERE]
I am displaying the LOV on my report the the options under the reports attribute tab in my application builder. I insert my LOV select list by editing the DBREPORTS column and set the "Display As:" option under Tabular Form Element to "Select List (named LOV)"; I have also added my LOV to the "Named LOV" option under List of Values.
So far this achieves everything I would expect and works quite well (a select list with my report types appears in my monitor report for each DB that is returned).
What I'm interested in doing now is opening a DBREPORT for a given database by simply choosing the report type from my LOV. I can set the "Element Attributes" option under Tabular Form Element to execute a javascript call for any valid event (in my case I'm using ONCHANGE).
My only issue is that I cannot find a way to pass any session values from my page to my Element Attribute. If, in the Element Attributes field I enter:
onchange="alert(this.value);" //my dialogue box will display the value of my current selection when I choose a report type.
What I'd love to be able to do is something like:
onchange="alert('&APP_PAGE_ID.');" //so my current page id is written to the element.
Unfortunately, only my literal text seems to be rendered. Rather than having my dialogue come back with my page number, say 75, I receive the literal value &APP_PAGE_ID.
Notwithstanding any quote issues, I've tried to dump a test html attribute to my source html by entering any of the following in the Element Attributes field:
test=&APP_PAGE_ID.
test=#APP_PAGE_ID#
and as a shot in the dark knowing that I'm not using PL/SQL:
test=V('APP_PAGE_ID');
In every case when I view source I see the literal value of what was entered in the Element Attributes field (ie "test=&APP_PAGE_ID." instead of "test=75").
What makes things a little more frustrating is that I can drop &APP_PAGE_ID. into the Column Heading field (ex My Heading &APP_PAGE_ID.), it renders as I would expect; "My Heading 75". If we could find a solution to this, I could see a number of slick uses for this type of functionality.
Hope this helps,
Thanks.
Justin.

How to get the value of the current form values after "save" in MD form

Hi,
I am trying to run a procedure using the form values right after I save the current records in a master-detail form. When I pass the value using p_session.get_value to the procedure, there is only null value passed. I checked the package body generated and found that the OnReset function runs immediately following the saving of the current records and this onReset function is called within the OnSave procedure. So when I save the current changes, I loose the values in the p_session. Any PL/SQL code I write after OnSave, does not get any p_session value.
Interestingly, in case of just one table form, the OnReset is not within the OnInsert function and it is possible to get the p_session values. OnReset runs after OnInsert and within this two functions we can write any pl/sql code on the Insert button PL/SQL handler.
I have the following questions:
1. Why is the procedure written differently in case of master-detail form ? Why is the OnReset inside the OnSave ? How do we write codes which we want to execute before onReset and after OnSave ?
2. I want to run a procedure after onSave and before OnReset. How do I do that ? Do I have to change the package manually ?
3. If the above is not possible, I can also try to store the values I need to run the procedure before I save in some variable. How do I do that ? It seems I cannot declare variables to store session values inside the pl/sql event code on Save button, because it gives me error. The variable declaration code goes in between the begin and end of genesys.. procedure and that is not allowed in pl/sql
Please help me with this. I definitely need to run a procedure after saving for almost all of my forms. Otherwise I am not sure what to do with my development. I am completely stuck with this. Thanks a lot for helping me out.

To pass parameter values to the object reference of action step in sequence file of teststand programatically using C#.

//Initialize the Engine
            EngineClass myEngine = new EngineClass();
            myEngine.LoadTypePaletteFilesEx(TypeConflictHandlerTypes.ConflictHandler_Prompt, 0);
            Step myStep = myEngine.NewStep(AdapterKeyNames.DotNetAdapterKeyname,StepTypes.StepType_Action);
            myStep.Name = "object";
            DotNetModule dotnetmodule = myStep.Module as DotNetModule;
            dotnetmodule.SetAssembly(DotNetModuleAssemblyLocations.DotNetModule_AssemblyLocation_File,@"C:sequence.dll");
            dotnetmodule.ClassName = "CN";
            dotnetmodule.MemberType = DotNetModuleMemberTypes.DotNetMember_GetProperty;
            dotnetmodule.MemberName = "ISI";
mySequence.Locals.NewSubProperty("object", PropertyValueTypes.PropValType_Reference, false, "", 0);
Sequence mySequence = myEngine.NewSequence();
            mySequence.Locals.NewSubProperty(varName, PropertyValueTypes.PropValType_Reference, false, String.Empty, 0);
mySequence.InsertStep(myStep, 0, StepGroups.StepGroup_Main);
            SequenceFile seqFile = myEngine.NewSequenceFile();
            seqFile.InsertSequence(mySequence);
seqFile.Save("C:\\mySeq.seq");
I have done this,dynamically creating a sequence file in teststand programatically through c#.
Problem is
1.I created an action step and object Reference variable for the step, but i am not able to pass parameter values to the objectReference
2.I am not able to load the sequence in to the main Sequence of the sequence file in the teststand. How can I do these two things.

Hi,

Currently, functionality for retrieving the Metadata Token for a class constructor or member is not fully provided in the TestStand .NET Adapter API. The DotNetModule.GetConstructorMetadataToken() and DotNetModule.GetMetadataToken() methods only return the correct Metadata Token when the member/constructor prototypes have already been loaded. Thus, in the case of your code, when you call DotNetModule.GetMetadataToken(), the method is returning -1 because the member prototype for the Step you are referring to has not yet been loaded.
That means have to do a workaround for your stuff.

Job scheduling(passing the values to the child program)

when i'm trying to schedule a background job(using job_open job_submit and job_close) i'm passing the values of the selection screen(parent program) to my child program using set parameter id. And trying to get the values using get parameter id in the cild program.
But the values of the parent program are not being passed to the child program what may be the cause for it?

rathan,
Why con't you use
SUBMIT... [VIA SELECTION-SCREEN]
[USING SELECTION-SET <var>]
[WITH <sel> <criterion>]
[WITH FREE SELECTIONS <freesel>]
[WITH SELECTION-TABLE <rspar>].
When you start an executable program, the standard selection screen normally appears, containing the selection criteria and parameters of both the logical database connected to the program and of the program itself (see Direct Execution - Reports). When you start an executable program using SUBMIT, there are various additions that you can use to fill the input fields on the selection screen:
SUBMIT... [VIA SELECTION-SCREEN]
[USING SELECTION-SET <var>]
[WITH <sel> <criterion>]
[WITH FREE SELECTIONS <freesel>]
[WITH SELECTION-TABLE <rspar>].
These options have the following effects:
VIA SELECTION-SCREEN
The selection screen of the called executable program (report) appears. If you transfer values to the program using one or more of the other options, the corresponding input fields in the selections screen are filled. The user can change these values. By default, the system does not display a selection screen after SUBMIT.
USING SELECTION-SET <var>
This option tells the system to start the called program with the variant <var>.
WITH <sel> <criterion>
Use this option to fill individual elements <sel> of the selection screen (selection tables and parameters). Use one of the elements <criterion>:
<op> <f> [SIGN <s>], for single value selection
If <sel> is a selection criterion, use <op> to fill the OPTION field, <f> to fill the LOW field, and <s> to fill the SIGN field of the selection table <sel> in the called program.
If <sel> is a parameter, you can use any operator for <op>. The parameter <sel> is always filled with <f>.
[NOT] BETWEEN <f1> AND <f2> [SIGN <s>], for interval selection
<f1> is transferred into the LOW field, <f2> into the HIGH field, and <s> into the SIGN field of the selection table <sel> in the called program. If you omit the NOT option, the system places the value BT into the OPTION field; if you use NOT, the system fills OPTION with NB.
IN <seltab>, transferring a selection table
This addition fills the selection table <sel> in the called program with the values of the table <seltab> in the calling program. Table <seltab> must have the structure of a selection table. Use the RANGES statement to create selection tables.
WITH FREE SELECTION <freesel>, user dialog for dynamic selections
To use this option, the called program must be connected to a logical database that supports dynamic selections. In the calling program, use the function modules FREE_SELECTIONS_INIT and FREE_SELECTIONS_DIALOG. They allow the user to enter dynamic selections on a selection screen. One export parameter of these function modules has structure RSDS_TEXPR from the RSDS type group. Transfer the values of this export parameter by means of the internal table <freesel> of the same structure to the called report.
WITH SELECTION-TABLE <rspar>, dynamic transfer of values
You need an internal table <rspar> with the Dictionary structure RSPARAMS. The table then consists of the following six fields:
SELNAME (type C, length 8) for the name of the selection criterion or parameter
KIND (type C, length 1) for the selection type (S for selection criterion, P for parameter)
SIGN, OPTION, LOW, HIGH as in a normal selection table, except that LOW and HIGH both have type C and length 45.
This table can be filled dynamically in the calling program with all of the required values for the selection screen of the called program. If the name of a selection criterion appears more than once, the system creates a multiple-line selection table for that criterion in the called program. If the name of a parameter appears more than once, the system uses the last value. Note that LOW and HIGH have type C, so that the system executes type conversions to the criteria of the called program. This is important for date fields, for example. Before your program is used in a live context, you should check it using the VIA SELECTION-SCREEN addition.
Except for WITH SELECTION-TABLE, you can use any of the above options several times and in any combination within a SUBMIT statement. In particular, you can use the WITH <sel> option several times for one single criterion <sel>. In the called program, the system appends the corresponding lines to the selection tables used. For parameters, it uses the last value specified. The only combination possible for the WITH SELECTION-TABLE option is USING SELECTION-SET.
If the input fields on the selection screen are linked to SPA/GPA parameters, you can also use this technique to pass values to the selection screen (see Passing Data Between Programs).
The following executable program (report) creates a selection screen containing the parameter PARAMET and the selection criterion SELECTO:
REPORT demo_program_submit_rep1.
DATA number TYPE i.
PARAMETERS      paramet(14) TYPE c.
SELECT-OPTIONS selecto FOR number.
The program DEMO_PROGRAM_SUBMIT_REP1 is called by the following program using various parameters:
REPORT demo_program_submit_sel_screen NO STANDARD PAGE HEADING.
DATA: int TYPE i,
      rspar TYPE TABLE OF rsparams,
      wa_rspar LIKE LINE OF rspar.
RANGES seltab FOR int.

WRITE: 'Selection 1',

      seltab-low = 1.   seltab-high   = 5.
      APPEND seltab.
      SUBMIT demo_program_submit_rep1 VIA SELECTION-SCREEN
                      WITH paramet eq 'Selection 1'
                      WITH selecto IN seltab
                      WITH selecto ne 3
                      AND RETURN.
    WHEN 5.
      wa_rspar-selname = 'SELECTO'. wa_rspar-kind = 'S'.

Passing multiple values to the QUERY BDOC parameter?

hi All,
Below is my Query BDOC Anchor Before Query Execute even handler... I'm trying to pass multiple values to the         bq.Z_PartnerFunction query parameter... i.e.
PARTNER_FCT in( '00000012','ZDIVMGR','ZAREADR')
is it possible without creating new Query Bdoc ?
====================================
Private Sub aempchoicewinTCWSearchTAnchor_beforeQueryExecute(ByRef bq As BusinessQuery, ByRef cancel As Boolean)
If Not bq Is Nothing Then
        If sWcDummy = "Yes" Then
                bq.WcDummy = sWcDummy
        End If
        bq.Z_PartnerFunction = "00000012"
        If ctrlZ_Territory.Value <> "" Then
             bq.PRNB_TerrID = "*" & ctrlZ_Territory.Value
        End If
End If
End Sub
================================
Thanks in advance
Hetal

Hi,
it looks that you already enhanced the query BDoc because you have a new query parameter bq.Z_PartnerFunction, right?
To which BDoc parameter is this BQ parameter mapped? And how looks the related where clause?
For a single filter normally a "=" operator is used. Therefore your example with "in" won't work.
If these three partner functions are fixed then you might hardcoded them directly in the where clause (supposed the BDoc is not used somewhere else where you don't want to have this filter).
Or you might add 3 new BDoc parameters, add 3 new where clauses using a disjunction for them (and using an embracing bracket). In this case always all these 3 BQ parameters need to be filled (or all stay empty) to avoid a SQL syntax error.

How can I pass a value to the command prompt?

I was wondering how can I pass a value to the command prompt with Windows and Linux? I'm more interested in Linux's system than Windows though. Is there a way to return info from the command prompt?

Here is a snippet from http://mindprod.com/jglossexec.html that explains how in detail.
Runtime.getRuntime().exec("myprog.exe") will spawn an external process that runs in parallel with the Java execution. In Windows 95/98/ME/NT/2000/XP, you must use an explicit *.exe or *.com extension on the parameter. It is also best to fully qualify those names so that the system executable search path is irrelevant, and so you don't pick up some stray program off the path with the same name.
To run a *.BAT, *.CMD, *.html *.BTM or URL you must invoke the command processor with these as a parameter. These extensions are not first class executables in Windows. They are input data for the command processor. You must also invoke the command processor when you want to use the < > | piping options, Here's how, presuming you are not interested in looking at the output:
Runtime.getRuntime( ).exec ("command.com /E:1900 /C MyBat.bat" );
Runtime.getRuntime( ).exec ("cmd.exe /E:1900 /C MyCmd.cmd" );
Runtime.getRuntime( ).exec ("C:\\4DOS601\\4DOS.COM /E:1900 /C MyBtm.btm" );
Runtime.getRuntime( ).exec ("D:\\4NT301\\4NT.EXE /E:1900 /C MyBtm.btm" );
There are also overloaded forms of exec(),
Runtime.getRuntime( ).exec ("command.com /E:1900 /C MyBat.bat", null);
Runtime.getRuntime( ).exec ("command.com /E:1900 /C MyBat.bat", null, "C:\\SomeDirectory");
The second argument can be a String [], and can be used to set environment variables. In the second case, "C:\\SomeDirectory" specifies a directory for the process to start in. If, for instance, your process saves files to disk, then this form allows you to specify which directory they will be saved in.
Windows and NT will let you feed a URL string to the command processor and it will find a browser, launch the browser, and render the page, e.g.
Runtime.getRuntime( ).exec ("command.com http://mindprod.com/projects.html" );
Another lower level approach that does not require extension associations to be quite as well set up is:
Runtime.getRuntime( ).exec ("rundll32 url.dll,FileProtocolHandler http://mindprod.com/projects.html" );
Note that a URL is not the same thing as a file name. You can point your browser at a local file with something like this: file://localhost/E:/mindprod/jgloss.html or file:///E|/mindprod/jgloss.html.
Composing just the right platform-specific command to launch browser and feed it a URL to display can be frustrating. You can use the BrowserLauncher package to do that for you.
Note that
rundll32.exe url.dll,FileProtocolHandler file:///E|/mindprod/jgloss.html
won't work on the command line because | is reserved as the piping operator, though it will work as an exec parameter passed directly to the rundll32.exe executable.
With explicit extensions and appropriately set up associations in Windows 95/98/ME/NT/2000/XP you can often bypass the command processor and invoke the file directly, even *.bat.
Similarly, for Unix/Linux you must spawn the program that can process the script, e.g. bash. However, you can run scripts directly with exec if you do two things:
Start the script with #!bash or whatever the interpreter's name is.
Mark the script file itself with the executable attribute.
Alternatively start the script interpreter, e.g.
Runtime.getRuntime( ).exec (new String[]{"/bin/sh", "-c", "echo $SHELL"}";

Compare the value of the current and the Last keyframe

Hey there,
in our company we built some ad, which is an html5 game (view the attachement). The user is able to move the ball through the labyrinth by tilting/moving the phone using the gyroscope-sensor inside of it.
Now our ceo asked me if i would be able to make a video out of it for a power-point presentation.
With a software tool i made a video-screenshot of the iphone screen, with it's interaction.
After that i imported the video to afx and added the video the iphone-frame and the hand.
Tracking of the ball didn't worked because of the rotating texture of the ball, but i followed the movement with a null-object.
Owning the information of the Balls movement in a null-object i connected the hand and the phone to the null-object. Getting the look the hand interacts with the game.
The movement of the Hand was to much so i divided the movement of the distance by 2 in an expression.
NOW THE PROBLEM:
The movement of the ball is just changing the parameter of the "position" not of the "rotation".
So i would like to the value of the current keyframe and of the last keyframe and get a value which is the difference of them (x-y=new value). But i don't know how to collect the data of these by an expression.
Could someone help?

Hey Wow, you guys are really quick here.
Sorry didn't want to confuse anyone here.
I will go a little more into it.
If i am only taking the x value of the position and compare the actual state of x value with the satus of the x value of the keyframe before.
i will take this two values x1 and x2 to take the difference between them. With this new value.
i can modify the angle of the rotation between -90 and +90.
Know what i mean?
but i am not sure if valueattime works in this case because i need the information dynamic.

How to pass a value from the report to a form ( BIT OF URGENT ).

Hi,
I had created a "Form on a Table with Report" on the report I had remove the edit link and set one of the column feilds that functionality. Now I want to know how to pass that value that is clicked ( having hyper link ) on to the form where it runs a SQL query and then displays the reuslts on the form.
Illustrating with an example.
I am having these following columns on the report ( these are the results for the join statement )
JOBNUM JOBNAME DEPTNUMBER SAL EMPNO LNAME FNAME
In the above JOBNUM is having Hyper link as I removed the edit image.
Now this is area I am having problem. When the user clicked on the JOBNUM then on form it should display 20 other columns( pulled from 5 other tables ) which are related to that particualr JOBNUM.
Anybody give me a solution in which area I have to include my SQL statement and how to pass that selected value to that SQL statement.
Cheers,
Krishna

Hi Ron,
I am doing exaclty what you have suggested me but no luck. I started changing the DEMO_CUSTOMERS application to my requirements.The report is working fine and on the report I have created a page attribute to the Hyper linked column and linked that to the page 2 and assign that attribute with #JOBNUM#.
I am able to pass that value on to form when I click on the JOBNUM. But the problem is I am not able to pass that value into the SQL query so that my query pulls 20+ columns on to the Form ( which is second page ).
Small clarification... On the form region it is said FORM NAME and type is HTML is that is the way the APEX was designed or does it need to say region type as FORM.
Thanks for your help in advance.
Cheers,
Krishna.

How to Pass Parameter/Value to the second page????

Hi,
I am trying to display same popup window when I click on ADD,UPDATE and VIEW buttons. I don’t have any problem in displaying the popup when I click on ADD and UPDATE button but with VIEW button I wanted to display the popup at read only mode. In order to do that I have created a bean with session scope and set a ‘SetActionListener‘on VIEW button and set ‘from’ property to true and ‘to’ property to "#{IndividualSummaryDetails.readOnlyAddress}". I could not pass the value of readOnlyAddress to the popup. How can I pass the value of readOnlyAddress to the popup?
This value becomes true when I click on view button. If I pass that value to the popup then I can set the read only property of the fields on the popup with that value. So that the fields become read only.
Here is my View button
<af:commandButton text="#{CoreProperties['Global.commandButton.View']}"
windowHeight="450" windowWidth="600"
useWindow="true"
action="dialog:FromIndividualSummaryDetailsToAddress"
id="justView">
<af:setActionListener from="#{true}"
to="#{IndividualSummaryDetails.readOnlyAddress}"/>
Here is my Bean
public class IndividualSummaryDetails {
private Boolean readOnlyAddress;
public IndividualSummaryDetails() {
readOnlyAddress = true;
public Boolean isReadOnlyAddress() {
return readOnlyAddress;
public void setReadOnlyAddress(Boolean readOnlyAddress) {
this.readOnlyAddress = readOnlyAddress;
This value becomes true when I click on view button. If I pass that value to the popup then I can set the read only property of the fields on the popup with that value. So that the fields become read only.

Passing the values from the graph when we use Navigate to the BI Content

Hi,
The following are the problems which we are facing when navigating to the other BI report.
1)When using the “Navigate to BI content” action the values are not getting passed to the detail report from the graph. Is there any limitation or any alternative to make it work?
When I click on the Bar graph I need to pass the corresponding period and the dimension (EX: Operating Unit – Vision Services R+D) to the detail report.
2)I have tried using the “Navigate to Web page” action. I am able to pass the values but the page is getting opened in another window. I want that page to be opened in the same window so that my presentation variable values are not lost.
3)When I click on the bar graph, I am able to pass the values period and operating unit. But my presentation variable values are lost. I want to retain them.
Please help me out in achieving this scenario.
Thanks,
Chaithanya

Hi,
In the column properties give the navigation to other reports from the interaction tab and make a chart with the column and in the dashboard -->edit dashboard-->in the section where the report is placed--->give 'drill in place'.

Passing null values to the attributes of a CAF operation

Hi,
In CAF I am trying to fetch data through Web Service. For this I need to pass null value for the attributes of the operation.If I set the value to null it gives me missing parameter as the error.
Can anyone tell me how to pass null values to the attributes of a CAF operation?

Hi Xavier,
Declare the two variables of type if_wd_contex_node for e.g. lv_node and if_wd_context_element for e.g. lv_element. Now in the first one lets say lv_node get the refrence of dynamically created node like:
lv_node = wd_context->get_child_node('<node name>').
Then get the refrence of element like:
lv_element = lv_node->get_element( ). (You can also pass index as parameter check the method API)
then just set the value of attribute you want like:
lv_element->set_attribute( exporting name = '<attribute name>' value = '<your value>').

Is there a way to pass different values to the same servlet?
Background:
I have a database that I query to acquire a list of customers, then I show each customer as a link, that when clicked will show details of that customer. (The customer table is dynamic so I can't create a new page for each customer)
When using JSP what I do is
//Do query database
while (rst.next())
String cust = rst.getString ("cust");
out.write("<a href = \"cust2.jsp?cust=" + cust + " \" >" + cust + "</a> ");
}Then on the cust2.jsp. I will use
String str = request.getParameter ("cust");to acquire the customer to get details of.
Is there a way to do the same using servlets?
I could swap to JSP when creating this particular part of the project but it won't look good and it would help me learn a few things when there is another way.

I want to know if there is a way to pass a variable from a webpage link like in my JSP example using servlets.
Here is what I wanted to do:
I have a webpage that contains customer names and each name has a link to the same servlet (let's say the link is famia/servb). I want servb to show detailed information about the customer my visitor clicked in the webpage.
The logic I was thinking is to pass a variable to this servlet, then I can use that variable to know which customer should I query in my database. So that I can show the details to my users.
Here lies my problem, I don't know how I can pass this variable, or even know which customer my visitor clicked. I can't use a new servlet for each client since the customer is in a database and if my customer base grows then I would need to create a lot more web page that does the same thing.
The JSP example I gave is how I will be coding it if I am using JSP, but now I am using servlets. So I was wodnering if there is a way to do this using servlet. Or should I stay with using JSP for this particular logic and just call servb after the JSP page acquired the variable.
I'm trying not to use "<original URL> + ? + <variable> = <value>" (eg: http://www.famia.net/customer?cust=famia) as the means for passing the variable. (or in the example as a means of passing variable cust with value famia)

Filters 'OR' function not passing the values to the sql

Hi,
I am facing an issue with the 'OR' function on the filters that are used in the reports.
The report needs to fetch all the records on the three tables as the user enters the value in the dashboard prompts.
eg: [   update_dt_A1 is prompted
and user_name_A1 is prompted ]
or
[    update_dt_B1 is prompted
and user_name_B1 is prompted ]
or
[    update_dt_C1 is prompted
and user_name_C1 is prompted ]
The values entered in the dashboard prompt gets passed to the filter, but the vaules are not passed over to the SQL that runs on the database, hence the reports shows all values and does not reflect the values entered.
When the 'OR' function is replaced with 'AND' the values get passed to the SQL.
Can anyone help on what is the issue on the filters?
Thanks

Here is how my Filters are set up
Vendor Name is Prompted
AND
Vendor Number is Prompted
AND
[   [Last_update_date_Vendor is prompted
AND
User_name_Vendor is prompted]
OR
[Last_update_date_Site is prompted
    AND
    User_name_Site is prompted]
OR
[Last_update_date_Bank is prompted
    AND
    User_name_Bank is prompted]
The values from the dashboard prompts gets passed to the filter, but the sql that runs does not take the values in the where clause.

Hi Pradeep
Steps:
1. First create an instance for bapi and bind the instance to the bapi node.
Z<bapi name> zb=new Z<bapi name>();
wdContext.nodeZ<bapi name>. bind(zb);
2. Then if u have the import parameter u have to set them by using
    The instance of the above bapi.
    Zb.set<import parameters>;
3. If the bapi has a table parameters then the structure for the table parameters will also be imported
   In the model class.
4. Set the table parameters by creating the instance for that structure and using this instance set it.
   Z<Struct>itm tab=new Z<Struct>();
   Tab.set<table parameters>
5. Then add the structure instance to the bapi instance.
    Zb.add(Tab);
6. Then Execute the bapi after setting the import parameters.
7. If there is any export parameters, then get the values after execution.
Look at this thread for codes

Pass the value of the current case in a case structure to a global variable for use in VIs.
