Rowset parameter that depends on Component value

Hello All,
Suppose you have a list that is filled from the database, and you want to bind a textArea to a rowset that needs the list.getValue() as a parameter.
The list.getValue() is populated during "Process Validation" phase (or "Apply Request Values" if "immediate").
If the rowset is not filled with parameters, "java.sql.SQLException: execute() never called" is thrown during the earliest "Render Resposne" phase.
Even after putting a hardcoded value in the constructor, trying to set and execute the rowset at later stages (after "Process Validation" or "Apply Request Values"), will not update the textArea.
Is there any way to make this?
Followed is the sample page
Many thanks.

Phew, I found the reason, that is textArea is not readonly, so its value is overwritten during "ApplyRequestValues".

How could I pass parameter that depend on values in report from report to form?

In my case, I want to pass 'gno' and 'qno' values of report
to form. When click on the button then the form is showed.
There are automatically values in gno field on form so that user
don't complete this filed.
So I create a button on the report . I enter Javascript in
PL/SQL Code tab in '...after displaying the footer' as follow :
htp.formOpen
(owa_util.get_owa_service_path||'portal30.wwa_app_module.link?
p_arg_names=_moduleid&p_arg_values=1736929105&p_arg_names=_show_h
eader&p_arg_values=YES&p_arg_names=GNO&p_arg_values=1&p_arg_names
=QNO&p_arg_values=2');
htp.formSubmit(null,'New Answer');
htp.formClose;
The above code can pass only static value, while I want to
pass values that depend on value in column of report to form.
So please tell me how can I pass this value to form. I look
forward to hearing from all of you. Please!!!!!!
Thank You

Disabling and or hiding parameter controls depending on the value of a popup

How should I go about doing this? I've set the flags for the popup param to PF_ParamFlag_SUPERVISE like so
def.flags = PF_ParamFlag_SUPERVISE;
PF_ADD_POPUP(
 "Mode",
 6,
 1,
 "Option 1|Option 2|...",
 POPUP_MODE_ID
And I'm capturing the PF_Cmd_USER_CHANGED_PARAM command like so
case PF_Cmd_USER_CHANGED_PARAM:
 ERR(UserChangedParam(in_data, out_data, params, output, reinterpret_cast<PF_UserChangedParamExtra *>(extra));
 break;
static PF_Err UserChangedParam(
 PF_InData* in_data,
 PF_OutData* out_data,
 PF_ParamDef* params[],
 PF_LayerDef* outputP,
 PF_UserChangedParamExtra* extra)
 PF_Err err = PF_Err_NONE;
 if (extra->param_index == POPUP_MODE_ID)
 if (params[POPUP_MODE_ID]->u.cd.value == 2)
 //Code to enable and show the controls
 else
 //Cose to disable or hide the controls
 return err;
Am I doing everything right so far? What code do I need to put in the "if (params[POPUP_MODE_ID]->u.cd.value == 2)" block to disable a parameter? How different would the code be to hide the parameter completely? Can I hid entire topics like I can hide parameters? I'd have a use for all three things, I just can't figure out how to do them.

I took a look at the Supervisor sample project. I've managed to figure out how to disable controls, which I've done like so:
AEGP_SuiteHandler suites(in_data->pica_basicP);
params[CONTROL_ID]->ui_flags |= PF_PUI_DISABLED;
params[CONTROL_ID]->flags |= PF_ParamFlag_COLLAPSE_TWIRLY;
ERR(suites.ParamUtilsSuite3()->PF_UpdateParamUI(
 in_data->effect_ref,
 CONTROL_ID,
 params[CONTROL_ID]
Enabling should be something this instead:
params[CONTROL_ID]->ui_flags &= ~PF_PUI_DISABLED;
What I can't figure out, still, is how to hide a control. I've tried to set the PF_PUI_INVISIBLE flag but that did not seem to change anything. It looks like the Supervisor plugin is setting the exact same flag to hide controls but it must have something else that I'm missing.

LabVIEW 8.6 propositions on how to build application that acts like reader form specified field dependent on which values been selected

Hello everyone!
I am newbie to LabVIEW with some previous experience programming in different languages.
My goal is to build the application that upon my selection needs to give specific values from previously filled and prepared file.
For example, I have different types of operations (milling, drilling, turning..) and different grades (type) of steels (Uddeholm steel grades: NIMAX, IMPAX...and about 40 of them). For every operation there are different input data (Coated insert, uncoated). Based of those information application should give out cutting speed and feed rate data that are stored in some file. I understand I can do it in Excel spreadsheet or LV spreadsheet, I would prefer LV because of portability to systems without Office installed on them. I also understand that all those issues concerning input data for output results I can easily solve with case scenario.
Main issue is decision between different types of files that I can easily address like 2D matrix to get required data, which and how to do it.
I would like to know what I should acknowledge first before doing any further work?
And does someone have some simply prepared VI on which I can work my way on?
If you are willing to help me with guides I would be happy to answer any of your questions.
Vedran Galeta

Thank you very much for your reply.
This application that I am working on is completely static due to communication. It simply needs to provide entry in table depending on selected inputs in front panel, and of course display it front panel. I know what I need to do, as well as the structure. Only thing that I don't know yet how to do it in LabVIEW.
When I mentioned "LV spreadsheet" I meant on read from file option, you got that right.. The thing is that now I have large amounts (not large in acquisition data point of view, 5 spread sheets, with 45 rows and 15 columns) of data saved in Excell, and my goal would be to get that data in LabVIEW application, for the ease of access. And still leave that xls file as is, due to all connections that he have with smaller xls files. So in compact version of the story I am going to use save as comma separated (or tab, that depends of course) values from Excell with or without extra editing of created file in order to load that file into prepared program structure in LabVIEW. After I manage to do that, of course I will work my way for all other extras that I am gonna put eventually in program structure. So this would be like a backbone, I know it sounds simple. As a matter of fact I would probably be finnished allready in VB but highest demand is to do this in LabVIEW, and I am fully down with that.

Actual cost component values

Hi
We are facing an issue that actual cost component values in our system are not calculating correctly. We consider that there might be difference in our understanding regarding the calculation of actual cost component values.
Therefore I want to understand that how actual cost component values are calculated in SAP Material Ledger. I will appreciate if anyone can elaborate this with example and formula, used for calculation.
Regards

Hi Saad,
Please find below about the actual cost calculation in ML.
In ML single -level and multi-level material settlements are available. Multilevel price determination calculates the periodic unit price for a material. The standard price, the single-level differences cumulated in the period, the differences between planned and actual prices, as well as input material differences (multilevel differences) are all taken into account.
The material price calculated in multilevel price determination can be used for inventory valuation.
The actual price for each material can be updated to the material master for the closed period.
-During price determination, the system carries out the following calculation:
=>Daily Transaction
1) Purchasing XYZ Qty 20 Std : 10, Actual : 11
   Dr) Stock XYZ 200                   CR) GRIR 220

LOV SQL query dependent on column value

Hi Gurus,
I have a tabular form, a column of which I would like to display as a dropdown whose list of values is a SQL query containing a where clause on another column value.
For example, say the tabular form displays questions, and that the answers to the different questions are to be picked in list of values that are different for each question. I have tried the following queries for the dropdown list of values:
1- select value_text, value_text from list_of_values_table where question_id=#QUESTION_ID#
2- select value_text, value_text from list_of_values_table where question_id=:QUESTION_ID
3- select value_text, value_text from list_of_values_table where question_id=&QUESTION_ID.
In the 3 cases, I get an error when I run the application saying that the SQL statement is incorrect.
Any ideas?
Thanks in advance,
Guillauem

Anton,
Yes, I am creating a region based on a sql query. The query is the following:
select q.id quest_id, q.name, q.data_type_id, q.lov_flag, a.id answer_id, a.answer_text, a.org_id
from gwb_questions q left join gwb_answers a on q.id=a.question_id, gwb_answers ans right join gwb_orgs o on ans.org_id=o.id
where q.MODULE_ID=:P2_MODULE_ID and o.id=:P2_ORG_ID
Now, in the 'answer_text' column, I would like to display a dropdown containing values that come from a separate table and that depend on the value of the quest_id column. So in the Column Attributes for 'answer_text', I selected Select List (query based LOV) for the Tabular Form Element, and I entered the query mentioned before in the List of Values section (select value_text, value_text from list_of_values_table lov where lov.question_id= ?).
I am not using any API.
Does that make sense?
Thanks for your help,
Guillaume

Report parameter startdate has a defaultvalue or a valid value that depends on the report parameter startdate forward dependencies are not valid

Hi,
Am trying to develop a report the parameter has an issue, it gives me an error.
There are 2 parameter (1st is Date range like start and end date and 2nd is Loan number)
When ever I select date range the Loan number parameter should go blank. If I input a loan number then date range should go blank.
What should I do. Please help
ERROR --report parameter startdate has a defaultvalue or a valid value that depends on the report parameter startdate forward dependencies are not valid

Hi Kay_MD,
If there are only two parameters, we can use first parameter charge the second one, but the second one cannot charge the first one in turn. Because parameter forward dependencies are not valid. To achieve your requirement, we can create another parameter
to control Date_range and Loan_number parameters. For more details, please see:
Add a parameter named ReportParameter1 with two available values: Date_range and Loan_number.
Use the following expression as the default value in Date_range parameter:
=iif(Parameters!ReportParameter.Value="Date_range",1,"") (1 means a useless value)
Use the following expression as the default value in Loan_number parameter:
=iif(Parameters!ReportParameter.Value="Loan_number",1,"") (1 means a useless value)
Please note that the Date_range and Loan_number parameters should enable Allow blank value (“”), and the blank values should also be contained in available values.
If there are any other questions, please feel free to let me know.
Thanks,
Katherine Xiong

Changing the value of a parameter that has been passed into an SSRS 2008 R2 report

I support 200+ reports that all use stored procedures and have many drill downs with built in URLs.
I want to do the below to avoid creating a brand new parameter that I will have to add to literally hundreds of places.
We have what I'll call Param1 that receives a value from the user. That Param1 is passed to the stored procedure(s) for the report and also embedded in any Action URLs for drill downs to other reports from that report. All works great.
Now I have a need to concatenate a string to whatever value they supplied which provides context for the environment in which they are running. The reason I want to do this instead of creating a new parameter is because I need this in all my reports
and as stated above I would have to make 100s of changes to make that happen. If I can figure out a way to concatenate a value to the existing Param1 value I can greatly reduce the number of changes.
I can't seem to be able to find a way to modify the value on an existing parameter that is passed into the report prior to report execution.
I get an error when I simply try to concatenate something to the parameter in its Default property.
I can't find a way to update a parameter value in the Report Code block. There don't appear to be any methods available on the Parameter Collection to set the value of a parameter.
Any ideas?
Thanks!
Nathan

Create a new parameter. Mark it internal, set it's value by expression to:
=User!UserId+"MyNewValue"
and pass it to the proc?

PO Form with Terms & Conditions that Change Depending on a Value in Another Field

Hi - I have read through the relevant topics in this forum and have attempted several of them without luck. I am currently working on a form in which there is an empty JFMain (I do not want to populate fields on this page since I don't want things in this page my "static" header - logos, title, etc. since the Terms and Conditions pages should not show any of this.) On my page 2, I have subforms for all my fields except my Terms and Conditions. (These fields are controlled by a data file.) On my remaining pages I have 3 sets of Terms and Conditions - all about a page long - hard-coded as text and placed in subforms with a dummy field off page to ensure they print. What I want to do is print the subforms from page 2 and then the applicable terms from page 3, 4, or 5 depending on the value in a field located in one of the subforms on page 2. What I currently get is my subforms and then ALL my terms printing. Any thoughts?
My preamble overrides look like this:
^define group:D_HEADER \field$POSITION\reserve".11",in\subformHEADER.
^define group:G_HEADER @group:D_HEADER.
^define group:dummy!FldNotAvail \groupG_Terms_Private_Commodity
^define group:dummy2!FldNotAvail \groupG_Terms_Private_Services
^define group:dummy3!FldNotAvail \groupG_Terms_Public
^define group:JfEndData!EndData @group:D_end.
I had to place the JFEndData! statement into the Preamble since the last subform with fields called before the Terms subforms has a global field from another subform above it. For whatever reason, it was duplicating this subform after printing the Terms and Conditions.
I tried adding a nested if statement into field that will control when I want each subform to print but it was ignored. I also tried hardcoding a group call into the preamble with the logic as well with no results. If someone has example code they can share, this would be great.

A reply to the "Please can some one help me out......." post by Mr BoJangles on 10/29/2007 gives some information about forcing a subfield to be displayed.
A reply to the "Conditional logic" post by Marco Degl'Innocenti on 8/2/2006 gives information on initiating a subform based on the value of a field in the data stream.
A reply to the logic post by Marco DeglInnocenti on 2/22/07 also gives information on initiating a subform based on the value of a field.
I hope these can be of help. If you can't access them on the forum I can repost them.

Shading part of a JTable Cell dependent upon the value of the cell

Hi
Was hoping some one woudl be able to provide some help with this. I'm trying to create a renderer that will "shade" part of a JTable cell's background depending upon the value in the cell as a percentage (E.g. if the cell contains 0.25 then a quarter of the cell background will be shaded)
What I've got so far is a renderer which will draw a rectangle whose width is the relevant percentage of the cell's width. (i.e. the width of the column) based on something similar I found in the forum but the part I'm struggling with is getting it to draw this rectangle in any cell other than the first cell. I've tried using .getCellRect(...) to get the x and y position of the cell to draw the rectangle but I still can't make it work.
The code for my renderer as it stands is:
import java.awt.Component;
import java.awt.Graphics;
import java.awt.Graphics2D;
import javax.swing.JLabel;
import javax.swing.JTable;
import javax.swing.table.TableCellRenderer;
public class PercentageRepresentationRenderer extends JLabel implements TableCellRenderer{
     double percentageValue;
     double rectWidth;
     double rectHeight;
     JTable table;
     int row;
     int column;
     int x;
     int y;
     public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
          if (value instanceof Number)
               this.table = table;
               this.row = row;
               this.column = column;
               Number numValue = (Number)value;
               percentageValue = numValue.doubleValue();
               rectHeight = table.getRowHeight(row);
               rectWidth = percentageValue * table.getColumnModel().getColumn(column).getWidth();
          return this;
     public void paintComponent(Graphics g) {
        x = table.getCellRect(row, column, false).x;
        y = table.getCellRect(row, column, false).y;
          setOpaque(false);
        Graphics2D g2d = (Graphics2D)g;
        g2d.fillRect(x,y, new Double(rectWidth).intValue(), new Double(rectHeight).intValue());
        super.paintComponent(g);
}and the following code produces a runnable example:
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
public class PercentageTestTable extends JFrame {
     public PercentageTestTable()
          Object[] columnNames = new Object[]{"A","B"};
          Object[][] tableData = new Object[][]{{0.25,0.5},{0.75,1.0}};
          DefaultTableModel testModel = new DefaultTableModel(tableData,columnNames);
          JTable test = new JTable(testModel);
          test.setDefaultRenderer(Object.class, new PercentageRepresentationRenderer());
          JScrollPane scroll = new JScrollPane();

Error Parameter WI_ID contains an invalid value in webdynpro abap

Hi Experts,
i am working with webdynpro abap and using work flow in my component , here i am getting error and the error is
Parameter WI_ID contains an invalid value .
its showing the error in windows parameter : wi_id and the wi_id is type sww_wiid
and the same parameter i am using in application parameter .
can u suggest me how to use this parameter wi_id in window parameter and application parameter and what the type should be for wi_id parameter.and what the value should be for application parameter wi_id.
her i am giving the complete error details.
please give me the requried information if u porvided screen that will be very useful

Hi Nawal Kishor Mittal,
thanks for the reply,
i have given the application parameter wi_id with type string also but in 120 client (development) is working fine. when i test in 130 client( testing) its going to dump.
what should be given to application value i given parameter wi_id and what the value should be there.
waiting for reply.
Thanks & Regards.

Moving only one component value into a register AGAL

Hi
Do any of you know if there is any way in AGAL of moving a component value from one register to the other without touching the other components in the register? I notice that the following line...
mov ft1.a, ft0.a
...will also overwrite the rgb components in ft1 with the rgb components from ft0. At least it does on my machine. In other words, specifying components may reorder (swizzle) the components, but doesn't mask them to preserve the value of other components in the destination register. Probably because each register is 128 bits wide, so it's easier for the GPU to just do the operation on all four components anyway. I'm trying to implement the technique described here:
http://http.developer.nvidia.com/GPUGems/gpugems_ch22.html
Under "22.2.2 Curves". It requires me to process each color component independently.

"You can't have an HTML form element map to an Oracle PL/SQL procedure parameter that is defined as a TYPE definition"
Sorry, but this is just plain wrong. Passing values to associative arrays (TYPE xxx IS TABLE OF xxx INDEXED BY BINARY_INTEGER) has been possible at least since OAS 4.0.8.
The following simple procedure prints the values passed to it from a form with multiple occurrences of in_val
CREATE OR REPLACE PROCEDURE test_prc (in_val IN owa_util.ident_arr ) IS
BEGIN
for i in in_val.first..in_val.last loop
htp.p(in_val(i));
end loop;
END test_prc;
(owa_util is a SYS package)
As to the original question, it is very hard to say what the problem is without more details about the error that occurs after the migration.

What is parameter id and default component in data element? Help!

Hi experts,
In the further characteristics, What is parameter id and default component name in data element? what are they used for?
Example: S_CARR_ID.
Thanks
Gopal

Hi,
Parameter ID :- Is used for assigning value to field.
Suppose u call a transaction in u porgram.
and u want to assign some value to field before executing the transaction.
if the field has parameter id u can assign value to field before calling the transaction.
that is it take the default value from the memmory.
and u set value in the memmory using parameter id.

GET PARAMETER -

Basic form 3
GET PARAMETER ID pid FIELD f.
In some cases, the syntax rules that apply to Unicode programs are different than those for non-Unicode programs. See ABAP Unicode - Other Changes
Effect
First, the value stored under the key pid is transferred from the local SAP memory into the field f. If this key is not available in the local SAP memory, the value stored under the same key pid is transferred from the global user-related SAP memory to the field f.
A parameter ID can have up to 20 characters. You can find an overview of the keys (parameters) used in the SAP system description or the appropriate function in the ABAP Workbench.
The Return Code is set as follows:
SY-SUBRC = 0: A value was read from SAP memory. SY-SUBRC = 4: No value was found in SAP memory under the specified key.
Notes
The global user-related SAP memory is available to each user for the entire duration of a terminal session. For this reason, set values are retained when you leave a program.
You should not use SAP memory for temporary storage because a user's parallel sessions use the same global memory.
Example
Read the program name from SAP memory:
DATA : REPID LIKE SY-REPID.
GET PARAMETER ID 'RID' FIELD REPID.
----
SET PARAMETER -
SET PARAMETER ID pid FIELD f.
In some cases, the syntax rules that apply to Unicode programs are different than those for non-Unicode programs. See ABAP Unicode - Other Changes
Effect
Writes the contents of the field f to the global user-specific SAP memory and the local transaction-specific SAP memory under the ID pid. Any existing values under the same ID are overwritten.
Parameter IDs can be up to 20 characters long. They cannot consist entirely of spaces. The SAP system description contains an overview of parameter IDs. You can also produce a list using the ABAP Workbench.
Notes
The global, user-specific SAP memory is available to a user for the duration of a single terminal session. Values written to it are retained even when the user exits a program.
Do not use SAP memory as a temporary storage area, since parallel sessions belonging to the same user all use the same memory area.
Only store data of the types C, N, D, and T, as well as structures that consist of these types, in the SAP Memory.
You can create new parameter IDs using the ABAP Workbench.
Parameter IDs may have a namespace prefix.
Example
DATA REPID like sy-repid VALUE 'RSPFPAR'.
SET PARAMETER ID 'RID' FIELD REPID.

Binding component value to a property or to an implicit object?

Sorry for that newbie question, but it confuses me...
What is the differnce between binding component value to a property and binding this value to an implicit object? In both cases i can refere to the value inside jsp file by:
#{MyBean.someValue}.
The difference is that in first case I need to declare:
<managed-bean>
<managed-bean-name>MyBean</managed-bean-name>
<managed-property>
<property-name>someValue</property-name>
<value>value</value>
</managed-property>
</managed-bean>In second case I don't need to declare anything.
When should I use first type of binding and when the second one?
What are the restrictions in using implicit binding?
