How to set a column value in a tabular form via button

Hi All,
I am using Apex 3.0.1. And to create the form I am using the APEX interface tool
I have tabular updateable report. In the same page I have a LOV field where I can choose some possible results.
I want to have a button so I can select a value in the LOV, take this value and populate the column value to the LOV value for all rows in the tabular form.
The LOV and the buttons are done.. to update the column I tried creating a pl/sql that is executed when the button is pressed and has the following update in a loop for each element:
begin
for i in 1..APEX_APPLICATION.g_f01.count loop
APEX_APPLICATION.G_F02(i) := :P1_MY_LOV_VALUE;
end loop;
commit;
end;
When I press the button, the page refreshes but nothing happens. I don't see any changes in the Values for the column I am trying to update
Thanks

Hi user477501,
If you are doing this after a SUBMIT, then try updating your data table instead of the g_f02 array. When you page is re-rendered, it should re-query your data table.
If you do not want to submit the page, then try your hand at JavaScript.
A good reference for this is Mike Hichwa's article at:
http://www.oracle.com/technology/oramag/oracle/06-nov/o66browser.html
Be sure to download the example application, it is very helpful.
I hope this helps.

Issue with setting a default value to a Tabular Form field

Hi -
I'm running into an issue setting the default value of a tabular form column. I'm trying to set the default value to the row number (#rownum#). This used to work in previous versions, but now it's returning 0. Is there a was to set this value in the default value attribute of the field with a substitution string?
Thank you in advance for help!

Setting a Default Value within a Tabular Form

Hi All,
Using Apex 2.2.1
Hoping someone can assist. I have the following two scenarios where I would like to set a default value to a column within a tabular form.
Scenario One:
Prior to actually displaying the tabular form on the page, I have a region on this page where I ask the user to select a Application No. first (using a Select List with Submit). Once this item, say P50_APP is set to a value, the Tabular Form region is then presented to the user by where I then allow them to enter certain information required using the 'Add Row' button. One of the columns within this tabular form also represents the Application No.
My questions are:
a) I have made the Application No. within the tabular form as a LOV, so when the user hits the 'Add Row' button, how can I set the initial value to P50_APP value using the 'Default Type and Default' items within the column?
b) Since I am trying to achieve a master-detail type scenario here, if (a) above is not possible, if I hide the Application No. column within the tabular form, how can I set it to P50_APP when the user presses either the 'Add Row' or 'Submit' buttons?
Scenario Two:
Is it possible to pass a value from a tabular form, i.e a column within this tabular form on one page, to another tabular form column on a another page (when the user presses the 'Add Row' button) within the same application?
For example, on page 50 I have the column #APP_NUMBER# passed onto page 60 which is another tabular form that also holds the same column name #APP_NUMBER# , so when the user on page 60 hits the 'Add Row' button, I would like the App Number column default to the one just passed over from page 50.
Is this possible?
Apologies if I am asking the same things in both scenarios - just want to make sure I understand MRUs.
Thanks.
Tony.

Hi Andy,
Thanks for getting back to me but I think you are referencing these default values in the wrong section.
What I am actually trying to set is the value of a column within a tabular form to P50_APP and it seems to me that the only available options for setting default values on a tabular form column are by using:
Default Type: which can be one of:
No Default
Item (application or page item name) or
PL/SQL Expression or Function
and then actual source is set against:
Default:
Unsure as to how to actually set the value of P50_APP which is in session to the individual tabular column mentioned above.
FYI, I have tried selecting for Default Type: Item (application or page item name) and then specifying for Default:&P50_APP. as well as Default Type:PL/SQL Expression or Function and specifying for Default: :P50_APP but to no avail.
Tony.

Column value substitution in tabular form element attributes

We started to discuss this at Re: Tabular form with Ajax
I also mentioned this at Re: how to make only some rows editable in html db.
but thought that this deserves its own thread.
In Doug's sample Sudoku application in that thread, he uses #COLUMN# substitution in the Form Element Attributes and it works fine, but in my example page at http://htmldb.oracle.com/pls/otn/f?p=24317:219 I used the same technique and no matter what I do, the #COLUMN# substitution is not expanded by the Apex engine.
This is driving me nuts, any ideas why it works in one application but not in another?
Thanks

Hm, you might be right.
I copied your row template and modified it at http://htmldb.oracle.com/pls/otn/f?p=24317:219
The styling looks terrible, not sure why, the template is simply
<tr>
<td class="t10data">#EMPNO_DISPLAY#</td>
<td class="t10data">#ENAME#</td>
<td class="t10data">#JOB#</td>
<td class="t10data">#MGR#</td>
<td class="t10data">#HIREDATE#</td>
<td class="t10data">#SAL#</td>
<td class="t10data">#COMM#</td>
<td class="t10data">#DEPTNO#</td>
</tr>I had a lot of trouble getting this to work because the wizard generated tabular form appends 2 hidden fields containing the PK and the row-checksum to the last (editable?) field on each row. If the last editable field has #COL# substitution, it expands the substitution and forgets to close the INPUT tag thus causing malformed HTML (I think this is a bug in the rendering engine).
The readonly condition is sal>1000 which now works. The SAL>1000 fields are now readonly.
But now the update process is broken. If I enter a number in the first blank SAL field (empno=3641) and click Submit, I get no errors but the change is not saved. Wonder why.
Hopefully, Scott (Spadafore) will take mercy on our amateurish experiments and give us some definitive answers soon!
Thanks.

Sun IdM: How to set a multi-value field on document.mainform via javascript

The following will set variables.variable1 to variables.variable2 when the "Script Link" component is clicked. I would like to modify
this so that el2 references a multi-valued element (e.g. a list generated by a Select Field)
<Field>
<Display class='Javascript'>
<String>
function myScript() {
el=getElement(document.mainform,"variables.variable1");
el2=getElement(document.mainform,"variables.variable2");
el.value=el2.value;
</String>
</Display>
</Field>
<Field name='Script Link'>
<Display class='Link'>
<Property name='URL'>
<String>javascript:myScript();submitCommand(document.mainform,%20'Recalculate');</String>
</Property>
</Display>
</Field>
My issue is, if variables.variable2 is a list / multivalued, i get errors trying to traverse through the "array".
How can i read and set a list element via the javascript function above? I've tried things like get(), put() , as well
as path expressions like variables.variable2[0] .
any help would be appreciated....
is there an API somewhere i can reference?

The MultiSelect field-type is a little different than the rest of the fields. If you use the applet version, then selecting/deselecting values cannot be captured by referencing the field directly in javascript.
The way to identify the selections is to use the javascript methods includes/MultiSelect.js file (IDM form submission uses the same method):
fixMultiSelectAppletBeforeSubmit( )
fixMultiSelectNonAppletBeforeSubmit( )
.. and then referencing the "<multiselect-field>_selected" form element.
So in your case, the code should look something like this:
function myScript() {
    fixMultiSelectAppletBeforeSubmit(document.mainform,"variables.variable1");
    var el1 = getElement(document.mainform,"variables.variable1_selected");
    // assign the value to variable2..
    el2 = getElement(document.mainform,"variables.variable2");
    el2.value = el1.value;
}Just make sure ":variables.variable2" is not a multi-select field, else the value set here will be reset during form submission.

SRM 4.0- How to set the default values for product type (01) only for SC

The radio button Service should not be visible.
Also for search help (e.g. search for internal products) where a search should only be possible for product type 01 (goods). The system should not display the product type and internally always search for goods only.
How to set the default values for product type (01) only for SC
We needs to use Search help BBPH_PRODUCT which having parameter PRODUCT_TYPE
Here we can set defalut value 01 but it is not correct one since same search help is using several places.
We need to limit the search help results only for SC.
Kindly help out me ASAP.

The easiest way to set defautl values is to edit the batch class.
Goto the characteiristic and go to update values.
In here you probably have something like 0 - 100 as a spec range.
On the next line enter the default value within this range. At the end of the line, click in the box in the column labelled "D". This indicates the defautl value for the characteristic.
If you need to you can do this in the material classification view as well.
Just to be clear, these values will only show up in the batch record. You can not have defautl values in resutls recording screens.

How to set a variable value on the BPC Data Manager

Hello BPC Experts,
I'm creating a BPC10 NW version demo environment for our prospect customer.
I made a data manager to import BW data into BPC model from BW cube.
I need to import just one month data into BPC from the BW cube that has more than one month data.
When I run the data package manually, I can select a member of the time dimension prompt and I can import specific month data I want.
But, in a case where the program (data manager) runs by JOB monthly,
I can't select a member of the time dimension prompt manually.
So I want to know how to set a variable value to the time dimension prompt from a system date etc. automatically.
Are there any way to set a variable value to the time dimension prompt on the data manager automatically from a system date?
Or, do you have any other solution to import just one month data into BPC from the BW cube that has more than one month data by the data manager running on JOB ?
(without selecting a member of the time dimension prompt of the data package manually)
Thanks in advance,
Keisuke

Hi Gersh
Sorry for my late reply and thanks for your helpful information.
I tried the second way of your information and I could configure it.
And I 'll try first way of your information.

How to refer a column value of a single row in conditional column display?

Hello,
does anybody have an idea, how i can refer a column value of a single row in conditional display of a column?
So my idea is, that a report has a column, which value is only displayed, when another column value of this row has a specific value.
I want to solve this problem with condition type: PL/SQL Function Body returning a boolean.
But I do not know how to refer the column value of each single row!
Thank you,
Tim

Here's a solution that, to me, seems easier to implement but, that's, of course, in the eye of the implementer.
Rather than using APEX to generate a link column for you, actually create the link as part of your SQL.
select '<a href="f?p=102:3:491847682940364::::P3_CONTACT_ID:' || CONTACT_ID || "><img src="/i/themes/theme_1/ed-item.gif" alt="Edit"></a>' CONTACT_LINK, ...
etc.
Test this out. You'll see that it works just like making a column a link using the column attributes.
Next, we'll change the SQL to use a DECODE statement to either display the link or nothing depending on what your criteria is. For example, let's assume you only want a link for active contacts.
select Decode( CONTACT_STATUS, 'A', '<a href="f?p=102:3:491847682940364::::P3_CONTACT_ID:' || CONTACT_ID || "><img src="/i/themes/theme_1/ed-item.gif" alt="Edit"></a>', NULL ) CONTACT_LINK, ...
etc.
This will not display the link in any rows in which the CONTACT_STATUS is not active, i.e. "A"

How to set a default value in dropdown list in Wendynpro ABAP? Help!

Hi Experts,
       I have Webdynpro for ABAP application that shows a DropdownwithKey UI element.
1. I am able to populate the dropdown list. But by default the list is not showing any value. Only when I select a value from the list then it shows it.
So how to set the default value to the first value in the list? Any code sample will be really helpfull.
I have written the following code:
method WDDOINIT .
DATA:
    node_category TYPE REF TO if_wd_context_node_info.
node_category = WD_CONTEXT->GET_NODE_INFO( ).
node_category = node_category->GET_CHILD_NODE( 'CATEGORY' ).
data:    LT_VALUESET type WDR_CONTEXT_ATTR_VALUE_LIST,
           L_VALUE type WDR_CONTEXT_ATTR_VALUE.
L_VALUE-VALUE      = 'V1'.
L_VALUE-TEXT    = 'yesterday'.
INSERT L_VALUE into table LT_VALUESET.
L_VALUE-VALUE      = 'V2'.
L_VALUE-TEXT    = 'today'.
INSERT L_VALUE into table LT_VALUESET.
L_VALUE-VALUE      = 'V3'.
L_VALUE-TEXT    = 'tomorrow'.
INSERT L_VALUE into table LT_VALUESET.
node_category->SET_ATTRIBUTE_VALUE_SET(
             NAME = 'CAT_VALUE'
             VALUE_SET = LT_VALUESET ).
endmethod.
Note that: I am using webdynpro for ABAP.
Thanks
Gopal

I am not sure how it works in Web Dynpro for ABAP, but in Web Dynpro for Java to set default drop down value you will have to set the value for particular attribute (which is linked to the dropdown element) in the context
like
wdContext.currentContext<nodeName>Element.set<FieldName>(<defalut value>)
This generally done in Initialization method of the controller.
