How to show value from another Object as Default value from Prompt

Hi,
   I am creating a web Report with the following filter :
Enrollment Date FROM :   01/01/2011 12:00:00 AM (Default 1st day of previous month)
Enrollment Date TO :     01/02/2010 12:00:00 AM    (Default: 1st day of current month)
There are values for Enrollment date from 01/01/ 2004 till today but user want to have a default value as in brackets above.
When I select prompt option for 'Enrollment Date' all the dates (from 01/01/ 2004 till today) are shown as usual. Database is Oracle and I am able to create Objects in Universe that show the default required dates, but not sure how I use them in the prompt. Is there any way or workaround?
Nanda Kishore.

If i Understand Correctly you requirement you want to set a default value for date in prompt but user should have the ability to change these values if the want ?
In order to implement this you can create a Object in Universe with definition
Date Choice - @prompt('Default or Custom Date','A',{'Default','Custom'},mono,constrained)
Then use this along with the date prompt in query filter as follows.
      Set Data choice =Default
        Date1= Default Date
        and
        Date2= Default Date
OR
       Set Date Choice=Custom
        Date1 = Prompt
        and
        Date2= Prompt

How can i access all the objects of one schema from another schema

Dear All,
How can i access all the objects(Tables,Views,Triggers,Procedures,Functions,Packages etc..) and do the modifications of one schema from another schema (Without using synonyms concept).
Thanks in advance,
Mahi

First of all, synonyms only help you easy reference the object. It doesn't have any implication of object privilege.
As long as you have proper privilege on target object. You can access it with or without synonyms.
Assuming you have proper privilege of objects, you can use following command to assume schema owner.
ALTER SESSION SET CURRENT_SCHEMA = Schema_owner

Modifying static variable in 1object dosent effect value in another object

Hi,
I have a simple class that declares a static variable x...
class DeclareStatic
     static int x = 10;
}I have another class that modifies this static variable (x)...
class ModifyStatic
     public static void main(String[] Args)
          DeclareStatic.x = 20;
}The problem I have is when I run the next class to simply print out the static variable x, I get 10 (the originally assigned value), not 20 (the modified value)...
class StaticTest
     public static void main(String[] Args)
          System.out.println(DeclareStatic.x);
}It is my understanding that by definition of being static, there is only 1 copy of this static variable(x), shared amongst all objects. Therefore, when I attempt to modify this value with a direct reference (DeclareStatic.x =20;), why isn't the change refelected in other classes which access the variable?
This also leads to the question how DO I modify a (non final) static variable from an object and have the change reflected in all other objects?
I have spent some time researching this on-line and in my java books to no avail, any help is greatly appreciated as I am studying to sit the SCJP and attention to detail is everything!
Thanks,

Populating a complex table from another object collection in Syclo Agentry applications

Hello Experts,
I have an object which contains a table data as part of a collection property.
Can I use this object to insert the data in another complex table? I am unable to use a separate bapi wrapper to populate the complex table in this case.
As I have seen the existing complex tables in the Work Manager applications, they all get populated at the beginning of the main transmit.
at this instant, I don't have the data in one of my objects based on which I have to populate my complex table.
So, after the object is filled using a BAPI call, I have to fill up this complex table.
Is it possible to populate this table this way?
Any help will be appreciated.
Thanks,
Arihant Kothari

Arihant,
Yes. You can create an Update Complex Table transaction. It works against the Main Object, but then you choose which complex table you want to update on the transaction. Add the properties you want to update and populate them. To populate from your object collection, use "From other object property" for your initial value on a property, then point to the object and property you want to populate from: Whatever Object -> Whatever property. Use a looping sub-action to loop over your object collection and create/update complex table records with your new transaction. Finish the original sub-action with an Apply. Don't apply after each CT record create because that is much slower. Use a single Apply step after your Loop in the main action. If the CT record already exists, it will be updated. If it does not exist, it will be created.

Query a second form from another form by passing value

Hi,
I have two forms. I am trying to query a second form from another form. I have managed to display the query results in the second form by passing value from the first form. I did it according to the details in the Oracle 9ias Portal Technical FAQ html file.
It works fine when there is already a row in the first form. When I insert a new row in the first form and query the second form which has key from the first form, there is no matching rows displayed which is correct but detail action mode is 'NONE' for all detail rows.
According to the FAQ, it says the following:-
"When the called form is started, it executes a query with the supplied condition (in this case, "where deptno=10"). If the query is successful, the matching rows are displayed in Update mode. If no matching rows are found, the form starts in Insert mode."
It does not happen for me. I get NONE mode for no matching rows. Is this a BUG ? I am working on Portal version 3.0.9.8.0.
Is there something wrong in the code I wrote ? I would like to have all the detail mode as Insert.
Here is the following code I wrote on SUCCESSFUL SUBMISSION OF THE FORM.
declare
my_url varchar2(1000);
v_deptno number;
begin
v_deptno := p_session.get_value_as_NUMBER(p_block_name => 'DEFAULT', p_attribute_name => 'A_DEPTNO');
my_url := 'PORTAL30.wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=1268491962&p_arg_names=_show_header&p_arg_values=YES&p_arg_names=deptno&p_arg_values='||LTRIM(TO_CHAR(v_deptno))||'&p_arg_names=_deptno_cond&p_arg_values=%3D';
go(my_url);
end;

Hi,
The behaviour is OK as in the MD form there are two states "Save" and "Query and Save" and when the form is in "Query and Save" mode that means you can use it for both Query aswell as Save which is decided by your "Master action" if that is None it is used for Query , for Insert you will have to select Insert ,this is the Insert Mode behavior.
If you open a new MD form that is also in the "Query and Save" the same behaviour will be there.
Hope this answers your query.

XML FORM - How to save read-only controls with a default value

Hello everybody,
I have a 3 xml forms, each one to create one type of news. I need to use 3 because each of this forms has their own controls. But the control which indicates the type of news (asociated with a KM Predefined Property) must be common in the 3 forms, in order to use it on searches.
The question is, how can I include in this forms a control:
- Visible for the user
- With a default value defined in the control properties (each form has a different value, corresponding with the type of news)
- Read-only mode
- The value showed in the control must be saved in the associated KM Predefined Property when the user clicks the Save button.
Anyone knows how to do this?
What control can I use?
I was thinking of trying with text boxes, but I don't find the way to make them unwritable (Read only mode).
It is posible using labels?
Thanks.
Kind regards

Hello Jose,
I know you responded with a question... I see it in the email, but I don't see it here! Very odd... but in response:
The first thing I do when I open the Edit.xsl file is do a 'find' for the name of the text field that I want to be read-only (in my test case, it's 'location'). Repeat the find until you see something like:
[code][/code]
Below there is where I put the new code. Mine looks like this:
[code]- <xsl:choose>
- <xsl:when test="location='' and ($editmode='create')">
- <xsl:choose>
- <xsl:when test="./xf:ValidationError/@tagname='location'">
- <input name="location" size="30" type="text" class="urEdfiTxtEnbl" id="field_1157467268006">
- <xsl:attribute name="tabindex">
- <xsl:choose>
<xsl:when test="$accessibilitymode='true'">21</xsl:when>
<xsl:otherwise>3792</xsl:otherwise>
</xsl:choose>
</xsl:attribute>
- <xsl:attribute name="value">
<xsl:value-of select="''" />
</xsl:attribute>
- <xsl:attribute name="readonly">true</xsl:attribute>
</input>
</xsl:when>
- <xsl:otherwise>
- <input name="location" size="30" type="text" tabindex="3792" class="urEdfTxtEnbl" id="field_1157467268006">
- <xsl:attribute name="value">
<xsl:value-of select="''" />
</xsl:attribute>
- <xsl:attribute name="readonly">true</xsl:attribute>
</input>
</xsl:otherwise>
</xsl:choose>[/code]
I put the <xsl:attribute name="readonly"> in both places (when test, and when not test). I'm not entirely sure if that's necessary, but that worked for me.
Hope this helps,
Fallon

How to use P_SESSION.GET_VALUE_AS_VARCHAR2 in MDform item default Value

I have a master detail form based on two tables. In the DETAIL_BLOCK section I have an item named 'APPROVAL_STATUS' based on the column of the same name in the underlying table. I have an unassociated textbox named CURR_APPROVSTAT in the detail form for which I would like to set it's default value to the current value of APPROVAL_STATUS when the master detail form is opened in %3D mode via a hyperlink.
I have tried using the p_session.get_value_as_varchar2 in the default value field of the CURR_APPROVSTAT item, but it generates errors on run.
EX:
Item CURR_APPROVSTAT
default value field
p_session.get_value_as_varchar2(
p_block_name => 'DETAIL_BLOCK',
p_attribute_name => 'APPROVAL_STATUS')
Default Value type:
Function returns varchar2
on run, it generates error that p_session must be declared (I get the same error if I use portal.p_session... also).
default value field
select p_session.get_value_as_varchar2(p_block_name => 'DETAIL_BLOCK', p_attribute_name => 'APPROVAL_STATUS')from dual
Default Value type:
SQL returns varchar2
on run, it generates and error that a right parenthesis is missing.
I have also tried using the following in the Additional PL/SQL - before displaying form:
p_session.set_value
(p_block_name => 'DETAIL_BLOCK'
,p_attribute_name => 'CURR_APPROVSTAT'
,p_value => p_session.get_value_as_varchar2(
p_block_name => 'DETAIL_BLOCK',
p_attribute_name => 'APPROVAL_STATUS')
on run, this generates the error identifier 'P_SESSION.GET_VALUE_AS_VARCHAR2' must be declared
My questions are:
1) is it possible to use the p_session.get_value_as_varchar2 in the default value field?
2) If yes, then what if the proper syntax
3) If no, can I set this value when the MD form opens from the additional pl/sql triggers, and if so, what is the syntax?
any assistance you can offer is greatly appreciated.
Sincerely,
ARM

In my detail block I have 10 rows displaying that may or may not have data after querying. To set the default value in the detail block, you have to set the index value of p_session.set_value. Since I don't know how many rows are already populated, I'm setting the default value to all 10 rows. Is there a better approach?
Here's my code example, which I've placed in the additional PL/SQL section before displaying the form...
DECLARE
l_district_id VARCHAR2(7);
BEGIN
l_district_id := p_session.get_value_as_varchar2
(p_block_name => 'MASTER_BLOCK',
p_attribute_name => 'A_DISTRICT_ID');
FOR i in 1 .. 10 LOOP
p_session.set_value
(p_block_name => 'DETAIL_BLOCK',
p_attribute_name => 'A_DISTRICT_ID',
p_value => TO_CHAR(l_district_id), p_index => i);
END LOOP;
END;

How can I set the date today as default value in a parameter?

Hi,
I have in my report a date parameter and I want to set as default value the date today.
How can I do this?
Thanks in advance

If you are using a datatemplate , you can have a beforereport trigger that will have a package call.
In the package spec, define a date variable and also define the function beforereporttrigger that retruns boolean.
In the body, define the beforereporttrigger function with
begin
select sysdate into specvariable from dual
return(true);
end;
You can then use the variable in the datatemplate as :variable.
Hope this helps.

Selection from Another schema by default without schema name qualifier.

Hi
Oracle10g release 2, LinuxOS
i want my schema (User_1) to always select,insert, update, delete the objects from another schema (User_2) without passing full schema qualifier every time whenever i don't pass any schema name explicitly.
i.e. if i pass the following guerry
select * from table_a;
the table of user User_2.table_a (User_2.table_a) will be queried by default instead of table (User_1.table_a)
and the same implementation is also required in Functions , procedures, sequences etc.
Wishes

Three relatively easy options
1) Create private synonyms in User_1's schema for each object in User_2's schema, i.e.
CREATE SYNONYM table_a
FOR user_2.table_a2) Create public synonyms for each object in User_2's schema. This will make it possible for all users to query user_2's objects without specifying the schema name
CREATE PUBLIC SYNONYM table_a
FOR user_2.table_a3) Change the current schema for the session (potentially in a login trigger)
ALTER SESSION SET current_schema = USER_2There are other options that are a bit more complicated like using enterprise users with shared schemas. But most people are perfectly happy with one of these three.

How to hide PNP selection windows and set default values for PNP.

Hi expert,
I am using HR logical database PNP, but I don't want to display selection windoes for running program on PNP, whereas I want to set default value for some selection items in the program. could you please tell me how to get those two targets?
Many Thanks,

Hi
You have mentioned 2 things.
1. Don't want selection windows for running program for PNP - this can be achieved using the HR Report category - You can get more details on HR Report Category on
HR Report Category
2. I want to set default value for some selection items - This you need to achieve in initialization event of your program.
How you can get this can be explained by INITIALIZATION (SAP Library - ABAP Programming (BC-ABA))

How can I use today's date as default value in query string filter web part in SharePoint

I have a query string filter on my web part page. I am trying to figure out how I can set it's default value to Today? I can't find anything online...

Hi,
Per my understanding, you might want to set a default value to the Query String Filter Web Part.
It would not be able to set default value to the Query String Filter Web Part with the OOTB features available.
By default, with a Query String Filter Web Part in the current page, we can filter other web part in the same page by adding parameters and values in the address bar
of browser.
If setting the “Query String Parameter Name” of a Query String Filter Web Part as “t”, then we can filter the corresponding connected web part by inputting such an
URL into the address bar:
http://sharepoint/SitePages/Page1.aspx?t=value1
Suppose you want to filter the list view with a value dynamically when user opens this page, as a workaround, we can generate an URL with the parameters needed when
page loaded, then redirect user to this URL afterwards. This can be achieved using JavaScript.

I don't think so. I tried to find a property or something in that Input Control but there is nothing to set it that way.

How can I change the numeric and enum default values in a Strict Type Def Cluster?

I have a Strict Type Def cluster that contains 10 Numerical controls and a number of enums. I have edited default values of the numerical controls in the Strict Type Def, in customize mode, performed a "Make Current Values Default" and have done a "Apply Changes" and saved.
This cluster is used in various locations throughout the project and have not found a way to make the cluster default values change downstream. The Strict Type Def (STD) Control appears to have the right values on the front panel. But if I place an instance of this on a blank front panel, and run a wire from it in the block diagram with a probe and indicator, I still get the old default values being passed from the STD.
Solved!
Go to Solution.

There Are No Strict Type Definition Constants
"Even though typedefs only update when types change, instances get cosmetic changes from the definition whenever they update. So one trick to "push" changes to typedef instances is to change the data type, apply changes, and then change the data type back. [edit, March 26 - Note that the typedef instances need to be in memory when you use this trick]."
