Custom default value in view row class

How do I set a custom default value in a view row class?
There is no create method to override, and I cannot seem to determine whether it's a new row or existing row in the code.
The IDE wizard says it's possible, I can't find it in the documentation.
Thanks,
John

I actually need to pull the custom value from the current row of another view object.
Client uses a combobox to select a 'Location'. Then in the other view objects, I use that location for all new rows. This way they only select their location once.

ALV Grid default values for new rows added with Add/Insert buttons

Hi!
Help, please, to find a way how to set default values for new rows added with Add/Insert buttons in
ALV Grid.

I have found salution:
ALV Grid u2013 Insert row function
Sometimes we need to assign some default values when we create a new row in a grid using standard ALV Append row button. In our scenario we will see how to assign default values to Airline Code (CARRID), Flight Connection Number (CONNID) and Flight date (FLDATE) when a new row is created. To do that we need to handle DATA_CHANGED event in the program like mentioned below.

Default Values in View

I have a view to count daily number of logs in different tables. If for a particular table there have been no logs than view will return null.
How can I set a null value in view to a default of 0?

Something like this perhaps...

Default value for first row in table after row has rendered

I have a master-detail type page where the first row in the detail table appears with no values when the page first renders. After the user enters some data in the master area, the default value is available. I then use something like this to set the default in one column of the first row:
MyVOImpl vo = (MyVOImpl)am.getMyVO1();
MyRowImpl voRow = (MyRowImpl)vo.first();
voRow.setMyAttribute("some value");
When I do this and run the code in the debugger, I can see that the default value is stored somewhere in the row object. However, the value is not displayed in the screen.
What must I do to get the default value to display after the user has tabbed out of the master data area, and before the user attempts to enter data in the row?

Hi. Thanks again.
Here is more detail of the code:
if (pageContext.isLovEvent())
* Form was submitted because the user selected
* a value from the LOV modal window,
* or because the user tabbed out of the LOV input.
* This code executes when the event is either
* LOV_UPDATE or LOV_VALIDATE
String lovInputSourceId = pageContext.getParameter(SOURCE_PARAM)
// Find out the result values of the LOV.
Hashtable lovResults =
pageContext.getLovResultsFromSession(lovInputSourceId);
// Find out which LOV input triggered the event.
if (lovInputSourceId.equals("myLovItemId"))
String myDefaultVar = null;
if (lovResults != null)
myDefaultVar = "some stuff " + (String)lovResults.get("myResultItemId")
if (myDefaultVar != null && myDefaultVar != "") // yes, this is always true in this case
// now set the default for the first line.
// Added lines will be defaulted by the
// EO.create() method.
MyVOImpl myVo = (MyVOImpl)am.getMyVO1();
MyVORowImpl myVoRow = (MyVORowImpl)myVo.first();
myVoRow.setAttribute("myRowItemId", myDefaultVar); // THIS LINE DOES NOT CAUSE DISPLAY TO CHANGE
The problem, as noted in the code, is that setAtrribute() does not cause the default value to display in the field.
What can cause this, and what can fix it?

IBE_INDIVIDUAL customer default values for iStore walk in user

We have enabled walk-in user IBE_INDIVIDUAL for iStore.No approval required for this type of users and they can start shopping/place order right away after registration. How can we make sure that certain values are defaulted for this PERSON type of customer like order type, payment term, credit limit etc?

How to refresh the grid so that default values come on adding new row.

Hi Experts,
In alv grid while adding new row, i want some 2-3 column values to come by default from already existing row in grid.
i am getting new row in internal table with 2-3 default values and rest columns blank on adding new row in alv grid
but the entire row is coming blank, not able to get the default values in new row
how can i refresh the grid so that default values come on adding new row.
thanks

Hi Surabhi,
Use this in Interactive section even if you are doing simple ALV.
DATA:
lv_ref_grid TYPE REF TO cl_gui_alv_grid.
CLEAR : gv_tcode.
*-- to ensure that only new processed data is displayed
IF lv_ref_grid IS INITIAL.
CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
IMPORTING
e_grid = lv_ref_grid.
ENDIF.
IF NOT lv_ref_grid IS INITIAL.
CALL METHOD lv_ref_grid->check_changed_data.
ENDIF.
THis will solve your problem.

What is the best way to implement default values stored in a DB table?

[JHeadstart 10.1.3 build 78]
[JDeveloper 10.1.3 SU4]
We are struggling on how to best implement default values that are stored in a DB table. What we have is a database table with (CODE_TYPE, TABLE_NAME, COLUMN_NAME, DEFAULT_VALUE) as columns. This way the application administrator can administer default values himself/herself. Now we need to find the best way to set these table supplied default values in new rows. Globally we are aware of two ways:
- override create() method on VO
- probably create a View Object on top of the database table with default values (we are capable of transposing the table and return exactly one row with a column for each default value) and use JHeadstarts item property 'Default Value'.
We prefer the latter, since this is more declarative, however we struggle with the EL expression needed to indicate the default value.
If we have a VO named "DefaultValues" with a SELECT on a view on top of our database table (transposed) returning exactly one row, let us say:
SELECT orglanguage, orgtype, orgstatus [...]
FROM v_default_values
--> returning exactly one row
and we want an EL expression on an item that needs the value from orglanguage. What will the EL expression be? Something like:
#{data.DefaultValuesPageDef.currentrow.orglanguage.inputValue}? We tried several things but they do not work. A static default value works, but every EL expression so far does not. We know that using "data" can be dangerous, but thought JHeadstart takes care of preparing the other Page Definitions, so it might be possible when you use JHeadstart.
Or is overriding the create() method the preferred way? Or do we have to look at a Managed Bean for our default values that we refer to from EL (let us say MyAppDefaultValuesBean) and in that case: how do you associate a Managed Bean with a VO?
Any help would be appreciated. Apart from these default values, things are going rather well in this first J2EE/JHS project for us!
Toine

Steven,
Thanks for the reply. Unfortunately whatever we try, we cannot get it to work. We started looking at the second option (since we do need default values also in table lay-out new rows). We created a DefaultValues ViewObject, added it to the Application Module, added an EL expressiona to the Default Display Value property (replacing your ending ")" with a "}" offcourse ;-)), ran the JAG so that a page definition was generated for DefaultValues and we managed to get it prepared when loading for example the Organisation's jspx page. However no default value appears in a new row (not in Form, not in Table layout).
I then created a quick application on top of the HR schema, added a DefaultValues ViewObject using one calculated attribute (set Salary fixed to 1000), added the EL expression to the Salary Default Display Value property in the Employees Group, made sure the DefaultValuesPageDef is prepared by adding it to the parameter section and I see it getting prepared. I also see a managed Bean is created in the Employees-bean.xml.
In the Embedded OC4J log we see:
16:01:01 DEBUG (JhsPageLifecycle) -executing onCreate
16:01:01 DEBUG (JhsPageLifecycle) -CreateEmployeesDefaultValues bean found, applying default values to new row
2006-08-02 16:01:01.825 WARNING [ADFc] Warning: No Method onCreateEmployees and no actionBinding CreateEmployees found.
Is it this warning we should be worried about? Since no default value is created.

We do not understand what is wrong and why the default values do not get created in the new rows (and it is taking us far too much time). Any chance the EL expression is still wrong? It is a shame that any syntax errors in EL expressions are not visible in some logfile. It looks like when EL expressions are wrong, they are ignored instead of raising an error...

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!

Which view object classes should be used by managed bean in ViewController?

I just like to find out which java implementation classes created for a view object should be referenced in a managed bean on the UI side.
For my view object InfoVO, I can create the following classes:
View Object class: InfoVOImpl
View Row class: InfoVORowImpl
View Row Client Interface: InfoVORow
View Row Client Class: InfoVORowClient
Currently, I use InfoVOImpl and InfoVORowImpl in my managed bean so that I can use the getter methods conveniently to access the attributes with proper data types.
I am not sure when I should use InfoVORow and InfoVORowClient instead of InfoVORowImpl.
What are the context and reasons for using InfoVORow or InfoVORowClient instead of InfoVORowImpl?

Hi,
all of these are wrong. If you want to access a method exposed on a ViewObjectImpl class, the you expose the method as a clientMethod (or clientInterface) in the Java options for the View Object (or Application Module if the method is on AMImpl). You should avoid using implementation classes directly in the managed bean. If you need to access a View Object, use its interface ViewObject. If you need anything more specific than that, expose a method on the client interface after which you can access it through the binding layer.

Static Parameters - Default Values Not Showing On Crystal Server

First, I create a basic report with static parameters. Then I assign default values to the parameters. When I run the report in the Crystal Developer, a window pops up and I see my parameters with the default values assigned. At this point, if I run the report, it runs as expected and uses the default parameter values.
However... if I install this same report on the Crystal Server, select 'Properties' > 'Default Settings' > 'Parameters', I see my parameters but I don't see their default values, yet if I select 'View', then a window pops up and I see my parameters and their default values.
I guess I have the following questions:
1. What's the difference between 'Viewing' and 'Running' a report on the Crystal Server?
2. Why don't I see the parameter default values when I select 'Properties' > 'Default Settings' > 'Parameters' in the Crystal Server?
I see the same behavior whether I use CR Developer XI or 2008. The reports are being run on Crystal Server 2008.

Hi,
There are two modes of saving a report. 1 save your report with data (to do this go in File-- Save Report with Data check this option) 2. Save your report without data (uncheck the above said option)
I think you are saving your report without saving the data with your report. Try to save the report with saved data this will keep your parameter default values.
Viewing is just looking at your report data which was saved along with your report. 'Running' is nothing but you are refreshing your report which will give you current data.
Thanks,
Sastry

Default value of report parameter

hi there,
i want to filter my data with a dynamic report parameter as a combo box. its default value should be "all". If "all" is selected, all of the data should be shown.
It worked using the filter:
row["status"] Equal to (params["NewParameter"].value == "all" ? row["status"] : params["NewParameter"].value )
to make it more dynamic i want to replace "all" by the parameters default value. something like
row["status"] Equal to (params["NewParameter"].value == params["NewParameter"].defaultValue ? row["status"] : params["NewParameter"].value )
does anybody know how to get the default value?

You can use this in script or the expression builder to get the default
value of a parameter:
//1stparameter
reportContext.getDesignHandle().getParameters().get(0).getDe faultValue();

How to add default values when adding custom component to design view?

I have a set of custom components (usually) extending Spark components. But when adding our custom component onto design view, how can I define defult values (in AS3).
For example, s:Button has default label = 'Button' when added to application, or mx:DataGrid has 3 columns predefined, but when using custom components there are no predefined values like this.
I can put this values in constructor, but they are not visible in design time, only runtime.
Any ideas? Thanks
Esmin

yes, I am. By the way I've found the solution. Someone might find this usefull.
In design.xml having
<component name="ExtendedTextInput" namespace="mynamespace" category="beta" displayName="ExtendedTextInput"/>
use this
<component name="ExtendedTextInput" namespace="mynamespace" category="beta" displayName="ExtendedTextInput">
<defaultAttribute name="text" value="ExtendedTextInput"/>
</component>
so when adding this component to design view, it will have text setted to value ('ExtendedTextInput' in this case).

How to maintain default values for custom table fields -- Urgent

Hi all,
I've a requirement wherein i need to create a Z table (with maintainence view) in which i'll have date and time as two of its field which should have current date and current time as default value. Can somebody suggest as how am i to maintain the date and time fields defaulting to current date and current time.
Incase if someone is unable to intrepret what i'm trying to say, please query me, i'll elaborate it further.
Please give in your quick inputs which is highly valuable to me and also will be highly appreciated.
Thanks in advance,
Vaishnavi Varadarajan

We have a following custom table which contains the fields Date on which record was created and Name of the person who created the object. We would like to have these to be filled up with SY-DATUM and SY-UNAME respectively.
Using the events, we can achieve this.
Please refer the following link:
http://abapliveinfo.blogspot.com/2007/12/events-in-table-maintenance-in-sap.html
Also,
Write a form routine in table maintanance generator.
1. SE11 > utilities > table maintenance generator
2. environment > modification > event
define the event and form routine to make use of the tigger. in the form routine define an object for the class and call the relevant method.
Or u can do it as:
Table maintenance generator is basically used to do table operations like (insert, delete, modify...).
if you create table maintenance for your table it will build a module pool program, by using you do the above operations.
below is the procedure to create table maintenance generator.
1) Create one function group.
2) after activating your Ztable, choose 'Utilities'----> 'Table maintenance genrator'.
3) then give the authorization group and function group created abobe in the next screen.
4) Then choose the "create" button in your application tool bar, which will creates the module pool program.
5) then create one Tcode by chosing "Transaction with parameters( parameter transaction)".
6) in transaction field give "SM30", select the check box "Skip initial screen".
7) in the below of that screen you can find the "Default values" frame.
8) there under the "name of screen field" select the "View name' and 'update".
9) in value column against to "view name" give you table name, and against to "Update" put 'X' in capital letters.
save it then you can straight away use this newly created Tcode to maintain your table.
Note:- 1) make the modification while saving the data into your table using this newly generated program to carry out your validation (even though it looks like standard program; no need to enter the access key).
2) if you do any changes to your table and press the activate button automatically the table maintenace generator will be goes off, you need to create this again.

BC4J,Setting a default Value In a View With Data From An Other View

hi
I'm developping A BC4J. I want to set the default value of a field By counting the number of rows in an other view.
So I want to instanciate the view and execute the sql statement and get the result.
Is that the right manner to do it or not.
can someone help me to do that
cheers
ghassen

There's lots of ways to skin this cat depending upon whether you mean "database view" or "view object" when you say "view", and individual requirements.
Given database views v1 and v2 with a common key between them
select v1.x, count(*) from v1,v2 where v1.key = v2.key group by v1.x;
either in the database view or in expert mode for the view object ( I think it'll take group by, but never done it ). ( assumption is that v1.x is a primary key for v1 )...
Try this from sql*Plus first to get a feel for how this works.
The catch with the above is that it is "static"... if you can ADD rows to v2 in your application... they aren't visible in the count until saved and requeried.
Another way ( I think... hopefully Oracle folk will kibitz... )
Create your own attribute on the view object like "TheOtherCount".
In the view object's RowImpl, find the "getTheOtherCount". Find the count of rows in the second view object or entity object or rowSetInfo through the method of your choice. ( If you've already set up a master detail relationship that is active you can just get the rowcount! ). Refer to earlier postings on how to get the rowcount, or to create a dynamic view query to get the count.
The nice thing is that this should reflect your counts even if the second view has added or removed rows... but will probably move like a snail.
Note that if you have a need where you want the row count updated in a frame for v1 whenever v2 is added to or removed from... well... then you need to set up some sort of event listener to do a redisplay of v1's frame, I'd think? Since the attribute you've created in the view object is not based on an entity object attribute, it has no way to know when it has been "updated" via an additional or removed row from the target.
I'm posting the above because no one has responded yet... it may form a place to start from. And maybe someone in the know will go "No, No, No... KKirk... it doesn't work that way at all!" and fill us in on how this can be accomplished!
Good Luck
