Hi Pratap,
I have tried the following code to set default value in OAMessageLovInputBean while loading the page but its not working.
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
String delToLoc = (String)pageContext.getSessionValue("deliverTOLoc");
Number delToLocId = (Number)pageContext.getSessionValue("deliverToLocId");
OAApplicationModule am = pageContext.getApplicationModule(webBean);
OAViewObject poHeadervo =
(OAViewObject)am.findViewObject("PoHeaderMergeVO");
PoHeaderMergeVORowImpl poHeaderVoRow =
(PoHeaderMergeVORowImpl)poHeadervo.getCurrentRow();
if (delToLoc != null && !"".equals(delToLoc)) {
// poHeaderVoRow.setShipToLocation(delToLoc);
OAMessageLovInputBean msb = (OAMessageLovInputBean)webBean.findIndexedChildRecursive("DefaultShipToLocation");
msb.setValue(pageContext,delToLoc );
Please suggest me how to resolve this issue.

How to set a default value in the "Our reference"-field in purchse orders?

Hi!
When creating a purchase order the "Our reference"-field in the Communication-tab is empty. Is it possible to configure this so that the field is filled by default with the name of the person who is creating the PO?

Hi,
There is a button named Personal Settings on ME21N screen. Click on that button --> Click on second tab of Default Values --> Click on More fields --> Select Our reference and maintain the default value. This will always come up at the time of creation of PO.
Hope this serves the purpose.
Thanks...

How to set a default value for a page item

I am working with a facility table that has name and address information. The user can add contact name information on a separate page. Since the address for the facility and contact is usually the same, I want to add a default value for the contact address. The facility page is on 201 and the link to add a new contact row is on page 202. I showed in the default value :P201_street for the contact's address. But, when I run the page, the contact address field shows the :P201_street, not the actual facility address. What am I leaving out? Must be something obvious?!
Thanks very much.
Judy

In the default value, I showed: v('P201_STREET1') with the default value type of: PL/SQL Expression and received the following oracle error ==> Item default is not a PL/SQL expression. Use &ITEM syntax. The v('ITEM') syntax is not valid for item defaults. So I changed it to: &P201_STREET1 and got another oracle error , ERR-9132 error in PLSQL expression for item default code, item=P202_STREET1.
Any more suggestions? Thx.
Judy

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.

How to set a default value in my DropDown using the key ?

Hello All,
Can someone advose how I can achieve the above ? I will like to know how to select a default value for the dropdown by key using the key value instead of description.
The reason why I need to do so instead o fusing description is because my application will populate the dropdown using web services based on the language selection. Hence, if I were to set the default value using description, den other languages will not work anymore.
Any help will be greatly appreciated. Thank you !!

Kwok,
Assuming that:
1. You have a node NodeX, where attribute TargetAttr defined
2. You have a DropDownByKey UI control, its property selectedKey bound to NodeX.TargetAttr attribute
Then:
Place in your code:
wdContext.currentNodeXElement().setTargetAttr("yourKey");
VS
P.S. This topic was raised several times, and forum search works good enough to find an answer

How to set the default value of a LOV that is found in a view criteria

HI,
I need to set the default value of an LOV that is found in a view criteria. I tried to set a groovy expression but unfortunately it wasn't read. i also tried to bind the LOV to a bind variable and set the value of the bind variable in the constructor of my backing bean but unfortunately the default value appeared the second time i entered the screen and not on page load.
Can anyone advise where can i set the default value,
Thanks

if you want some default value in LOV. you go to edit list of value wizard-> UI hint->include no selection Item checkbox -checked.use labeled item first of list- and beside that put the label. but when you try to get value, it will show null.but you can manipulate in ur java , if it default value

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 we can find out the default value of the initialization parameters

Hi All,
How we can find out the default value of the initilization parameters from oracle database.
Thanks
Shiju

Hi,
you can find currently used parameter values v$parameter and v$parameter2.
if default values is different real values then you can see alert.log.
because in alert.log you will see non default values, rests is default.

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.
