WD(ABAP) - how to populate items in itemlistbox

Is there any reference about how to populate items in Itemlistbox? I have tried to bind a context node with cardinality 1..n and Selection 0..n to the datasource of a itemlistbox element. The node contains two attributes jy and jy_text representing value and text repectively. I assign some sets of data to the attributes and finally bind the table to the node. But it doesn't display anything in the itemlistbox at runtime. Does anyone have idea?
My code is like this:
=====================
DATA:
    NODE_HEAD                           TYPE REF TO IF_WD_CONTEXT_NODE,
    NODE_JY_LIST                        TYPE REF TO IF_WD_CONTEXT_NODE,
    ELEM_JY_LIST                        TYPE REF TO IF_WD_CONTEXT_ELEMENT,
    STRU_JY_LIST                        TYPE IF_MAIN=>ELEMENT_JY_LIST,
    tb_jy_list                          like table of STRU_JY_LIST,
    tb_is                               type table of v_tb038a_std,
    st_is                               type v_tb038a_std.
* navigate from <CONTEXT> to <HEAD> via lead selection
NODE_HEAD = WD_CONTEXT->GET_CHILD_NODE( NAME = `HEAD` ).
* navigate from <HEAD> to <JY_LIST> via lead selection
NODE_JY_LIST = NODE_HEAD->GET_CHILD_NODE( NAME = `JY_LIST` ).
select ind_sector text into CORRESPONDING FIELDS OF TABLE tb_is from V_TB038A_STD where SPRAS = '1'.
LOOP AT tb_is into st_is.
STRU_JY_LIST-jy = st_is-ind_sector.
STRU_JY_LIST-jy_text = st_is-text.
insert STRU_JY_LIST into TABLE tb_jy_list.
ENDLOOP.
NODE_JY_LIST->bind_table( tb_jy_list ).

Hi Fred,
You should check the following:
The text property of the listbox should bind to the text attribute of your context node.

How to populate item category tree with UNSPSC codes?

I have created an application engine to read a UNSPSC code csv file and execute a component interface to load the item categories. I am having a problem updating the tree we use in ePro. Do I need to set up something before I run this? It looks like you can't add nodes if the category doesn't exist and you can't add categories to the tree if the node doesn't exist. We do not have Catalog Management installed.
Edited by: jbelanger on Aug 4, 2010 8:23 AM

Dear Friend,
I am new to the iProcurement functionality of mapping UNSPSC code to Item Category Flex field Segments.
Please help me how this functionality works.
Does Oracle provide any standard way to map the codes to flex field.
Do we need a customization.
Any useful documentation will be really helpful.
Thanks in advance

How to populate List Item from the table in a form builder

I want to know how to populate the List Item (pop up menu and combo box) from a table.
Supposing I have a table Customer(cust_id,cust_name)
and now I want to populate it in such a manner that I can update the data back to the database and also access the list on the form.

This is the method i am using to populate a list.
1- First of all you need to create a non-database list item for customer_name.
2-create this procedure
PROCEDURE populate_list_with_query
--Populates the given list item with the specified query.
(p_list_item in VARCHAR2
,p_query in VARCHAR2)
IS
/* Name the record group after the list item (no
block prefix). */
cst_rg_name constant VARCHAR2(30) :=
GET_ITEM_PROPERTY(p_list_item,item_name);
v_rg_id RECORDGROUP;
BEGIN
v_rg_id := FIND_GROUP(cst_rg_name);
IF ID_NULL(v_rg_id) THEN
v_rg_id := CREATE_GROUP_FROM_QUERY(cst_rg_name,p_query);
END IF;
IF POPULATE_GROUP(v_rg_id) = 0 THEN
POPULATE_LIST(p_list_item,v_rg_id);
/* Force display of first list element label
in the list item. */
COPY(GET_LIST_ELEMENT_VALUE(p_list_item,1),p_list_item);
END IF;
END populate_list_with_query;
3- Create When-Create-Record on the block level and write this code
BEGIN
POPULATE_LIST_WITH_QUERY('bk1.customer_name',
'SELECT customer_name, to_char(customer_id) FROM customer');
END;
In this example, the customer name is the (visible) list label and the customer ID is the (actual) list value
i hope this will solve your problem ...

How to populate Reference Tab of CG02 in ABAP?

Hi,
I need to know how to populate the RefSpec field under Reference Tab in CG02 from an ABAP program.
I was able to populate the Identifiers tab and the physical/chemical properties using the FM C1E5_SUB_EXPERT_DATA_CHANGE.
Can i populate the Reference tab using the same FM? if yes, which parameter/table should i pass the value.
thanks.

Hello all
as explained it is always better to use the BADIs. The Function modules are internally used (form the SAP perspective). If you perform later SAP updates/upgrades etc. you are on the save side if you use the BADIs and if you try to prepare an OSS you will be supported. If you try to prepare an OSS regarding the function module in most cases you will not be sucessful.
But may be take a look here:
BAPI_BUS1077_CHANGE and BAPI_BUS1077_DELETE for referenced data
and here
BAPI_BUS1077_CHANGE failling for identifier long texts
The use of the BAPIs is still not easy.
With best regards
C.B.

How to programmatically populate items for an InputComboBox?

I'm using JDeveloper 11g Release 1 to build an ADF application. I need a combo box field from which a user may select a predefined option or in which she may type her own entry before submitting. It appears the RichInputComboboxListOfValues component will allow this functionality, but I also need to populate the list items programmatically. From what I have researched thus far, the InputComboboxListOfValues needs to bind to an LOV from the model and can not be populated from the backing bean.
Is this true? If so, can anybody please suggest an alternative that will allow the same functionality?
If not, will you please help with an code sample that demonstrates how to populate the InputCombobox list items from the backing bean? I see that the object includes a .setItems() method, but it is deprecated.

You can base this on a backing bean model.
See: http://jdevadf.oracle.com/adf-richclient-demo/components/inputComboboxListOfValues.jspx

How to populate the field Discount Percent (DIS) in the outbound S1ORDEXC?

Hello all,
I am working with the Spec2000 to send out the IDOC S1ORDEXC.
Does anyone know how to populate the field Discount Percent (DIS)?
This field length of Discount Percent is 2 characters, but our customer discount in the Princing Conditions (Sales Order) is longer than 2 characters (ex: 7.500-%)
Thank you

Hello Thuan
I guess you are working with IS- ADEC and SPEC 2000. I am not an expert on this but leave you some hints from OSS notes I came across.
It appears like Discount Percent - DIS and Procurement Discount Percent -PDP are complementary and mutually exclusive. If one exists, the other need not.
Looks like DIS is computed as (100-PDP)/100 and it is just a 2- integer data (as in 20 Percent). It is a kind of multiplier (Factor), example if PDP discount is 10 percent, then DIS (Factor) is 0.9 and so final (net) price after discount = Price*0.9.
" If the discount comes in the S1BOOKED inbound into SD in the field DIS, then the discount has to be sent back in the DIS field .. if it came in the PDP field then it has to be sent back in the PDP field. If there was no discount in the incoming IDoc, then the discount has to be filled in the PDP if there was a change in the discount".
KDATE in SPEC 2000 file maps to DIS and KPERC to PDP.
PDP has 4 characters and per OSS note 440380, the point is ignored meaning you can work with 1225 instead of 12.25.
So may be you can work with PDP?
OSS notes: Apply to older releases but may still be applicable conceptually speaking.
456153 - S1ORDEXC does not send out Discount
440380 - PDP has only 4 characters in the SPEC IDoc instead of 5
596042 - Discount percent DIS not considered e processing S1ORDEXC
698668 - Incorrect calculation of unit price for PO item by S1ORDEXC
Let me know you final findings.

How to populate a Table inside a structure?

Hello,
Im very new to ABAP and Im having a rather sily problem. I have a Structure (ZSHIPMENT) with one component (CASES) of the type Z_CASE_TABLE. Z_CASE_TABLE is a table with a line type of ZCASE_STR. ZCASE_STR is a Structure with one Component (CASE_ID) of type String.
So ZSHIPMENT - ZCASE_TABLE - ZCASE_STR - CASE ID.
I want to write some code to create this object and use it in a method.
This is what Im trying:
method TEST_02.
DATA: Shipment TYPE ZSHIPMENT,
case TYPE ZCASE_STR.
case-case_id = 'case1'.
INSERT case INTO Shipment-cases.
endmethod.
But I get this error: CASE is not an internal table - the "OCCURS n" specification is missing.
Can someone give me a hint on how to populate my memory object?
Ive tryed all shorts of things but I never get it to work.
Thanks in advance.
Gonso

Ramiro,
wow! you hit the nail in the head! The zshipment type was not active to its latets version. Thanks to the debugger I could see its real face.
Thanks!!!!

How to populate list component via xml file?

There is a TextArea component that should show the name and
the description of the item selected in the list component. But I
dont know how to populate list with external XML and what should be
the coding in flash as well as what should be written in the XML.
Please help.

Here's an xml file listing a couple of brother comedy teams:
<?xml version="1.0" encoding="UTF-8"?>
<team>
<brothers>
<Marx>
<name>Groucho</name>
<name>Chico</name>
<name>Harpo</name>
<name>Zeppo</name>
<name>Gummo</name>
</Marx>
<Howard>
<name>Moe</name>
<name>Curly</name>
<name>Shemp</name>
</Howard>
</brothers>
</team>
Open a new .fla and save it in the same folder as the .xml
file. Place a List Component on the Stage and name it (in this
case, "comicTeams_list"). In the first frame write the following
ActionScript:
//create XML object and load external xml file
var broList:XML = new XML();
broList.ignoreWhite = true;
broList.onLoad = processList; // this is a function that will
be written below
broList.load("populateList.xml");
function processList(success:Boolean):Void{
if(success){
loadList();
}else{
trace("Load failure");
function loadList():Void{
var broName:String;
var listEntries =
broList.firstChild.childNodes[0].childNodes[0].childNodes.length;
for(var i:Number = 0;i<listEntries;i++){
broName =
broList.firstChild.childNodes[0].childNodes[0].childNodes
.childNodes[0].nodeValue;
trace(broName);
comicTeams_list.addItem(broName);
//to make something happen when you click on a name in the
List, create a Listener and function
var broListListener:Object = new Object();
broListListener.change = someAction; //"someAction" is a
function to be written shortly
//add the Listener to the List
comicTeams_list.addEventListener("change", broListListener);
function someAction(evtObj:Object):Void{
var pickedBrother:String = evtObj.target.selectedItem.label;
//write actions here, referencing pickedBrother variable
The names of the Marx Brothers will appear in the box.
This is written in AS2. When you post a question, it's a good
idea include which version of ActionScript you're using.

How to Populate Internal table data to Table Control in a Report Program

Dear All,
       How to Populate Internal table data to Table Control in a Report Program? It is a pure report program with out any Module pool coding involved, which is just used to display data. Till now it is being displayed in a report. Now the user wants the data to be displayed in a table control. Could someone tell me how to go about with this.
Thanks in Advance,
Joseph Reddy

If you want to use a table control, you will need to create a screen.
In your report....
start-of-selection.
perform get_data. " Get all your data here
call screen 100. " Now present to the user.
Double click on the "100" in your call screen statement. This will forward navigate you to the screen. If you have not created it yet, it will ask you if you want to create it, say yes. Go into screen painter or layout of the screen. Use the table control wizard to help you along the process. It will write the code for you. Since it is an output only table control, it will be really easy with not a lot of code.
A better way to present the data to the user would be to give it in a ALV grid. If you want to go that way, it is a lot easier. Here is a sample of the ALV function module. You don't even have to create a screen.
report zrich_0004

How to populate fields "DocEntry" and "DocNum" in UDT? Those are not UDF.

I created a UDT with document type. When I populate the data, I don't know how to populate fields "DocEntry" and "DocNum". Those are not UDF. Here is my coding. Can somebody help me out?

                    objUserTable = objSBOAPI.oCompany.UserTables.Item("AIT_POSTRANS")

                        objUserTable.UserFields.Fields.Item("U_ShpBrnch").Value = objRecord.Fields.Item(1).Value.Replace("'", "")

Currently versions of the SDK (SBO2005A SP01, SBO2007A, SBO2005B, SBO2007B) does not support Data Support of UDO-tabeles using the DI-API... That means that you can only add data to such tables using the GUI,,,
This is currently a huge problem and the number one DI-API Development Request. The status with SAP is that this will become part of the SDK in SAP Business One 8.8 (the next major release), but 8.8 does not yet have a shipment date (My guess is that it will be 2009 before we even see it in rampup)...
I know some people have experimented with writing direct SQL to such tables and know it can be done, but be aware that SAP does NOT support it!... Personally I've never done it for that reason althoug it would have been nice to do if some situations...
Sorry I could not give anything better...

How to populate a sharepoint 2010 list from the active directory. How to populate a sharepoint 2010 list with all sharepoint user profiles

How to populate a sharepoint 2010 from the active directory.
I want a list of all the computers in the active directory,
another one with all users.
I want also to populate a sharepoint 2010 list from the sharepoint user profiles.
Thanks
sz

While
the contacts list is usually filled out for contacts that are outside the company, there are times when you would use a contacts list to store internal and external resources. Wouldn’t it be nice if you didn’t have to re-type your internal contacts’
information that are already in the system? Now you can with a little InfoPath customization on the contacts list.
Here’s our plan:
Create the contacts list, and open in InfoPath
Create a data connection to the User Profile web service
Customize the form adding some text, a people picker and a button
Create InfoPath rules that will populate the contact fields from the user fields in the User Profile store
Let’s get going! Before we begin, make sure you have InfoPath 2010 installed locally on your computer. I also want to give credit Laura
Rogers and Darvish Shadravan’s book Using
Microsoft InfoPath 2010 with Microsoft SharePoint 2010 Step by Step. I know it looks like a lot of steps, but it’s easy once you get the hang of it.
So obviously we need a contacts list. If you don’t already have one, go to the SharePoint site where it will live, and create a contacts list.
From the list, click the List tab on the ribbon, then click Customize form:
So now we have our form open in InfoPath 2010. Let’s add our elements to the form.
Above all the fields, let’s add some text instructing users what to do with the the field we’re about to add (.e.g To enter an existing user’s information, choose the user below).
Insert a people picker control by clicking the Person/Group Picker control in the Controls section of the ribbon. This will add a column to the contacts list called group.
Below the people picker, insert a button control from the same section of the ribbon as above. With the button still highlighted, click the Control Tools|Properties tab on the ribbon.
Then in the Label box, change the text to something more appropriate to our task (e.g. Click here to load user data!).
You can drag the button control a little larger to account for the text.
We should end up with something like this:
Before we can populate the fields with user data, we need to create a connection to the User Profile Service.
Add a data connection to the User Profile Service
Click the Data tab on the ribbon, and click the option From Web Service, and From SOAP Web Service.
For the location, enter the URL of your SharePoint site in the following format – http://<site url>/_vti_bin/UserProfileService.asmx?WSDL. Click Next.
Note - for the URL, it can be any SharePoint site URL, not just to the site where your list is.
For the operation, choose GetUserProfileByName. Click Next.
Click Next on the next two screens.
On the final screen, uncheck the box for “Automatically retrieve data when form is opened”. This is because we are going to retrieve the data when the button is clicked, also for performance reasons.
Now we need to wire up the actions on our button to populate the fields with the information for the user in the people picker control.
Tell the form to read the user from the people picker control
Click the Home tab on the ribbon.
Click the button control we created, and under the Rules section of the ribbon, click Manage Rules. Notice the pane appear on the far right.
In the Rules pane, click New –> Action. Change the name to something like “Query and load user data”.
Leave the condition to default (none – rule runs when button is clicked).
Click the Add button next to “Run these actions:”, and choose “Set a field’s value”.
For Field, click the button on the right to load the select a field dialog. Click the Show advanced view on the bottom. At the top, click the drop down and choose the GetUserProfileByName
(Secondary) option. Expand myFields and queryFields to the last option and highlightAccountName. Click ok.
For Value, click the formula icon. On the formula screen, click the Insert Field or Group button. Again click the show advanced view link, but this time leave the data
connection as Main. Expand dataFields, then mySharePointListItem_RW. At the bottom you should see a folder called group (the people picker control we just added to the form). Expand this, then pc:Person,
and highlightAccountId. Click Ok twice to get back to the Rules pane.
If we didn’t do this and just queried the user profile service, it would load the data of the currently logged in user. So we need to tell the form what user to load the data for. We take the AccountID field from the people
picker control and inject into the AccountName query field of the User Profile Service data connection.
Load the user profile service information for the chosen user
Click the Add button next to “Run these actions:”, and choose Query for data.
In the popup, for Data connection, click the one we created earlier – GetUserProfileByName and clickOk.
We’re closing in on our goal. Let’s see our progress. We should see something like this:
Now that we have the user’s data read into the form, we can populate the fields in the contact form. The number of steps to complete will depend on how many fields you want to populate. We need to add an action step for
each field. I’ll show you one example and then you will just repeat the steps for the other fields. Let’s update the Job Title field.
Populate the contact form fields with existing user’s data
Click the Add button next to “Run these actions:”, and choose “Set a field’s value”.
For Field, click the button on the right to load the select a field dialog. Highlight the field Job Title.
For Value, click the formula icon. On the formula screen, click the Insert Field or Group button. Click the Show advanced view on the bottom. At the top, click the
drop down and choose theGetUserProfileByName (Secondary) option. Expand the fields all the way down until you see the Value field. Highlight it but don’t click ok, but click the Filter
Data button, then Add.
For the first dropdown that says Value, choose Select a field or group. The value field will be highlighted, but click the field Name field
under PropertyData. Click Ok.
In the blank field after “is equal to”, click in the box and choose Type text. Then type the text Title.
Click ok until you get back to the Manage Rules pane. The last previous screen will look like this.
We’re going to update common fields that are in the user’s profile, and likely from Active Directory. You can update fields like first and last name, company, mobile and work phone number, etc. For the other fields, the
steps are the same except the Field you choose to update from the form, and the very last step where you enter the text will change. Here’s what the rules look like when we’re done:
We’re all done, good work! You can preview the form and try it now. Click Ctrl+Shift+B to preview the form. Once you’re satisfied, you can publish the form back to the library. Click File –> Quick
Publish. Once it’s done, you will get confirmation:
Now open your form in SharePoint. From the contact list, click Add new item. Type in a name, and click the button and watch the magic happen!
