Get column Disable

Dear All,
I have created table control field wa_itmdtls-ebeln with input field posible. when user is entring single po no and he press enter then below wa_itmdtls-ebeln column gets disable. I want User can enter multiple PO number and pressing multiple time enter.
I have tried with
    READ TABLE tabl_ctrl-cols INTO wa_col INDEX 4.
    wa_col-screen-input = 1.
    MODIFY tabl_ctrl-cols FROM wa_col INDEX 4.
under PROCESS AFTER INPUT, MODULE user_command_9010.
Please provide appropriate solution.
Thanks
Regards,

Hi try this way...
PROCESS BEFORE OUTPUT.
* Module screen GUI-Screen&Status and Screen Logic
MODULE status_1020.
* Table control for OUTPUT
LOOP AT <table name>
       WITH CONTROL <table control>.
    MODULE screen_modify.
ENDLOOP.
MODULE SCREEN_MODIFY OUTPUT.
* Table control reading values from input screen & displaying on screen
if <tablecontro>-current_line = 4.
READ TABLE tabl_ctrl-cols INTO wa_col INDEX 4.
IF sy-subrc = 0.
    LOOP AT SCREEN.
      IF screen-name = 'WA_ZCXREF_CLASSES-ATWRT'.
        screen-input = 0.
      ENDIF.
      MODIFY SCREEN.
    ENDLOOP.
ENDIF.
endif.
ENDMODULE.

Why do I get a class conflict between the Prepare SQL.vi and the Get Column Name.vi with the SQL Toolkit compatibility vis from the Database Connectivity Toolkit?

I have done extensive programming with the SQL Toolkit with LabVIEW versions through 6.1. My customer now wants to upgrade to Windows 7, so I am trying to upgrade to LabVIEW 2009 (my latest purchased version) using the Database Connectivity Toolkit, and the SQL Toolkit Compatibility vis. Everything seemed to be going okay with the higher level SQL operations, but I ran into trouble with the Get Column Name.vi.
The pictures below show the problem. The original SQL Toolkit connected the Prepare SQL.vi with the Get Column Name.vi with a cluster of two references, one for connection, and one for sql. The new compatibility vis have a class conflict in the wire because the Prepare SQL.vi contains a cluster with connection, and command references, but the Get Column Name.vi expects a cluster with connection and recordset references.
How do I resolve this conflict?
Thank You.
Dan

I've never worked with the old version of the toolkit, so I don't know how it did things, but looking inside the SQL prep VI, it only generates a command, and the the column name VI wants a recordset. I'm not super familiar with all the internals of ADO, but my understanding is that is standard - you only have the columns after you execute the command and get the recordset back. What you can apparently do here is insert the Execute Prepared SQL VI in the middle and that will return what you need.
I'm not sure why it worked before. Maybe the execute was hidden inside the prep VI or maybe you can get the column names out of the command object before execution. In general, I would recommend considering switching to the newer VIs.
Try to take over the world!

How to get column header text in IWDTable

Hi
Just want to know how to get column header name in IWDTable.
I know that you can get it with
IWDAbstractTableColumn[] groupedColumns = table.getGroupedColumns();
for (int i = 0; i < groupedColumns.length; i++) {
     IWDAbstractTableColumn column = groupedColumns<i>;
     column.getHeader().getText();
But what if text isnt set on header level but its rendered from cellEditor model binding (im not sure if its like that).

Finally after your suggestion i did it with this code
String header = column.getHeader().getText();
                   if ((header == null || header.length() == 0) && column instanceof IWDTableColumn){
                        IWDTableCellEditor tableCellEditor = ((IWDTableColumn) column).getTableCellEditor();
                        if (tableCellEditor instanceof IWDTextView){
                             String bindingPath = ((IWDTextView)tableCellEditor).bindingOfText();
                              StringTokenizer tokenizer = new StringTokenizer(bindingPath,".");
                              String token = "";
                              IWDNodeInfo nodeInfo = context.getNodeInfo();
                              while (tokenizer.hasMoreTokens()){
                                   token = tokenizer.nextToken();
                                   if (tokenizer.hasMoreTokens()){
                                        nodeInfo = nodeInfo.getChild(token);
                              IWDAttributeInfo attribute = nodeInfo.getAttribute(token);
                              ISimpleType simpleType = attribute.getSimpleType();
                              simpleType.getDescription();
                             header = simpleType.getDescription();

Getting users disabled/deleted with disabled resources in OIM

Hi,
Consider following use case related to OIM:
To get the Users deleted or disabled on a particular date with their 'AD User' resources which are in disabled state.
By means of built in reports i can get the users disabled or deleted for particular date.... how do i get the disabled AD User resource for each user....
i can go for scheduler task but how to proceed on that?

the exact requirement here is to get the users/deleted a day before along with their 'AD User' resources which are disabled
getObjectsByTypeStatus(long plUserKey, java.lang.String psObjectType, java.lang.String psStatus)
Gets a list of all the objects of the specified type that have been provisioned for a user and are in the specified status.
What i can make out here is that:
i need to write some logic that would give users disabled/deleted say yesterday... after this i would loop in these user keys into getObjectsByTypeStatus that would give resources disabled for each user.
Am i correct?
Now how do i get the users disabled/deleted yesterday. This is realised by default Users Disabled/Users deleted report.
But how do i use it in my scheduler

HT201352 Tried everything and still get ipod disabled on screen Help please if possible

I have tried to reset and erase and all the things online and I still get ipod disabled on the screen I don't know what is wrong Can someone offer a different suggestion

Disabled
Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
iOS: Forgot passcode or device disabled
If recovery mode does not work try DFU mode.
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: Back up and restore your iOS device with iCloud or iTunes
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
If problem what happens or does not happen and when in the instructions? When you successfully get the iPod in recovery mode and connect to computer iTunes should say it found an iPod in recovery mode.
If you previously turned on FIndMyiPod on the iPod in Settings>iCloud and wifi is on and connected go to iCloud: Find My iPhone, sign in and go to FIndMyiPhone and use Remote Wipe to erase the contents of your device. If you have been using iCloud to back up, you may be able to restore the most recent backup to reset the passcode after the device has been erased.
You can also wipe the iOS device by installing the FindMyiPhone app on another iOS device and using that app to wipe the device.

Excisable Column Disabled

Hi Experts,
Previously i was using SAP B1 2005B PL40. But now i have upgraded to SAP B1 2007B PL10.
Now in 2007 B PL10 i am facing a problem. In the SO, Delivery & A/R Invoice template the Excisable Column is Inactive.
Even in the form setting i have checked , it is showing the Visible column as enable but the Active column is disable.
Is there any idea of SAP behind this change. If not then guide me how to make the Excisable Columns as Active in the SO, Delivery & A/R Invoice template.
Thanks and Regards,
S Manikandan

Getting column names using EJB3.0

Hi,
Could someone help me how to get column names in EJB3.0.
I am having reference to folloiwng ejb.
@Entity

@org.hibernate.annotations.Entity(dynamicInsert = true, dynamicUpdate = true)
@SequenceGenerator(name = "users", sequenceName = "users")

private Long userId;
private String username;
@Id
@GeneratedValue(strategy = GenerationType.AUTO, generator = "users_seq")
@Column(name = "user_id")
public Long getUserId() {
return userId;
public void setUserId(Long userId) {
this.userId = userId;
@NotNull
@Column(name = "username")
public String getUsername() {
return username;
public void setUsername(String username) {
this.username = username;
Thanks in advance

You shouldn't be getting column names from EJBs.
You need to know the object, the schema, and how to map one to the other.
So you should look at the SQL table "users" and map this object to it.

Stored Procedures - Get Column Information

Hello,
I recently switched from ODP Unmanaged to ODP Managed (I'm using Entity Framework).
The Unmanaged drivers were working fine after adding the necessary information in the web.config section. I could add the stored procedures and generate the complex types using the Function Import - Get Column information.
After the switch the config section was updated and it all appeared to work. By the way the changes in the format of the config-section is poorly documented - to say the least.
However when I try to generate the complex types again I just get a "System.notSupportedException" (Message: The specified type is not supported by this selector).
Was this functionality not ported to the Managed Drivers? Is there something that can be done to enable this functionality?

The implicit ref cursor config file format is different between Unmanaged ODP.NET and Managed ODP.NET.
To save yourself from pulling your hair out, do the following -
1) Install ODT 12.1 if you haven't already
2) Find the stored procedure in server explorer, right click it and run it, and enter input parameters.
3) For the output ref cursor that represents the return value for your Entity Function, choose "Add to Config" checkbox.
4) Then select either "Show Config" (and then cut and paste) or "Add to Config".
Here is a screenshot of what I am talking about:

You're here in a JDBC forum, not a SQL forum. I suggest you to start learning SQL and come back once you have JDBC issues.

Getting column names for a particular Table from Connection object.

Hi,
Can any one suggests me a way to get column names from a particular table of a database from the java.sql.Connection object. ?
Thanks in advance.

Connection connection;
DatabaseMetaData metadata = connection.getMetaData();
String[] names = {"TABLE"};
ResultSet tables = metadata.getTables(null,"%", "%", names);
while (tables.next()) {
String tableName = tables.getString("TABLE_NAME");
ResultSet columns = metadata.getColumns(null, "%", tableName, "%");
while (columns.next()) {
String columnName = columns.getString("COLUMN_NAME");
}
