HOW TO CHANGE LENGTH ATTRIBUTE OF AN STANDARD ITEM?

we need to set appropiate "display" lenght to an item (VO attribute) in a standard OAF page.This item has maximum length=30 but length (to display)=25 . This is not acceptable for our customers because they can't see the complete value of the item
To see the item (Project Name):
Project Manager resp.--> Project List
Choose a Project.
CLick on Setup Page
There, it appears project information. One of the items is Project Name (Name).
As I said before, this item has maximun length =30 but displays only 25 characteres wide in the "box". Most of items have the same number in both of their properties, but not this.
How could we change it?
(of course respecting standards)
Page is : BasicInformationPG.xml
it is in /oracle/apps/pa/project/webui
I'm trying to see where to modify the attribute length while I'm extending the VO.
I mean:
I create in JDeveloper a VO (ProjectBasicInfoVO) extending the original.
I edit VO and go to Attributes... and I see that "Type" property for "Name" attribute is VARCHAR2(30). But.. 30 is not the number of characters we can see in the screen... so How could I change the "length" property of "Name" attribute while extending the VO?
Please, provide detailed steps. Sorry, I don't see so easy as you say ...

OAF questions should go into the OAF forum.
In general you can use the UI control hints for the attribute to set its display width.

  • How to change general attribute of text element

    hi
    who now how to change general attribute of text element on screen dinamically? I wish to change text value dinamically for example.

    Hi Denis,
    I am not too sure on what you want.
    If you require that the text value be different based on some conditions you can declare as many text elements as conditions and call the relevant text element.
    But I dont think that you can assign dynamic texts to a single text element.

    for example `
    How to set an ICON on my GUI BUTTON in the program?
    so what's the mapping between CONTROL in the SCREEN PAINTER and variable in the program?

    Hi Chao Liu,
    Ya , u first find out the PF-STATUS of the screen and goto that status and now u can modify the ICON u want .
    Finding the GUI status of the screen
    Goto that  TRANSACTION CODE or SCREEN
    On the Standard Menu bar Goto ( Menu path) System --> Status
    Now u get a pop-up System :status in that in SAP Data block u can find GUI Status. Now Double Click on that Status. It takes u to the Status of that screen.
    Now click on the Display --> Change Button on the application tool bar.
    If it is a standard GUI-status then it asks for the ACCESS KEY.
    if it is a custom defined GUI Status  then u can change the status .

  • How to change the attribute name for a relation

    When the Data Modeler engineers a logical model into a relational model it create table columns for the relations. The names of the generated columns are listed in the attributes list in the properties dialog of the relation. The actual name of the attribute gets calculated by the attribute name of the entity which is part of the relation. This is okay, if there is only one relation between two entities. But when there are two relations between two entities the second attribute gets a stupid number suffix. This makes it impossible to give the attribute a useful semantic meaning.
    When I engineer the model into a relational model I can change the column name in the relational model. Changing the column name in the relational model is not perfect but it would be okay for me, if it would not be overwritten during the next engineering run.
    So I have two questions:
    How can I change the attribute name in the attributes section of the properties dialog of a relation? See here for screen shot:
    http://public.ceving.de/2012050300/relationattribute.png
    And if it is not possible:
    How can I preserve any changes on column names in the relational model during a re-engineering run?
    Edited by: 931739 on 03.05.2012 08:07

    Hi,
    I've logged an Enhancement request on this.
    I don't believe it's possible to change it from the Entity or Relationship dialog, as it's not updatable in these dialogs.
    What you can do is change it in the Relational Model, and then reverse engineer the change back to the Logical Model.

  • How to change length of line in Photoshop CS3

    I must be being really stupid, but I can't find out how to change the length of a line I've drawn in PS using the line tool. Can anyone help me out?

    Which type of line did you draw?
    Filled pixels, Shape Layer or Path?
    If filled pixels, then it's just like with any other pixelsyou have to erase them, or or make a selection and delete them. To lengthen, you'll have to use the Transform function.
    If you created your line as a Shape Layer or as a plain path, they are both defining the line as vector elements. If you look very closely, you'll see that the line is actually a thin rectangle-shaped patha boxif you will.
    In this case you can use the Path Selection Tool to select two of the anchor points and move them manually, or you can select the entire path and then use the Transform Path function (Command + T) and input values in the Options Bar to transform the points numerically.

    Hi Manish,
    You may write the Formcalc scripting for the respective field.
    //Check ISR control parameters for read/write access
    if($record.CONTROL_PARAM.ISR_MODE == "DISPLAY" |
       $record.CONTROL_PARAM.ISR_FORM_VIEW =="ISR_APPROVE" | <b>$record.CONTROL_PARAM.ISR_REVIEW == "true" )</b>

  • How to change the  attribute of screen field to drop down list dynamically

    Hi All,

      A                        input field
      B                       drop down list
    This is a tabular disply where the Screen field attribute for Col y  is NO DROP DOWN BOX.
    My requirement is to change the attribute of COl Y to DROP DOWN list depending on the value of
      COL X  dynamically.

    Dear Ajay,
    Actually this requirement is to enhance the standard screen for Tcode :EHSVU21.
    So depending on the 1st Column(Test no)  value ,i have to change the 3rd Column(Low.norm.result)
    property either to DROP Down or not.
    So in the PBO only the changes to be made and there is no field in SCREEN internal table for changing the attribute to DROP down. I checked SCREEN internal table where the field VALUE_HELP and REQUEST is useful but not  suitable for my case.
    Any solution available?

  • How to change cn attribute

    How can I change 'cn' using Oracle Directory Manager?
    The 'cn' attribute is normally grayed out, so cannot be changed.
    Thanks,
    Chetan

    Hi Chetan:
    What you are trying to do is modify the RDN (Relative Distinguished Name). The following is an example of how to change the RDN from "cn=dcp1" to "cn=thanh mai". The example assumes the entry to be changed resides under "dc=Americas, dc=IMC, dc=com"
    ldapmoddn -p 389 -h host_name -D cn=orcladmin -w welcome -b "cn=dcp1, dc=Americas, dc=IMC, dc=com" -R "cn=thanh mai"
    This modifies the RDN component of the DN from "cn=dcp1" to "cn=thanh mai"
    Hope this helps.
    Thanks,

    Edited by: david on Sep 6, 2011 11:56 PM

    There is something I don't understand here. Why do you need to point at the sxd? What is changing? Like I mentioned before. If the contents of the xsd change, all the report will do is - at best - drop the changed fields so you will be missing data. Perhaps some of the following will help;

  • Flex 3 - How to change an attribute name ?

    like this
    <item code="1" />
    to
    <item id="1" />
    thanks

    Hi Alex,
    You can use setName to change the attribute name:
    Here for example change all your id attributes with code:
    var xmlTest:XML=<r><item id="1"/></r>;
    for each (var node:XML in xmlTest.item.descendants("@id"))
    node.setName("code");
    trace(xmlTest);

  • How to change View Attribute Name?

    Is there a way to change the attribute name of a view object that was added from and entity Object?
    I dont want to change the Entity Attribute Name since i want to use it in diferent view objects with diferent names...

    Hi Frank
    It would be very convenient to have view object attribute name updateable because the attributes may result from different joins (to same table) and have different meaning depending more on the association than to the table attribute itself (in most case the relationship extend the meaning of the attribute).
    In my use case i have :
    A table FlexTypologyClassMatrix with two foreign key pointed to FlexTypologyClass primary table. That mean that my matrix have two axis defined by the primary key of FlexTypologyClass table.
    I created a view object that correspond to this scheme with eo's FlexTypologyClassMatrix, FlexTypologyClass as FlexTypologyClassAxisX, FlexTypologyClassAxisY).
    The view object attributes from eo's FlexTypologyClassMatrixAxisX or Y are generated from the table attribute name with a suffix like FlextypologyclassL (for FlexTypologyClassMatrixAxisX) and FlextypologyclassL1 (FlexTypologyClassMatrixAxisY).
    The attribute name are the most used item used later in the development cycle and this is not easy to distinguish the X from the Y without analyzing the view object definition. It's not a very productive way to develop application.
    It would be very convenient to permit the view object attribute name to be updateable or the alias name of the entity object in the view object has to be displayed with, every time.
    I didn't check if the info is displayed every tiem, may be it is a workaround !?
    Hope you understand what I mean. Thank you.

  • How to change the attributes of an XML file

    hi peeps 'ope you can help me here i need to change the attributes of an xml file, i parse it first using a DOM parser but i cant find a way to change the attributes in the XML file, setAttribute() works only at runtime and doesn't change the attribute in the file itself. I can't find a method that will answer my question. I've searched through the forum and found similar threads....they say in order to write and change the attribute i must use the write() method of the XmlDocument class defined in com.sun.xml.tree.XmlDocument. But, i found another thread, and it says that com.sun.xml.tree.XmlDocument is not safe to use and i should use org.apache.crimson.tree.XmlDocument.....i can't find the XmlDocument class and the API for this package so i really dont know where to start...hope you guys can help me! thnx

    thanks for responding roland....i already found the solution...i didn't use the XmlDocument class because i can't find any documents about it except for JAXP 1.0 here is my code snippet...i used the TransformerFactory and Transformer class to write

    e1 = (Element) n1;
    NodeList nodeList = doc.getElementsByTagName ("File");
    //just insert whatever you want to do with the XML...parse it..set/change the attribute..etc....sample snippet below changes the attribute downloaded to "no"
    for(int iWriteFailed = 0; iWriteFailed <nodeList.getLength() ; iWriteFailed ++){     
    n2 = nodeList.item(iWriteFailed);
