How to change the width of a field?

Hi all,
I would like to decrease the width of a field on my report.
But I can't do it in the Property palette. I am not able to change the width property. The width of the database column is varchar2(255). I do not want to decrease the length of the database column, but only the width property of the field.
Any ideas?
Regards

As far as I knows, you can only increase the width of a
character column. If you wish to decrease it, I would think
you'd have to drop/delete the whole column and recreate it,
loosing all your data in the process (unless you create a
temporary table into which you copy the data first, and then
copy it back into the "new" column - the oracle db will truncate
the data automatically).
SQL Plus is very well suited for the task, but requires you to
write the appropriate SQL statements yourself. Other tools may
simplify this for you (I use SQL Plus myself).
Hope this helps.

  • How to change the lenth of existing field in sap standard table

    Hi all,
    can anybody help,my requirement is, how to change the length of existing field in sap standard table....
    thanks in advance..

    Which field are you thinking of in particular?  Are you wanting to increase or decrease the length?
    Some fields are used so extensively that a change to their length will mean adjusting many tables, some of them potentially very large, and hence taking a long time to adjust.
    Some standard SAP programs expect certain fields to be of specific lengths and won't work if the length is changed.
    Some screens could cease to work.
    If you decrease length, then you could lose data.

  • How to change the width of PDF report

    When i download an interactive report to a PDF. All the columns will have the same width, how to change the width of the column?
    Thanks,
    Jen

    I don't think its possible for downloading from interactive report but let's see if anyone else has got a work around.
    The other way to have absolute control over report layout is to create reports using 'Report Query' & 'Report Layout' under 'Shared Components'.

  • How to change the width of a switch control?

    If I set long on&off texts, they can't be fully displayed. How to change the width of this sap.m.switch control?
    P.S., "width" attribute doesn't work here.

    Hi Jocy,
    A switch is just a simple boolean control : true/false, yes/no, on/off. Other possibilities are not possible.
    If you to need to choose between, say, black/white, then a switch is *not* a good choice; nothing stops you from adding yellow/red/blue to the mix as well.
    If you *do* have a strict boolean choice (again, only rue/false, yes/no, on/off) then I would suggest adding a descriptive label with the simple, short switch control.
    Otherwise, I would strongly advice using a different type of control (RadioButtonGroup, DropdownBox)

    First use the Active Cell property and set the row value to -2 to change an entire column. The attached image shows how to set the background color of column 3 to green. I don't understand your comment about column size. It doesn't matter how wide or narrow a column is. Using the Cell Background Color property, the entire cell is colored. If you are having difficulty keeping track of the number of columns, thats a different issue.

    Hi,
    Can you please tell me how to change the width of dropdown parameter's in BI Publisher

    Kirk,
    In the <rw:graph> tag, just add the standard HTML properties of width="xxx" and height="xxx" to control the width and height of the image. BTW, the graph tag is in the on-line help, although not in the index. You can find it by doing a search for "rw:graph".

    You can't change that from where you are trying because that info is coming from the database. To resize the field just open the layout editor and size the field to the size you want.

  • Change the width of a field using XML

    Hi,
    I customize a report -set the width of a field- using XML but my
    data is truncated.
    Is it posible to set vertical elasticity for this field using
    XML?
    My XML file is:
    <?xml version="1.0"?>
    <report name="Rep" DTDVersion="1.0">
    <layout>
    <section name="main">
    <field name="F_1" source="CP_FIELD" textColor="red" width="0.5"/>
    <field name="F_2" source="CP_FIELD" width="0.5"
    alignment="center"/>
    <field name="F_3" source="CP_FIELD" width="1"/>
    </section>
    </layout>
    </report>
    I will appreciate any suggestion.
    Thank you

    You can change the size of the label, the text input box, and the field itself (border around the field in the design tab) - however there is one exception to being able to control the size of every field individually:
    Fields that have "Labels left" or "Labels right" that are also the first field in a row will all share the same label width.
    This is probably what you are encountering, this is how the fields work for now, those first in a row label left/right labels are all the same width.
    Thanks,

  • How to change the width of the whole portlet layout?

    Dear all,
    As we know, now the width of portlet layout has set to 100%. But there is a new requirment from my customer that the width of the whole portlet layout view must be set to 750px.
    So I tried to edit the css file and I found a block:
    #pt-portal-content-view
         margin-top: 0px;
         width: 100%;
    I tried to change the width to 750px, but nothing happened.
    I want to know the way to change the width, thank you all!
    Regards,
    finall
    OK,I have found the place to do it:
    .portalContent          {
         display: block;
         width: 750px;
    I set to 750px,then it works.:-)
    But another question, how to make the content align to the center? I tried a stupid method, add margin-left:
    .portalContent          {
         display: block;
         width: 750px;
         margin-left: 120px;
    In 1024 X 768, it's ok, but it don't work well in 800 X 600.
    When I set the all content width to 750px, I tried the three columns view, the portlet still run over the border.If there is any way to control this? thank u in advance!
    Regards,
    finall
    Edited by finall1980 at 02/01/2007 10:09 PM

    Try this:
    .portalContent {
    display: block;
    width: 750px;
    margin: auto; /* for properly-implemented browsers */
    text-align: center; /* for IE 6 */
    As for running over the 750px, there's nothing you can do about that other than actually narrowing the columns AND making sure that your portlet authors don't produce content that's too wide.
