Cheking all text items for null

hi all
we always check a text item in the trigger key-next-item as follows
if :idumitem is null then
message
end if
Now Suppose I am having 100 text items in my form
Can I check these items for null without writing code in each item's trigger
is there any procedure like clear_form ( which clears all the text items) or can v see the code of fucntion clear_form..or can v make some procedure which cheks each text item
any help will b appriciated.....

Also learn which triggers to use. You say you are using a KEY-NEXT-ITEM trigger. As far as I know that trigger only fires when you navigate to the next item with the keyboard.
This leaves many situations unchecked. It probably won't fire if you leave the item with the mouse and it probably won't fire either if you press Commit-Form while still in the item.
It looks like you are trying to do some sort of validation, which should be in WHEN-VALIDATE-ITEM (or WHEN-VALIDATE-RECORD to check the entire record at once).
Also, if you're just checking for Null values, wouldn't it be easier to just set the Required property to Yes and have Forms handle it for you?

  • Query to find all text attachments for items

    I am using the query below to try to find all active items for my org that have an attachment of type 33 (something we have defined I believe) and contain specific text. Some of the items appear to meet all criteria (active, right category, etc) but do not show up in my results.

    There is no workbook/worksheet linkage to a business area. So you cannot search for a business area and find all the workbooks "attached" to that business area. The attachment of workbooks is at the folder level. It is actually possible, if you are sharing folders among business areas, to create a workbook with data from 2 or more business areas. I have tested that and it is indeed possible. In Discoverer Administrator you can check on folder dependencies to see what workbooks use the folder. Though in my version of Discoverer, there is a problem with Discoverer Plus, such that the workbook save in Plus is not creating this dependency information like it should. At least I have not found any way to take a business area and determine what workbooks would fall under it. Maybe someone else has found a way.

  • Can I get a print out of all text messages for the past 90 days including pictures?

    Hi I am attempting to get a printout of all text message for the past 90 days to include text and pictures.  How can I do this?

    Messages + (Verizon messages app) stores up to 90 days of messages, but I think it starts when you install it - it doesn't go back prior to installation.  Other apps (SMS Backup, for one) will also allow you to save and print out your messages. Again though, I believe it only goes back as far as installation, so if you haven't been uisng the app(s), you won't have the previous 90 days available.

  • Fetching all text components for query - RSRREPDIR / RSZELTXREF / RSZELTTXT

    Hi all,
    I am developing a tool to fetch all the text components for a BI query. The texts are then to be translated and uploaded back to the BI system, but right now we are first focusing on downloading the texts.
    In the tool, the user inputs the query technical name on the screen, after which my approach is as follows:
    1) Fetch Query UID from table RSRREPDIR using Query technical name.
    2) Fetch all element UIDs from table RSZELTXREF using Query UID and by resolving the hierarchies. Agreed, the hierarchies in the table RSZELTXREF are very complex.
    3) Provide all element UIDs, including root query UID, to the table RSZELTTXT, and fetch TXTSH and TXTLG texts.
    Now, my question is at step 2: Which are the UIDs that I should fetch? Specifically, should I fetch only those UIDs which have Layout Type as 'ROW' / 'COL' / 'SHT', or should I fetch all UIDs regardless of Layout Type?
    Secondly, my understanding is that because of the table hierarchy, I should continuously feed the field TELTUID back to SELTUID until the Layout Type is 'NIL'. When this happens, I am at the Element Level. Is this correct?
    Thanks in advance,
    Shailesh.

  • How can i marge all my items for 1 shipping package ?

    Hello
    I got today the iPhone 6 and also added the new leather case and i also want to order now 2 other accessories.
    i see in my order page that the case should ship in 1 day and the iPhone as we all know will ship in the 19 of September.
    Also the 2 other items can ship in 48 hours.
    I would like , Apple to ship all the items together and not 1 by 1.
    Is there a way to marge all the orders to 1 order so it can ship together ?

    If you are replacing a device, you need to restore your new device to the backup of your old one.  If you backed up your old device to iCloud and your new device is already set up, do the following:
    Go to Settings>General>Reset on your new device and tap Erase All Conent and Settings
    Go through the setup screens on your new device and when given the option, choose Restore from iCloud backup and follow the prompts.
    Be sure your device is connected to wifi and your charger as this may take some time to finish.

  • Display the all text entered for all folder at Item and Header level of PO

    Hi everybody,
    I have the task like the following :
    In a PO there are text folders available at Header and Item level. I want POs with type Purchasing document type u2018ZFu2019 ( First Article PO ) should display all the texts entered into any of these folders either at Header level or Item level during print preview and PO output like Purchasing document type u2018NBu2019 ( Standard PO ).
    u2022 The technical information relating above subject ( SAPScript ):
    o The layout set ( form ): ZPCC_PURCHOR_STD
    o Print program : SAPLMEDRUCK
    u2022 The problems like the following :
    o I found out the differences in debugging of 2 types of Purchasing document type u2018ZFu2019 and u2018NBu2019 .
    o Only Purchasing document type u2018NBu2019 the print program processes Text Elements (HEADER_TEXT, ITEM_TEXT, SUPPL_TEXT) to display all the texts entered into any of these folders either at Header level or Item level.
    o To control the displaying of Text Elements as I know I need a print program, however, our print program is standard print program of SAP system in this case. So I can not make any changes there.
    Do we have the configuration place to this one.
    Please help me to fix the problem. Thank you in advance !

    Hi
    I advise to use the subroutine pool as your sapscript is the bespoke one ( Z one) . So you can make use of the below pseudo code.
    In the sapscript the point where you want to display the text include the following code (
    Assume that your are print header text Then first find out the Co-ordinates for it .Go to me23n->Text tab-> In change mode -> double click on text editor-> which takes you to sapscript layout->Under Go to -> Click on header & get the following details.
    Text name : ekko-ebeln
    Language : ekk-spras
    TEXT ID : F01
    TEXT OBJECT : EKKO.
    /: DEFINE &V_ID& = 'F01'
    /: DEFINE &V_OBJECT& = 'EKKO'.

    Kevin .. you are GENIUS ;)
    It worked with NAVIGABLE set property.

    I'm trying to concatenate all text items in a for loop into a varable x with the following code:

    Its equivalent to the following code:

    x := x || txt_segment_2;
    x := x || txt_segment_100;
    OR equivalent to:

  • Tabular form for text item -save changes not working

    Hello,
    I have created a tabular form in which I have made one of the columns say deptno as an Text item using APEX_TEXT.ITEM package.
    In my tabular form by default I have created it with all the buttons like with ADD ROW,CANCEL,SUBMIT(SAVE).
    My problem is that whenever I make any changes to the text item for deptno column, and then try to save the changes by clicking SUBMIT - the changes are not taking place to the deptno text item column.
    Can anyone help me out with this.
    thanks.

    hi Denes Kubicek.
    the thing is that i have made it as text item because I have concatenated it with an popup image when clicked on it opens up an new popup window
    which is a report containing dept table details. So if need to make a change to the deptno text item column in the parent window for a particular record
    then i do through the popup window (like by selecting the deptno from the popup window - so that this value is returned to my parent window deptno text item column)
    for this reason i have made the column deptno as an text item.
    can you help me out with this issue.
    thanks.

  • Chart and text items are not synchron

    hi all,
    i am a newbie in apex 4.0.
    i have two regions. the first shows a chart, based on pl/sql-code. second shows text items for possible filter an the current statement of the chart.
    when user clicks on a bar in the chart then
    1. i set the the first text item as filter,
    2. a pl/sql-code runs, build a sql statement, assign the sql statement string to the second text item and
    3. returns the statement for the chart.
    it works fine. the chart refresh. and the data i can see are correct.
    but the text items in the other region doesn't refresh.
    when i press "refresh"-button at browser level everything is fine. chart and text items fits together.
    what can I do to refresh all regions when the chart changes the sql-statment / User clicks?
    Is there any way to read out the current statement of a chart?
    thx in advance

    Bernd: the reason I asked about views is that you don't have any error messages. This might indicate that (a) you have no items in the view, or (b) there's something wrong with view-role-user assignment.
    To check for (a), please go to the published procurement catalog, and go to Views tab. Check that your View is Active. Click on your View ID link to display view details. You should see a list of characteristics assigned to your view in Assign Characteristics sub-tab (the list should not be blank!). Go to Assign Items sub-tab. Navigate in your schema to find items that are supposed to be assigned to your view. You should see "Yes" in the "Assigned" column for those products. If you don't, then you simply don't have any items in your view.
    Another thing I'd like you to check: when the user calls your procurement catalog for search, do you see the name of the catalog displayed just below the drop-down "Select Categories Hierarchically"?

  • Insert hyperlink into Text Item

    I'm looking to create a footer text item for all reports that has a link that will launch an email to the BI team.  I was able to find some javascript that I can use to launch Outlook but I can only get it to work with a button item or link item.  I can't seem to figure out how to insert it into a Text Item.
    What I want is:
    "If you have any question please contact BI Team"
    where BI Team is the link.
    Thanks.

    Hi,
    i hope you want this functionality in WAD report. have u tried "HREF" in HTML code of WAD for that link.
    for example: you want to open the link on clicking on "BI Team" so write a code in WAD like this
    "If you have any question please contact  <a href="http://mail.google.com/" target="_blank" >BI team</a>
    Hope this will solve you query

  • Transfer PO with Text Item

    Hi,
    I am not able to transfer PO with text item to GTS. The error system is throwing is "Maintain Customer product master in GTS", which i cannot do for a text item.
    Has anyone faced a similar issue?
    Regards
    Vivek

    Hello Vivek,
    you should use the enhancement:
    SLLLEG01      Legal Services: Plug-In: Customer Enhancements
    component: EXIT_SAPLSLL_LEG_CDPIR3_002  will be relevant in your case.
    to make sure that the text items are not transferred to the GTS.
    Using this enhancement you also can exclude the text items for sales orders or delivery notes if necessary.
    I recommend to create a Project with transaction CMOD where you assign all enhancements that are relevant for GTS. This will always give you a quick overview of active and available exits.
    SLLLEG01      Legal Services: Plug-In: Customer Enhancements
    SLLLEG02      Legal Services: Plug-In: Customer Enhancements: BOM
    SLLLEG03      Legal Services: Plug-In: Customer Enhancements: Preference
