Dropdownbykey. data is missing in one column

Hi,
I am facing issue in dropdownbykey UI element.
When pushbutton is clicked, there is table showing up. but the first column in the table is missing. There is no value. This column values are expected to be like hyperlink so that when any one is clicked that is selected and the field is populated by this value.
I have found the dropdownbykey UI element on the view and trying to find the code for this UI element.
I dont know anything about the dropdownbykey ui element as i am new to web dynpro. I am reading the sap help material but its not addressing very basic understanding
Could you please help get answers to following
1) When we click pushbutton of dropdownbykey ui element we see a table from which we can click on one of the rows (only one column of the table is link which we can click) How are the columns in the table determined ?
2) Which key of the table is selectable ?
3) From where are the values of the table fetched ? u2013 backend.  so obviously will have to pick data type linked to the ui element from some model rite ? it cant be string.
4) Why is there a value-set ? is it for the dropdown part of the ui element ? is it mandatory to code them as contants when we make a ui element dropdownbykey on our view or there is any other way of fetching this value-set data?
thank you

Hi Yogesh,
Its perfectly alright.
Could you please tell me what is SVS code ?
Is it so that by using this I will have all the methods needed for coding required for dropdownbykey ui element ?
I dont want to go by dropdownbyindex because I am not developing any application, there is this problem in an already developed application which I have to investigate
My above questions were based on understanding that when we include dropdownbykey ui element in our view , the dropdown list, pushbutton and screen with all values are inbuilt. This is written in the sap help on the link -
http://help.sap.com/saphelp_nw04/helpdata/en/5c/1b76bc3da0504e8b535cf3e154eaa7/frameset.htm
But now I have seen in my system that there is actually a separate view for displaying values is created for the pop up.
there is linktoaction ui element in the view where the dropownbykey is put and this linktoaction calls the view for displaying values.
I am now checking inside the code which passes data to this pop up view , why the first column in the table is missing.
thanks

  • Upload data from excel where one column has text of 3000 characters

    Guyz,
    I have a query. One of my requirments is to upload data from excel sheet & create a material. In the excel sheet one of the columns has text for BASIC DATA TEXT under ADDITIONAL DATA of a Material. This is a text of running length.
    the selection screen has feature of file upload & the users will upload excel files from their respective presentation servers.
    Now my problem is that I need a function module which can convert this column in excel sheet into an internal table & later call the BAPI for MM creation.
    I have used TEXT_CONVERT_XLS_TO_SAP & when i read my internal table to check this column length, it shows only 255 characters where as data in the excel sheet has 3000 characters (say for eg.)
    Can anybody throw some light on this.
    Thanks in advance
    GPK

    Hi,
    You can try using this function module and see that whether all your data is coming into the internal table properly.
    MS_EXCEL_OLE_STANDARD_DAT
    For the other part you needed to convert the internal table data into the structure as need by the BAPI and then call the create BAPI to create the materials in the SAP System.
    Hope this helps.
    Thanks,

  • When I save a PDF as an Excel File, all of the data in the PDF is put into one column (AdobeXI)

    Hi, thanks for taking the time...
    I'm running a machine with Windows 7, Office 2010, and Acrobat XI.  When I save a specific PDF as an Excel workbook, all of the data in the original PDF is sorted correctly in four columns.  When the same task is performed on this file on another user's machine, all of the data is sorted into one column.  The user has the same versions of Windows, Office, and Acrobat.  I've attempted the "Repair installation" option but the problem persists.  Any suggestions?  Thanks again for helping,
    -E

    Thanks for the quick reply.  I figured out how to get the desired results by using tagging.  For anyone who may reference this post in the future, I went to "Customize" in the top right corner of Adobe, then selected "Create new tool set...", looked under "accessiblity and found the "tag" option.  Hit ok, tag is added to the toolbar.  Then I highlighted the dataset in the PDF that was relevant to the output format, then clicked "tag", saved as spreadsheet.  Sorry I can't provide more details on how tagging works or if there's a more elegant solution available, but I'm sure one's out there.

  • Need to return a cell value in a row where a date was selected from a column

    I'm looking for a formula for OS Numbers and can't seem to find it.
    I use the MIN function to select the earliest date in a range of cells.  The dates all flow down one column.  I need to be able to have numbers return the contents of a cell in the same row that was selected as the earliest date.
    For example:
    ID
    Exp. Date
    3
    4
    LJ-1
    May-2014
    LJ-2
    Jun-2014
    LJ-3
    Jul-2014
    LJ-4
    Aug-2014
    LJ-5
    Sep-2014
    I need to search for the earliest date in the 'Exp. Date' column and once it finds it, return the value from the 'ID' column.
    So, in this case, i would need a formula to find May-2014 and return LJ-1 to the cell.
    Any help would be greatly appreciated.

    Hi 86,
    Rearrange your table then add another table to find the result:
    A2 in Table 1-1 will find the earliest date in Table 1 without having to sort Table 1.
    A2 contains this formula
    =MIN(Table 1::A)
    B2 in Table 1-1 uses VLOOKUP to find which ID matches that MIN date.
    The reason for rearranging your table (Table 1) is that VLOOKUP compares a search value to the values in the leftmost column of a specified collection.
    (in this case, it looks in the leftmost column of the range Table1::A:B, then returns a match from column 2 of that range).
    I forgot to include "Exact Match" in the VLOOKUP formula. Is that what you want, or "Close Match"?
    Edit: I don't suppose that matters because MIN will always give an exact match. Duh!
    Regards,
    Ian.

  • Variable Data Set has only one thing but the error asks for more

    Hi -
    I have a PSD (CS5, Win7) where I've defines 5 layers with variable names. One of them is the Heading layer with the variable named varHeading.  The Data Set I'm importing is very simple in that only the Heading layer will change. I'm gone over the construction of this text file a number of times but when I try to Import it as a Data Set I get the error:
    "Could not parse the file contents as a data set.  There were not enough variable names in the first line of the text file."
    varHeading
    "BABY CAR SEAT AECC0841"
    "BABY CAR SEAT AECC0842"
    "BABY CAR SEAT AECC0843"
    "BABY CAR SEAT AECC0844"
    "BABY CAR SEAT AECC0845"
    My first question is - does the number of variables stored in the PSD file have to match the variable names in the first line of the text file??
    If NOT - can someone please help me figure out what I'm doing wrong?
    TIA your expert input.
    j2

    When you say you have defined 5 layers with variable names are you trying to attach the data set, that has one column, to each one at the same time? Did you create the data set in the Photoshop Data Sets Dialog ? The error that you are getting pops up when you have defined more variables than you have in your data set.

  • Missing Standard Dimension Column for data load (MSSQL to Essbase Data)

    This is similar error to one posted by Sravan -- however I'm sure I have all dimensions covered -- going from MS SQL to SunOpsys Staging to Essbase. It is telling me missing standard dimension, however I have all accounted for:

    I'm using hard coded input mapping for Metric, Scenario, Version, HSP_Rates and Currencies. -> 'Amount', 'Actual', 'Final', 'HSP_InputValue','Local' respectively.
    The only thing I can think of is that since I'm loading to each of the months in the Time Periods dimension (the reversal was set up to accomodate that)... and now its somehow still looking for that? Time Periods as a dimension does not show up in the reversal -- only the individual months named above.
    Any ideas on this one??

    John -- I extracted the data to a file and created a data load rule in Essbase to load the data. All dimensions present and accounted for (five header items as similar here) and everything loads fine.
    So not sure what else is wrong -- still getting the missing dimension error.
    Any other thoughts?? Here's the entire error message. Thanks for all your help on this.

  • How can I Move data from one column to another in my access table?

    I have two columns, one that stores current month’s data and one that stores last month’s data. Every month data from column 2 (this month’s data) needs to be moved to column 1 that holds last month’s data. I then null out column 2 so I can accumulates this month’s data.
    I understand how to drop a column or add a column, how do I transfer data from one column to another.
    Here is my trial code:
    <cfquery name="qQueryChangeColumnName" datasource="#dsn#">
      ALTER TABLE leaderboard
      UPDATE leaderboard SET  points2 = points3
    </cfquery>
    Unfortunately, I get the following error:
    Error Executing Database Query.
    [Macromedia][SequeLink JDBC Driver][ODBC Socket][Microsoft][ODBC Microsoft Access Driver] Syntax error in ALTER TABLE statement.
    How can I transfer my data with the alter table method?

    I looked up the Access SQL reference (which is probably a
    good place to start when having issues with Access SQL), and
    it suggests you probably need a WHERE clause in there.
    I agree the documentation is a good place to start. But you should not need a WHERE clause here.
    Too few parameters. Expected 1.
    If you run the SQL directly in Access, what are the results? At the very least, it should provide a more informative error message..

  • OAF Export button fetching data in one column - view object using union all

    Maheswara Raju,
    As per my understanding you are not able to export all the View Attribute using export Button. Only the attribute which is used with the item/region will get exported.
    There are few work around in case if you want to export the column without showing on OAF Page. Let me know.

  • [Forum FAQ] How to configure a Data Driven Subscription which get multi-value parameters from one column of a database table?

    Introduction
    In SQL Server Reporting Services, we can define a mapping between the fields that are returned in the query to specific delivery options and to report parameters in a data-driven subscription.
    For a report with a parameter (such as YEAR) that allow multiple values, when creating a data-driven subscription, how can we pass a record like below to show correct data (data for year 2012, 2013 and 2014).
    EmailAddress                             Parameter                      
    Comment
    [email protected]              2012,2013,2014               NULL
    In this article, I will demonstrate how to configure a Data Driven Subscription which get multi-value parameters from one column of a database table
    Workaround
    Generally, if we pass the “Parameter” column to report directly in the step 5 when creating data-driven subscription.
    The value “2012,2013,2014” will be regarded as a single value, Reporting Services will use “2012,2013,2014” to filter data. However, there are no any records that YEAR filed equal to “2012,2013,2014”, and we will get an error when the subscription executed
    on the log. (C:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\LogFiles)
    Microsoft.ReportingServices.Diagnostics.Utilities.InvalidReportParameterException: Default value or value provided for the report parameter 'Name' is not a valid value.
    This means that there is no such a value on parameter’s available value list, this is an invalid parameter value. If we change the parameter records like below.
    EmailAddress                        Parameter             Comment
    [email protected]         2012                     NULL
    [email protected]         2013                     NULL
    [email protected]         2014                     NULL
    In this case, Reporting Services will generate 3 reports for one data-driven subscription. Each report for only one year which cannot fit the requirement obviously.
    Currently, there is no a solution to solve this issue. The workaround for it is that create two report, one is used for view report for end users, another one is used for create data-driven subscription.
    On the report that used create data-driven subscription, uncheck “Allow multiple values” option for the parameter, do not specify and available values and default values for this parameter. Then change the Filter
    From
    Expression:[ParameterName]
    Operator   :In
    Value         :[@ParameterName]
    To
    Expression:[ParameterName]
    Operator   :In
    Value         :Split(Parameters!ParameterName.Value,",")
    In this case, we can specify a value like "2012,2013,2014" from database to the data-driven subscription.
    Applies to
    Microsoft SQL Server 2005
    Microsoft SQL Server 2008
    Microsoft SQL Server 2008 R2
    Microsoft SQL Server 2012

    For every Auftrag, there are multiple Position entries.
    Rest of the blocks don't seems to have any relation.

    Through a select i want the output of my data in one single
    columns, Well I can do this by using union.
    But my output should be like
    if I select by condition where A=2
    my output should be
    2
    1
    3
    7
    4
    because all these numbers are linked with 2 how do i do this
    because it is like searching the number 2 in two columns and wherever this number 2 is linked i should get all the data relevant to it.

  • Query to get the data of all the columns in a table except any one column

    Can anyone please tell how to write a query to get the data of all the columns in a table except one particular column..
    For Example:
    Let us consider the EMP table.,
    From this table except the column comm all the remaining columns of the table should be listed
    For this we can write a query like this..
    Select empno, ename, job, mgr, sal, hiredate, deptno from emp;
    Just to avoid only one column, I mentioned all the remaining ( 7 ) columns of the table in the query..
    As the EMP table consists only 8 columns, it doesn't seem much difficult to mention all the columns in the query,
    but if a table have 100 columns in the table, then do we have to mention all the columns in the query..?
    Is there any other way of writing the query to get the required result..?
    Thanks..

    Your best best it to just list all the columns. Any other method will just cause more headaches and complicated code.
    If you really need to list all the columns for a table because you don't want to type them, just use something like...

  • Download file format(different length data on one column)

    Hi all,
    i am just writing a report to download the delivery data to a file.the file have 3 columns.the length of the column data in every row varies.
    let my file structure is like
    first line of my file contains,
    delivery no(22),delivery date(8),delivery type(5)
    2nd line of the file contains,
    shipper num(48),customer PO num(20),material num(15)
    In the first column of this file contains delivery number(length-22)& shipper number(length-48).but the length of both the data will be different i.e i have to assign the length of delivery num as 22 & length of shipper num as 48.but they will appear in one column. how it will be possible.
    is there any command to make the file format like this?
    ur help is highly appreaciated.it's urgent.
    Regards
    pabitra

    whatever record you will populate(i mean it may be either delivery no or shipment no etc..)define your internal table with the highest length(in this case 48).
    as both values are CHARacters, there is no problem even if you populate Delivery no(of 10 chars) to 48 char field.
    spaces will be truncated.
    data:begin of itab,
    col1<b>(48) type c</b>,
    col2,
    col3,
    end of itab.
    *--when you are populating Delivery no:
    ITAB-COL1+0(10) = V_DELIVERYNO.
    CONDENSE ITAB-COL1+0(10) NO-GAPS.
    *--when you are populating SHIPMENT no:
    ITAB-COL1+0(48) = V_shipment.
    CONDENSE ITAB-COL1+0(48) NO-GAPS.
    i guess,there wont be any problems,if you use this logic.

  • When I import a text file(comma separated )into a numbers spread sheet all the data goes into one column. Why does the text not go into separate columns based on the commas.

    When I import a text file(comma separated) into a numbers spreadsheet all the data goes into one column instead of individual columns based on the comma separators.  Excel allows you to do this during the import..  Is there a way to accomplish this in numbers without opening it in Excel and the importing into Numbers.

    Your user info says iPad. This is the OS X Numbers forum. Assuming you are using OS X… Be sure the file is named with a .csv suffix.
    (I don't have an iPad, so I don't know the iOS answer.)
