How to compute field value in SIM

I have a form with 3 fields and 1 button. The user will populate the firstname and lastname field. When they press a button (i.e. button consists of an expression), the button script should concatenate the firstname and lastname, the result should then be shown on the 3rd field (i.e. fullname). This is to be done using XPRESS.
This seems to work if i have the script in the 3rd field, however, i am having trouble in populating the 3rd field by triggering the script using a button.

(If my memory serves me well (not used for long time ago)
Assign values to system fields sy-tvar0 - sy-tvar9, they will replace the placeholders "&0" through "&9" in the list headers and column headers.

  WRITE record-vbeln TO sy-tvar3.

  • How to add field value to the standard table

    Hi,
    How to add field value to the standard table?
    for example:
    when we go to TCODE SE16-> VBAK table -> on the selection screen if we press F4 against VBTYP we get all the available values for that field. How to add a new document Category value to this field so that it shows up in F4 help for that field.

    Hi Asif,
    I don't think it is possible and feasible for adding new field value to the field VBTYP because it is not possible through SPRO.
    If u see the domain of this field VBTYP we have fixed values provided by SAP. There is no value table for this. If u have value table then it will be updated through SPRO. But still if u really want to add some value u can do that by getting access key and add the value in the fixed values of the domain. But of no use other than simply displaying in F4. Because for what ever value u created here there will be no documents in VBAK or any table using this domain.
    Hope this is clear for u.
    Thanks,
    Vinod.

  • How to set field value in workflow SPD2013?

    Hi All,
    how to set field value in workflow SPD2013? Actually using Infopath, i need to update a field value through workflow.(Little differnt from SPD2010). How to do this?

    As Amit says, some elaboration here would be good.  You can use InfoPath as a form for either a list or a library and then set it to trigger a workflow upon item creation.  The workflow will consist a number of actions, one of which is the Update
    Field Item.
    More information on the available steps can be seen here.

  • How to pass field value from popup window to oninput processing of other pg

    Hi,
    I want to pass a field value from the popup window to oninput processing of main page ( from where popup window is triggered). and need to close the popup window. How to do it ?
    In the popup window's oninputprocessing, im doing some validation checks. If it passes all the validations, then only the control shd come to main page ..else it should stay in popup window only .
    Regards,
    Jothi.

    Hi Jothi,
    you can use java script to pass the value and close your popup window. use the following code.
    in your popup window:
    function passData(h1)
             window.opener.document.getElementById('var1').value = h1 ;
             window.close();
    then call this function when you finish your validations.
    in your main page layout create an input field with id as passed in the function above "var1".
    In the value attribute give it your variable as follow:
    <htmlb:inputField id      = "var1"
                              value   = "<%= var2 %>"
                              visible = "false" />
    "var2" will be assigned the value from your popup window.
    I hope this will help you..

  • How to display field values in long text of messages....

    Hi,
      Currently iam doing an userexit. In that i want to display error messages. and if we click on message it will display the long text. My question is i want to display field values in the long text. Under the long text's &system_response& i want  to display a field value.
    Regards
    chinna

    Hi Chinna,
    Within short and long texts, you can use placeholders, which can be replaced with the content of data objects using the MESSAGE statement. A maximum of four character-type placeholders are permitted; they are indicated by #&i# in short texts, and by #&Vi&# in long texts, where i = [1, 4]. If #&# itself is to be displayed as part of the text, it must be specified as #&&# in short texts and as "&" in long texts.
    To add some detail on how to create variables in Long text, you have to go to 'commands' and in symbol option provide the variables like
    &V1&  &V2&  and so on.
    Hope this helps you.
    revert for further clarification.

  • How to copy fields values between same class objects with filtering ?

    Hi I'm facing a problem.
    It started when thinking to the clone method for cloning objects.
    And developed into a problem when trying to making something more complicate that just cloning.
    Suppose you have two JPanels and one is a copy of the other suppose that u feed the copy to some methods for processing.
    These methods modify simple data (ints,Strings, CustomClasses) and swing components too.
    Now when I get the object back I want to copy all of the fields values to the original JPanel except for those who represent swing components or the like.
    I want to do this automatically by writing some few rows of code.
    How can I do this using reflection ?
    How can I filter the Fields objects that I get from jpanelInstance.getClass().getDeclaredFields(); ? Which metod should I use then to check if is a subclass of java.awt.Component ?
    I've read about many things on using reflection to invoke methods, constructors and so on.
    But how do I get the fields values as I get the fields objects ?
    Thanks for the attention, hope what is written is clear enough,
    Estades.

    Are you targeting a "worst design award"? What kind of "processing" would take place on a UI component?
    I am sure from what you write that you missed to seperate your model from your view. Read about MVC and retry designing your application.

    Format trigger is for change the formation of value. Like change the font, make it bold,italic, changes it's colour . Not for filtering.
    If you want to restrict your report not to show Zero(0) value of stock , you have to done it at SQL query. Like, if stock is a database filed you may write
    select .........,....
    from table
    where stock >0Hope this helps.

  • How to change field values AFTER Inbound IDOC Posted successfully

    Hi SAP Experts,
    In my project I receive the inbound IDOC PORDCR05 from PI and posted as an Purchase Order in ECC.
    I create the Z process code and Z function module (which is a copy version of IDOC_INPUT_PORDCR) and complete all the necessary configuration steps. It works perfectly.
    My problem is: I have to  collect some inbound idocs (that satisfied some criteria) and change the value of field EKPO-TXJCD and EKKN-KOSTL of the PO AFTER  it posted successfully (means the purchase order is created and save in database).
    How can I do this? I've try to put the logic code in Z function module, but it does not work, since at that time, the Inbound IDOC is not updated to the database yet.
    Aprreciate your advise.
    Regards,
    Elaine.

    Hi Elaine ,
    as per your cretiria pick the idocs and take created PO# from status 53 & use the BAPI (BAPI_PO_CHANGE) to change the neccessary values in the PO. We can't reprocess those idocs again.

  • How to restrict field values

    Hello Experts,
    I got a basic question to ask. Iu2019ve created a custom table and then attached a check table with one of its field. This field is not PK. Now through help u2018F4u2019 I can see the values coming from check table. But other then those values let say if I enter any data (any garbage) it is getting stored in the table. Can somebody tell me how to restrict this field so that user must have to select the values from the list not on his own?
    Thanks

    Do a validation of the input that the user gives.
    Select single xxx from Ztable
    where xxx ( eq selection screen parameter )
              ( IN select options )
    If Sy-subrc eq 0.
    Through an error message
    Message e000 'Pls enter a correct value for the XXX '
    Endif.
    The whole code should be under AT selection screen event.
    i guess you will agree with this solution.
    Thanks,
    Karthik
