Field exits - is the exit called wherever the data element is used?

Since field exits are at the data element level - does this mean that the field exit will be executed for any screen that uses it?  i only have one screen that I want this exit to be called - do I control that when creating the field exit?  Or do you not have any control over that?
Thanks!
Scott

No. Field exit will not be called where ever the data element is used. When you create the field exit, you create it for a perticular field in a screen only. So effectively the exit will be triggered only for that field.

  • In AP invoice i need to make "Terms date " field to calculate the date automatically when i select the payment terms

    In AP invoice i need to make "Terms date " field to calculate the date automatically when i select the payment terms.
    How can i do this?

    Hi,
    You can select the Payment Term at PO Header Level.
    When you book an invoice, that Payment Term will automatically defaulted to Invoice.
    You can define Payment Term in AP.
    Payment terms have one or more payment terms lines, each of which creates one scheduled payment. Each payment terms line and each corresponding scheduled  payment has a due date or a discount date based on either a specific day of a month, such as the 15th of the month, or a number of days added to your terms date, such as 14 days after the terms date.

  • Is an assigned value to an variable in the domain of the data element

    Hi
    how can I check if the value, which I want to assign to an variable is in the domain of the data element of that variable.
    Example:
    I defined a data element myDataElement. The Elementary Type of myDataElement is the Domain myDomain.
    myDomain has the Format: Char with Length 1 and the fixed values 'A' and 'B'.
    The following code works, but IMHO should not:
    DATA testVar TYPE myDomain.
    testVar = 'Foo'.
    The value of testVar is now: 'F' .
    As 'F' is not in the fixed values, this is a behaviour which I don't want. How can I prevent this from not happening (without using a bunch of IFs)?
    In such a case, it were nice if an exception were raised.
    Regards
    Gilles

    Thanks Gungor.
    I tried it with DDUT_DOMVALUES_GET. Works so far. I think I will write some FMs on my own, like this one:

    *"     REFERENCE(IV_DOMAINNAME) TYPE  DDOBJNAME
    *"     REFERENCE(IV_EVALUATING_VALUE) TYPE  ANY

    *"     REFERENCE(EV_DESTINATION) TYPE  ANY
    *"  EXCEPTIONS
    *"      ILLEGAL_INPUT
    *"      NOT_IN_DOMAIN
      DATA domainvalues TYPE TABLE OF dd07v.
      CALL FUNCTION 'DDUT_DOMVALUES_GET'
        EXPORTING
          name          = iv_domainname
        TABLES
          dd07v_tab     = domainvalues
        EXCEPTIONS
          illegal_input = 1
          OTHERS        = 2.
      IF sy-subrc <> 0.
        RAISE illegal_input.
      ENDIF.
      DATA oneline TYPE dd07v.
      LOOP AT domainvalues INTO oneline.
        IF oneline-domvalue_l EQ iv_evaluating_value.

  • How to change the Text  description on screen...(not the Data Element)

    I want to change the just text of one of the label on one of the screen. I don't want to change the Data Element, as the same data element is used in multiple places, but I want to change only at one particular screen, at one particular spot
    Any suggestion....?

    a)If you change the Text in a LABEL manually, then translation of the text can't be done.
    Better create a new structure which will be used in all such cases where u can't change the data element.
    Create fields in the Structure with your newly created data element and refer the field in the Label.
    b)IF the translation is not an issue then manually enter the text.

  • How to automate the data load process using data load file & task Scheduler

    Hi,
    I am doing Automated Process to load the data in Hyperion Planning application with the help of data_Load.bat file & Task Scheduler.
    I have created Data_Load.bat file but rest of the process i am unable complete.
    So could you help me , how to automate the data load process using Data_load.bat file & task Scheduler or what are the rest of the file is require to achieve this.
    Thanks

    To follow up on your question are you using the maxl scripts for the dataload?
    If so I have seen and issue within the batch (ex: load_data.bat) that if you do not have the full maxl script path with a batch when running it through event task scheduler the task will work but the log and/ or error file will not be created. Meaning the batch claims it ran from the task scheduler although it didn't do what you needed it to.
    If you are using maxl use this as the batch
    "essmsh C:\data\DataLoad.mxl" Or you can also use the full path for the maxl either way works. The only reason I would think that the maxl may then not work is if you do not have the batch updated to call on all the maxl PATH changes or if you need to update your environment variables to correct the essmsh command to work in a command prompt.

  • How can i write the data to PIC16F819 using labview?

    how can i write the data to PIC16F819 using labview?
    Need help!
    im using labview in gathering the datas that i need to right to the PIC, then after getting all the datas i am using another program which is ICD2 in order to write it to the PIC. Is it possible to do this task through LV? coz we are spending a lot of time transferring the data from LV to ICD2 manually and its prone to mistake as well.
    any suggestion?
    thanks,
    Pedz

    LabVIEW does not currently have a built-in method to communicate with
    i2c, but there are other vendors that sell devices to communicate in
    this manner with LabVIEW development kits.  One that I know of is
    from MCC... here is a link:  http://www.mcc-us.com
    They sell a device called iPort, and then you can buy LabVIEW VIs to go with it.  I hope this is helpful to you!

  • Getting error while using the data element in ztable

    though i specified the length as 20 in dataelement when i am entering the dataelement i am getting this error
    while i used help i got the following information
    Number of positions < minimum number (1) for data type CHAR
    Message no. DO253
    Diagnosis
    A minimum length is required for the specified data type.
    This minimum length is not reached by the specified number of positions.
    Procedure
    Increase the number of positions or select a more appropriate data type with the possible entries help F4.

    This is strange, you shouldn't even be able to activate the dataelement type char with a length of 0. Revisit your data element and make sure that the length shows to be greater than 0 and reactivate your data element to make sure the newest version is active. In case you are referencing a domain in your data element do the same with the domain after validating that everything is correct (you can also use the check function). Then go back to your table and reenter the data element before activating your table.
    Hope that helps,

    How to write the data into EEPROM using Labview?

    You would need some sort of EEPROM programmer. Typically might
