Hi,
Use FM REUSE_ALV_GRID_DISPLAY and implement the I_CALLBACK_USER_COMMAND for this as:-
I_CALLBACK_USER_COMMAND = 'USER_COMMAND'   "<--in caps
FORM user_command USING ucomm    LIKE sy-ucomm
                        selfield TYPE slis-selfield.
  CASE ucomm.
    WHEN '<function_code>'.
      "validate the entry done by user here.
  ENDCASE.
ENDFORM.
Hope this helps you.

    Hi,
    Where do you want to create this field? (Create User Form, Process Form....).
    If your requirement is to do it in the Create User Form, or Self Register or Edit Profile... You have to edit the FormMetadata.xml file. There are many posts in the forum of how to edit this file but ask if you need any help.

    Hi,
    i need to make non editable field (Price field) after requester created the shooping cart.The field should be  non editable only for requster .
    this i need to make when workflow triggers when the buyer sends  back the shopping cart to requester.
    one solution which i found:depend on the status of the shoping cart
    but i dont know whether it is correct way.
    if not please suggest me the solution.

    Hi,
    You can implement the BADI" BBP_UI_CONTROL_BADI".
    You can check for the role of the user who has logged in(e.g. for user REQUESTER,there will be a distinct role to idnetify that the user is a requester) and then acc set the display properties for the field PRICE.
    For sample code pls refer the foll links:

  • Update non-editable field Start date which is calculated from other context

    I had created some custom date fields(model, bol entity) in component ICCMP_BTSHEAD. We are calculating Start date based on the new input value into receiving date in the other context node.
    so, for this i get the value on controller class(_IMPL). and pass the same value in the GET method of Start date.
    But, Problem is Start date is the non-editable field so SET method will not be trigger as expected. so the same i used the DO_PREPARE_OUTPUT method but it's called and update the value when we press the enter. IF directly we click on the "SAVE" button then it' trigger but value is not updating in the database.

    could you please help me?

    Hi,
    Thanks for your reply,
    yes, i checked the same thing also. But DO_HANDLE_DATA is called before the SET method of receiving date and in that case we are getting the old value in DO_HANDLE _DATA and  source and Target fields both are not updating.
    I checked, if, i'll change the input field then set method of input field and then EH_ON_SAVE is called directly.
    i think, if i'll do the same modification in the EH_ON_SAVE method as i did in the DO_PREPARE_OUTPUT then it can be updated but i don't want to change the EH_ON_SAVE at this moment.
    is there any other way to update the START DATE(Display mode in the screen) which is calculate from the other context node field receiving date.

    i want to process the non-editable fields in a transaction (ME32) from the program itself. but when i am doing this it is showing error saying  '........field is not input field'.
    how to process this. pls check this.

    Hi Jay,
    The noneditable fields cannot be modified by BDC.
    But in one of our tasks,
    We followed this techinique..
    Actually 2 of the fields in second screen are not open for input if certain variable is X in 1st screen.
    Then we started that screen with Y and in this case those fields are open for input,now in second screen we modified the field as X back and saved the record..
    I am not sure whether this might help you

  • How do I take two separate non numeric fields in a acrobat form and combine the data to display in a third separate field?

    How do I take two separate non numeric fields in a acrobat form and combine the data to display in a third separate field?

    You have to use custom JavScripting to concatenate the first 2 fields. You cannot use the first 2 calculation options because they force the values of the fields to a numeric value or ignore string values.
    Possible scripts for the 3rd field are:
    event.value = this.getField("Text1").valueAsString + " " + this.getField("Text2").valueAsString;
    or
    event.value = this.getField("Text1").valueAsString.concat( " ",  this.getField("Text2").valueAsString);
    If you do not want change the separator or not show the separator when on or the other field is empty, you will need to add more code to adjust for change.
    The above scripts will also concatenate number because the field values are read as strings and not numbers.
    There is also a generalized user written function to concatenate up to 3 fields with a separator that adjust for missing data.
