Hi,

You can try like this,

Suppose if you want to provide F4 help for MATNR then

write AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_MATNR.

And provide F4 help values to that field.

within this event put one flag like W_FLAG = 1.

Initially W_FLAG =0. So when user enters his

own value in that field then the value of W_FLAG = 0.

If selects F4 help then value of W_FLAG becomes 1.

When user executes the report then check the value of W_FLAG .

If it is 0 then give a message. And also don't forget to make the field input disable after entering the value. So that he can't be able to change the value in that field again.

parameters:
  p_matnr like mara-matnr.
data: 
  w_flag type i.
  
AT SELECTION-SCREEN ON VALUE-REQUEST FOR
 
 P_MATNR.  
  W_FLAG = 1.

 CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
   .........

* check condition in at selection-screen event
AT SELECTION-SCREEN.
   if sy-ucomm eq 'ONLI'.
      if W_FLAG ne 1.
         message 'Please select from F4 help' type 'E'.
      endif.   
   else.
     PERFORM PRINT_OUTPUT.
    endif.

Regards,

Rajitha.

You can do it in Four ways.

1. You can take the reference of data element which has Search help assigned to it.

Code Below.

Parameters: p_lifnr type lifnr.

select-options: s_lofnr for lfa1-lifnr.

2. You can take reference type like below.

parameters: p_lifnr type lfa1-lifnr. or any field.

3. you can create Search help for that field through SE11 and assigned this to ur select options or parameters.

see code below.

PARAMETERS: p_zloc type zloctno MATCHCODE OBJECT zlocation,

here Zlocation is Search help object.

4. You can do it in Program itself.

data: int_fdoc type standard table of x_fdoc,

int_return type standard table of ddshretval.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_fdoc.

Select Field for F4 help.

SELECT <Filed> FROM <Table name> INTO TABLE<Internal table >WHERE <As per ur reqt comndition>

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = '<Fieldn ame>'

value_org = 'S'

TABLES

value_tab = int_fdoc

return_tab = int_return

EXCEPTIONS

parameter_error = 1

no_values_found = 2

OTHERS = 3.

IF sy-subrc = 0.

GET CURSOR FIELD ws_field.

READ TABLE int_return INTO wa_return INDEX 1.

IF sy-subrc = 0.

p_fdoc = wa_return-fieldval.

ENDIF.

CLEAR wa_fdoc.

ENDIF.

Hope This will help u lot.

you can make use of the "DISPLAY" parameter of the FM "F4IF_INT_TABLE_VALUE_REQUEST", pass the value for the "DISPLAY"

as "F"(Force Display) and disable(SCREEN-INPUT = 0) the input for the field using LOOP AT SCREEN in AT SELECTION-SCREEN OUTPUT event.

Hi ,

In that case i suppose u need to make the screen filed in display mode .

if it is in input mode then he can enter any value of his choice sometimes wrong value also .. and that needs to be validated again in pai ..

So inorder to make the user to choose from a set of fields only then either u can have a list drop down which is advised if the entries are say less in number or make the field disabled but providing the f4 func'ty.

selecting the list entry and moving it to screen field ..

Br, vijay..
