Refresh selection screen (select-options)

Former Member — Tue, 30 Jun 2015 10:19:53 GMT

Hi,

Please guide me on this: i have a selection screen with few fixed select-options and few dynamic options.

i want to clear all selection screen variables .

I am reading all selection screen variables using FM

CALL FUNCTION 'RS_REFRESH_FROM_SELECTOPTIONS'

EXPORTING

curr_report = sy-repid

TABLES

selection_table = itab1. -> all variables got in itab1.

Now, i want to clear all select-options and parameter which are captured in itab1.

i saw somewhere that FM RS_SELECTIONSCREEN_UPDATE can be used for this.

But i tried .may be i am mistaken somewhere. Please guide me if this is the right FM to refresh selection screen variables and if yes how to use it?

Hi Abhishek,

By clear you mean erase all the data in the select option right? Did you try REFRESH itab1[] and see if it is refreshed?

Hi abhishek,

Why can't we try with simple clear statement once you fill the selection screen data in Itab.

Check whether Itab is initial or not initial.depending on this you can simply write the statement clear.

clear : P_var1,s_var1.

itab1[] contains names of variables only. not the exact values that user entered on selection screen.

So, refreshing itab1 not serves any purpose.

Suppose there are 5 select-options select-options are there on selection screen:

select-options1

select-option2

select-options3

select-options4

select-options5.

User entered multiple values (say 50) in each of them. now itab1 will only contain 5 values i.e name of selection screen variables.

I can't write p_var1 or s_var1 because most of the selection screen variables are dynamically created.so at run time i dont know their names.

That why i am using FM :

CALL FUNCTION 'RS_REFRESH_FROM_SELECTOPTIONS'

EXPORTING

curr_report = sy-repid

TABLES

selection_table = itab1. -> all variables got in itab1.

Now , itab1 containes all the variable names and now i need to refresh each variable.

something like this,

loop at itab1.

refresh(itab1-selname). => itab1-selname will contain the name of select-option S_VAR1 so i need to write something like Clear S_VAR1[]. dynamically!

endloop.

SELECT-OPTIONS: s_uname FOR sy-uname.

DATA: l_string TYPE string.
FIELD-SYMBOLS: <dyn> TYPE any.

l_string = 's_uname' && '[]'.
ASSIGN (l_string) TO <dyn>.
CLEAR <dyn>.

It is used only for F4 events on selection screen. According to FM documentation and where-used list:


This function module allows you to supply values to any fields of the
standard selection screen in the
AT SELECTION-SCREEN ON VALUE REQUEST.... event.
