Hi,

I got a scenario where i have a selection screen

SELECTION-SCREEN BEGIN OF BLOCK b1 .

SELECT-OPTIONS: material FOR mara-material.

Now at START-OF-SELECTION. i need to check the values entered by user in this selection screen like if same material name is entered 2 times and give me msg like that.How can i capture the vales from selection screen.

Regards,

Hi Ravi,

You will need to write the relevant code in the 'AT SELECTION-SCREEN ON material' event.

For example:

AT SELECTION-SCREEN ON material.

delete adjacent duplicates from material. "will remove duplicate entries

START-OF-SELECTION.

...

You should find plenty of resources on this forum for handling AT SELECTION-SCREEN events. Please search for them; wish you all the best!

Cheers,

Shailesh.

Hi Ravi, <li>Try this way.

REPORT ztest.
TABLES mara.
DATA l_matnr TYPE mara-matnr.
SELECT-OPTIONS: matnr FOR mara-matnr.

AT SELECTION-SCREEN.
  LOOP AT matnr .
    IF l_matnr IS INITIAL.
      l_matnr = matnr-low.
    ELSE.
      IF matnr-low = l_matnr.
        MESSAGE 'Duplicate' TYPE 'E'.
      ENDIF.
    ENDIF.
  ENDLOOP.

Thanks Venkat.O

Hi venkat,

A small correction.

The l_matnr will only be initial for the first time .

Hi execute teh code for analysing this issue ..

tables : mara.
SELECT-OPTIONS: s_mat FOR mara-matnr no-display.
data : lv_mat type char21 .
ranges  rtab for s_mat occurs 0 .


initialization.
  s_mat-low = '100-100'.
  APPEND S_MAT.

  s_mat-LOW = '100-101'.
  APPEND S_MAT.

  s_mat-LOW = '100-100'.
  APPEND S_MAT.

  s_mat-LOW = '100-101'.
  APPEND S_MAT.

  s_mat-LOW = '100-101'.
  APPEND S_MAT.

   s_mat-LOW = '100-101'.
  APPEND S_MAT.

START-OF-SELECTION.

   SORT S_MAT BY LOW.
  LOOP AT S_MAT.
    if lv_mat is initial or lv_mat ne s_mat-low.
      lv_mat = s_mat-low.
      rtab-low = s_mat-low. append rtab.
      WRITE:/ S_MAT-LOW.
    elseif s_mat-low eq rtab-low .
      WRITE:/ S_MAT-LOW, 'duplciate entry'.
    endif.
  ENDLOOP.

the write statement in ur case can be replaced by message statement .

The user can enter multiple entries in the selection screen in the low field . now better to sort this stuff before handing the sequence ..

you can check this by altering the select options table .

br,

Vijay.

It would be better to check the input at event AT SELECTION-SCREEN as opposed to START-OF-SELECTION as the message will be displayed whilst still in the selection screen. At START-OF-SELECTION this is not the case.
