SELECTION SCREEN - Intervals

[Shky]

Hi,

I have a selection screen field. I want to perform custom checks on that field.

For example I have a field as below:

Grade: _________ to ______

I enter F and A in the above fields for LOW and HIGH respectively.

As per my application A is greater than F. But as per the selection screen, it compares the ASCII values and always gives the error "Lower limit is higher than upper limit" as F is greater than A. Hence I want to use a customized check for this.

I used my own fields and did a customized check, but if I add intervals it still allows ranges in the selection pop up.

Can you please help?

Regards,

Shalini.

well that's strange .. what is the problem is you pass A to F .. i think your o/p will stillbe the same ?

why you want to do so much of coding when you cna use the normal behavior of sap.

Hi,

Thanks for the response

I understand it is the same. But the user input may keep varying. so we convert A and F to the internal values and do a check.

Also in the DB, the search would be done with (where value > A and value <F ) which would be empty. All entries in DB have grades <A and >F.

Is it possible that the results would swap automatically when low is greater than high.

This is not the only case. Grade could be A-F, 0-100, 0-10, etc.

Thanks,

Shalini.

Hi Sandeep,

I am doing all these in my own selection screen only.

Hi,

Try with the below function module in AT Selection-Screen events

RS_SELOPT_NO_INTERVAL_CHECK,

and code your validations after that.

Hi Bala Krishna,

I have added the function module in form pgrade:

AT SELECTION-SCREEN ON pgrade_h.

PERFORM pgrade.

However if I enter the ranges, it still gives me error.

Thanks,

Hi Shalini

The grade field that you have built on the selection screen must be linked with any ddic table.I mean that garde field must be existing in DDic table in which u r working.If it is existing then in the domain of that field in the value check tab you can specify the lower and upper limit.

Hope its solves ur problem.

Thanks!!

Hi,

Code that in AT SELECTION-SCREEN OUTPUT event.

SELECT-OPTIONS : s_var FOR lv_var.

AT SELECTION-SCREEN OUTPUT.

  PERFORM no_sel_option_check.

START-OF-SELECTION.


FORM no_sel_option_check .
  DATA: lt_s_option TYPE TABLE OF rsldbselop,
  lwa_s_option TYPE rsldbselop.

  lwa_s_option-name = 'S_VAR'.
  APPEND lwa_s_option TO lt_s_option.

  CALL FUNCTION 'RS_SELOPT_NO_INTERVAL_CHECK'
    EXPORTING
      program        = sy-repid
    TABLES
      selop          = lt_s_option
    EXCEPTIONS
      no_programname = 1
      OTHERS         = 2.
  IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
    WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.

ENDFORM. " NO_SEL_OPTION_CHECK
