How to give a value range in export parameter (global class)

Question

hi all,
I have created a class-method called get_po_date. In this i had export parameter as qmfe-qmnum. If i give qmfe-qmnum in import parameter in class, i am able to give only one value at one time, but i need a range of values at a time. Instead of qmfe-qmnum in associated type, i have given 'LXHME_RANGE_C12' ( a range table for char 12 ). the thing is i wanted to select this range in select-options. but still iam getting <b>not type compatible syntax error</b>. can any body solve my problem,
feel free to ask if any confusion with my question.
Best Regards,

Hello Abhilash
Instead of using a specific range (where field LOW and HIGH are of type QMNUM) you can use a <b>generic </b>select option (of type <b>RSDSSELOPT</b>). Have a look at the following sample report <b>ZUS_SDN_SELOPTIONS</b>.
*& Report  ZUS_SDN_SELOPTIONS
REPORT  zus_sdn_seloptions.
TABLES: qmfe.
DATA:
  gt_data          TYPE STANDARD TABLE OF qmfe,
  gt_data_x        TYPE STANDARD TABLE OF qmfe,
  gt_selopt        TYPE rseloption,  " generic table type for selopts
  gs_selopt        TYPE rsdsselopt.
START-OF-SELECTION.
  SELECT        * FROM  qmfe INTO TABLE gt_data
         WHERE ( qmnum BETWEEN '000000000001' AND '000000000500' ).
  gs_selopt-sign   = 'I'.
  gs_selopt-option = 'BT'.
  gs_selopt-low    = '000000000001'.
  gs_selopt-high   = '000000000500'.
  APPEND gs_selopt TO gt_selopt.
  SELECT * FROM qmfe INTO TABLE gt_data_x
    WHERE ( qmnum IN gt_selopt ).
  IF ( gt_data = gt_data_x ).
    WRITE: 'Selected data are equal.'.
  ELSE.
    WRITE: 'Selected data are NOT equal.'.
  ENDIF.
END-OF-SELECTION.
Since RSDSSELOPT and RSELOPTION are global DDIC objects they can be used in <i>public </i>methods.
