MESSAGE I000(0) WITH 'enter the values between 1000 and 2000'. RAISE EVENT ZEVENT_METHOD. ENDIF. *provide select statement SELECT * FROM LFA1 INTO TABLE IT_LFA1 WHERE LIFNR BETWEEN S_LIFNR_LOW AND S_LIFNR_HIGH. *transfer the values to another internal table IT_LFA11 = IT_LFA1. ENDMETHOD.
After that provide the logic in se38. REPORT ZCL_EVENT_OPERATION . *provide data objects DATA: LFA1 TYPE LFA1, OBJ TYPE REF TO ZCL_EVENT_OPERATION, IT_LFA1 TYPE Z_LFA1, IT_LFA11 TYPE Z_LFA1, WA_LFA1 TYPE LFA1. *provide select statement SELECT-OPTIONS: S_LIFNR FOR LFA1-LIFNR. *provide create object START-OF-SELECTION. CREATE OBJECT OBJ. *call the method CALL METHOD OBJ->METHOD_EVENT EXPORTING S_LIFNR_LOW = S_LIFNR-LOW S_LIFNR_HIGH = S_LIFNR-HIGH IT_LFA1 = IT_LFA1. *provide attribute value IT_LFA11 = OBJ->IT_LFA11. *display the data LOOP AT IT_LFA11 INTO WA_LFA1. WRITE:/ WA_LFA1-LIFNR, WA_LFA1-LAND1, WA_LFA1-NAME1, WA_LFA1-ORT01. ENDLOOP. Save it, check it, activate it and execute it. Then the output is like this. If lifnr value is 2000.
