InfoPackage OLAP variables used in the ZXRSRU01 INCLUDE - I_STEP value ?

Question

Dear All, as I am aware OLAP variables used in InfoPackage Data Selection are processed in the standard user exit (EXIT_SAPLRRS0_001) - INCLUDE ZXRSRU01 where the customer created global reporting variables are also processed when queries are run and are processed according to the value of I_STEP being 1, 2 or 3.
When processing the variables according to the running of InfoPackages the value of I_STEP in this case seems to be 0. Is this always the case for the value of I_STEP = 0 when processing according to InfoPackage?
I have meticulously searched documentation and can only find the I_STEP = 0 value when applied to Authorisation processing.
We are creating separate Includes depending on the value of I_STEP instead of having one great block of code in the ZXRSRU01 Include.
We obviously want the InfoPackage code to run only when the InfoPackage runs instead of it being checked every time a query is run.
Also is there an easier way to see where a customer variable is used:
1) rather than creating a dummy query that uses the variable to restrict a characteristic and using the right click mouse funstion to see where the varaible is used in queries? and
2) also when the variable is used in InfoPackage selection is there a transaction or feature somewhere to see where this variable is used in these selections as opposed to looking at the table RSLDPSEL via SE16 selecting on variable name
i.e is there a nice "where used" feature that shows comprehensively where a customer user exit variable is used across the board.
Thanks
Mark

Hi Sarah,
You don't need any FM for your issue.
Please try thie sample code :
DATA: VAR_INPIUT LIKE RRRANGEEXIT.
CASE I_VNAM.
  WHEN 'ZVAR2'.
   CLEAR L_S_RANGE.
   IF I_STEP = 2."PROCESSED AFTER VARIABLE INPUT
*Reading value of ZVAR1
    LOOP AT I_T_VAR_RANGE INTO VAR_INPIUT
      WHERE VNAM = 'ZVAR1'.
      CASE VAR_INPIUT-LOW.
*FILLING ZVAR2
       WHEN 0.
          L_S_RANGE-LOW     = 10.
       WHEN 1.
          L_S_RANGE-LOW     = 20.
      ENDCASE.
      L_S_RANGE-SIGN     = 'I'.
      L_S_RANGE-OPT      = 'EQ'.
      APPEND L_S_RANGE TO E_T_RANGE.
      EXIT.
    ENDLOOP.
  ENDIF.
ENDCASE.
Hope this helps
