How to populate the ranges using FM for the SELECTs

Question

Hi,
I am still working on the FM to create a generic extractor. I went through the debugger but I am still unable to determine how the ranges are populated. RSA3 always gives me zero values for the results.
There is a RANGE statement in the sample FM and the following statements for SELECTs
  RANGES: L_R_CARRID  FOR SFLIGHT-CARRID,
          L_R_CONNID  FOR SFLIGHT-CONNID.
and...
      LOOP AT S_S_IF-T_SELECT INTO L_S_SELECT WHERE FIELDNM = 'CARRID'.
        MOVE-CORRESPONDING L_S_SELECT TO L_R_CARRID.
        APPEND L_R_CARRID.
      ENDLOOP.
      LOOP AT S_S_IF-T_SELECT INTO L_S_SELECT WHERE FIELDNM = 'CONNID'.
        MOVE-CORRESPONDING L_S_SELECT TO L_R_CONNID.
        APPEND L_R_CONNID.
      ENDLOOP.
My question is how is L_R_CONNID and L_R_CARRID populated with low and high values for the SELECT statements? I tried to find the DS 0SAPI_SFLIGHT_SIMPLE to run and see how it is set up but there is no such DS.
Would someone take the time to say something about this in  several sentences? I have my own code and it seems that it is not populating the values for the SELECTs when I debug from RSA3 when I provide the low and high values.
Would I normally populate the low and high values from the InfoPackage 'Data Selection' tab once I have implemented in BW or ready to test in BW? That would mean I have to choose those fields as selections from RSO2. Anyway, I think I have asked about this but I am hoping to get an answer to get this going...
Appreciate any replies.

Hi
Here is an example of an extractor that uses
both method's, if the InfoPackage selection exist's
it overrides the TVARV selection (which is the default).

Parameter I_PRIVATE_MODE:
Some applications might want to use this function module for other
purposes as well (e.g. data supply for OLTP reporting tools). If the
processing logic has to be different in this case, use the optional
parameter I_PRIVATE_MODE (not supplied by BIW !) to distinguish
between BIW calls (I_PRIVATE_MODE = SPACE) and other calls
(I_PRIVATE_MODE = X).
If the message handling has to be different as well, define Your own
messaging macro which interprets parameter I_PRIVATE_MODE. When
called by BIW, it should use the LOG_WRITE macro, otherwise do what
You want.
