RSA3 gets results - but InfoPackage not!

Question

Hey all,
we got the following problem:
We are using a generic datasource which is extracting data from two database-views with help of a function block we derived from the SFLIGHT-example.
The extraction is working well in RSA3 and we do get the results we expect.
But as soon as we replicate the datasource in the myself-system (we tried both 3.x and 7.0 datasource) and do execute and InfoPackage exactly using the same selection as in RSA3, we don't get any results!
Where shall we locate the potential failure? I already deleted the datasource several times and replicated it anew - but without any success...
Would be great if someone could give us some hints!
Thanks in advance,
bivision

Hi,
yes, I've done that but I don't know yet how to run debugger out of SM50. Could you explain this to me, plz?
Update on the issue itself:
Like I mentioned, we are using an input variable for a 0FISCPER selection and we are goinig through CONVERSION_EXIT_PERI7_INPUT' with it. I did now remove the 0FISCPER-selection and did set a constant value in code for it - and there, the IP worked and delivered the requested values!... Probably there is something wrong with the ConversionExit?
We are going like this in the function module:
LOOP AT s_s_if-t_select INTO l_s_select WHERE fieldnm = 'DATETO'.
      CALL FUNCTION 'CONVERSION_EXIT_PERI7_INPUT'
       EXPORTING
       input           = l_s_select-low
        IMPORTING
           output          = lv_akt_monat
       EXCEPTIONS
          input_not_valid = 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.
       IF lv_akt_monat+4(3) = '012'.
         lv_year = lv_akt_monat(4) + 1.
                   CONCATENATE lv_year '001' INTO lv_vormonat.
        ELSE.
          lv_vormonat  = lv_akt_monat + 1.
        ENDIF.
  ENDLOOP.
