Question

I want to put a select condition on the  source fields? how can i declare that ?  like we can declare for looking up from master data tables for example
SELECT COUNT( * )
INTO <variable>
FROM /BIC/XXXXX
WHERE 0employee = SOURCE_FIELDS-employee.
How can I declare?
Thanks in advance..!

I guess I'm not quite sure what you're asking...If you're asking for the code inside the LOOP statement in the Start Routine, then it would be:
LOOP AT source_package
  ASSIGNING <source_fields>.
  SELECT
    count( * )
  INTO
    l_cnt
  FROM
    /bic/xxxxx
  WHERE
    employee = <source_fields>-employee.
  IF sy-subrc EQ 0.
    <source_fields>-rec_cnt = l_cnt.
  ELSE.
    CLEAR <source_fields>-rec_cnt.
  ENDIF.
ENDLOOP.
Or, are you looking for code in a Characteristic Routine, where you'd map 'employee' to the count Key Figure?
SELECT
  count( * )
INTO
  l_cnt
FROM
  /bic/xxxxx
WHERE
  employee = source_fields-employee.
IF sy-subrc EQ 0.
   result = l_cnt.
ELSE.
  CLEAR result.
ENDIF.
