Selections on DataSource with a Function Module

Question

Hello Experts,
I need your help, we have a DataSource with FM and this does not filter the records by the values that we select. For example: we select 01 to 03 in field Period (PERAF) in the result the extractor show all values whitout consider the filter.
I don't know ABAP but I think it's a simple adjustment in your code.

Hi
It is a custom function module... Then part of the code...
  134  * Fill parameter buffer for data extraction calls
  135      s_s_if-requnr    = i_requnr.
  136      s_s_if-dsource = i_isource.
  137      s_s_if-maxsize   = i_maxsize.
  138
  139  * Fill field list table for an optimized select statement
  140  * (in case that there is no 1:1 relation between InfoSource fields
  141  * and database table fields this may be far from beeing trivial)
  142      APPEND LINES OF i_t_fields TO s_s_if-t_fields.
  143
  144    ELSE.
  145
  146      LOOP AT s_s_if-t_select INTO l_s_select WHERE fieldnm = 'GJAHR'.
  147        MOVE-CORRESPONDING l_s_select TO l_r_gjahr.
  148        APPEND l_r_gjahr.
  149      ENDLOOP.
  150      LOOP AT s_s_if-t_select INTO l_s_select WHERE fieldnm = 'ZANLN1'.
  151        MOVE-CORRESPONDING l_s_select TO l_r_afijo.
  152        APPEND l_r_afijo.
  153      ENDLOOP.
  154
  155      LOOP AT s_s_if-t_select INTO l_s_select WHERE fieldnm = 'PERAF'.
  156        MOVE-CORRESPONDING l_s_select TO l_r_perz.
  157        APPEND l_r_perz.
  158      ENDLOOP.
  159
  160
  161 
  162      pyear =  l_r_gjahr-low.
  163 
  164
  165      IF s_counter_datapakid = 0.
  166
  167 
  168
  169        CLEAR: t_a_c, e_t_data, t_traslado.
  170        REFRESH: t_a_c, e_t_data, t_traslado.
  171        ayear = l_r_gjahr-low - 1.
  172 
  173 
  174 
  175
  176
  177        OPEN CURSOR WITH HOLD s_cursor FOR
  178     SELECT a~bukrs gjahr izwek anlue umwkz kansw knafa ndabj answl nafap
  179                            aanln1 aanln2 anlkl ord42 deakt gjahr afabe
  180                            ord43 aaibn1 aaibdt aktiv aibn1 aibn2
  181                            FROM anla AS a INNER JOIN anlc AS c
  182                            ON abukrs = cbukrs AND
  183                            aanln1 = canln1
  184                            AND aanln2 = canln2
  185                            WHERE a~bukrs = 'HCVN'
  186 *
  187 *
  188 *
  189 *
  190 *
  191 *
  192*
  193*
  194                               AND c~afabe = '01'
  195                               AND gjahr IN l_r_gjahr
  196                               AND a~anln1 IN l_r_afijo.
  197
  198
  199      ENDIF.
I very much appreciate you help
