ALV doesn't sort as expected.

Question

Hi,
I created sorting rules for two columns, document number and date. Each different date of a certain document constitutes a line in ALV. I used the following code to set the rules. However, the ALV doesn't sort as expected.
LOOP AT LT_FIELDS INTO LS_FIELDS.
     CASE LS_FIELDS-FIELDNAME.
       WHEN 'AUFNR'.
         LO_SORT_RULE ?= LS_FIELDS-R_FIELD->IF_SALV_WD_SORT~CREATE_SORT_RULE( SORT_POSITION = 1 ).
         LS_FIELDS-R_FIELD->IF_SALV_WD_SORT~SET_GROUPING_ALLOWED( ).
       WHEN 'ISSUE_DATE'.
         LO_SORT_RULE ?= LS_FIELDS-R_FIELD->IF_SALV_WD_SORT~CREATE_SORT_RULE( SORT_ORDER    = IF_SALV_WD_C_SORT=>SORT_ORDER_DESCENDING
                                                                              SORT_POSITION = 2 ).
         LS_FIELDS-R_FIELD->IF_SALV_WD_SORT~SET_GROUPING_ALLOWED( ABAP_FALSE ).
       WHEN OTHERS.
     ENDCASE.
   ENDLOOP.
The result is
Header 1
Header 2
001
20140101
003
20140103
006
20140104
002
004
005
But I expect the ALV to be sorted as follows
Header 1
Header 2
001
20140101
002
003
20140103
004
005
006
20140104

Hi ts,
The above code used for sorting should work as you expected.But I suspect that the sort logic of field 'AUFNR'  is not executing / not reaching. Check the column name of HEADER1 column. It might be something else.
To make sure: check in debugging that the logic of AUFNR field gets reached.
Hope this helps you.
