Setting new cell variant for an alv table column

Question

Hi,
I want to set a new cell variant for a column. Therefore I did the following steps:
1. Create an object of CL_SALV_WD_CV_STANDARD
2. SET_KEY( 'CELLVAR1 )
3. set_cell_design([..]-goodvalue_medium )
4. SET_EDITOR( lr_alv_input_field )
After that I added the cell variant to the column by using the method "add_cell_variant".
The last step is to call method SET_SELECTED_CELL_VARIANT.
I checked my program by using get_selected_cell_variant( ) and the return string was okay.
But when the table is displayed, the new cell variant isn't working. I defined an input field as the cell editor for my new cell variant but when the table is shown, it is just text - no input possible. In addition to that the selected cell design (goodvalue_medium , step 3) isn't working. So I think the cell variant is not used.
Can you help me?
Thanks & Regards,
Hendrik

Hi
I wonder if you can help me please, I too am having issues implementing ALV cell changes in WDA?
I am basically trying to dynamically change the individual color of a cell (not the entire column or row) dependant on certain criteria. I apologies but find that you are the closest resource for any potential information. Please see screen shot below.
Currently my code is as follows:
see: www.picasaweb.google.co.uk/dave.alexander69/Pictures#5244416971466907938
data: lr_cv TYPE REF TO cl_salv_wd_cv_standard.
loop at table 1 row data
        loop at table columns
          for the date columns only...
          IF <fs_column>-id(4) = 'CELL'.
           get and set column header dates from select option user input - done
            loop at table 2 row data (table 2 contains date ranges for row concerned)
              MOVE: ls_zdata-variance TO lv_variance.
              method 1 - as in sap press WD4A -:
              lr_cv = cl_wd_table_standard_cell=>new_table_standard_cell(
                                                 view        = view
                                                variant_key = lv_variance ).
             as mentioned...
              CREATE OBJECT lr_cv.
              lr_cv->set_key( 'VARIANCE' ).
              lr_cv->set_cell_design( '09' ).
              lr_cv->set_editor( lr_input_field ).
              lr_column->add_cell_variant( lr_cv ).
              lr_column->set_cell_editor( lr_input_field ).
              lr_column->set_sel_cell_variant_fieldname( 'VARIANCE' ).
              lr_column->set_cell_design_fieldname( value = 'COLOR_CELL' ).
              lr_field = lr_table->if_salv_wd_field_settings~get_field( <fs_column>-id ).
              lr_field->if_salv_wd_sort~set_sort_allowed( abap_false ).
              the only way I get cell coloring to work - but this is for entire column?
              ls_zdata-color_cell = cl_wd_table_standard_cell=>e_cell_design-one.
              MODIFY lt_zdata FROM ls_zdata..
            ENDLOOP.
          ENDIF.
          IF <fs_column>-id = 'COLOR_CELL'.
            CALL METHOD lr_column->set_visible( EXPORTING value = '00' ).
          ENDIF.
        ENDLOOP
      ENDLOOP.
As you see I am in the dark a bit regarding cell variants and wonder if you can point me in a better direction.
Many thanks for any help,
Dave Alexander
