Web Dynpro ALV disable column sort for specific column

[Former Member]

Hi,

I have the above mentioned problem. The Coding I use is:

DATA: lr_field_settings TYPE REF TO if_salv_wd_field_settings,

lt_fields TYPE SALV_WD_T_FIELD_REF.

FIELD-SYMBOLS: <fs_field> LIKE LINE OF lt_fields.

lr_field_settings ?= lr_config.

lt_fields = lr_field_settings->get_fields( ).

READ TABLE lt_fields ASSIGNING <fs_field> WITH KEY fieldname = 'ANSPRECH_DETAILS'.

IF sy-subrc EQ 0.

<fs_field>-r_field->if_salv_wd_sort~set_sort_allowed( abap_false ).

<fs_field>-r_field->if_salv_wd_sort~set_grouping_allowed( abap_false ).

ENDIF.

When debugging I can see that the object attributes for sort_allowed and grouping_allowed are changed from 'X' to ' '

but the running application still allows sorting and grouping for the column 'ANSPRECH_DETAILS'.

So what did I forget or what is my mistake ????

Thx for your help.

You might want to try using some methods from CL_SALV_WD_CONFIG_TABLE.

Perhalps I should have mentioned using cl_salv_wd_config_table for getting the lr_config reference:

DATA: lr_config TYPE REF TO cl_salv_wd_config_table.

I don't see any methods of this class where I can set the sorting behavior for only one specific column. Following the integrated SAP class description you have to use objects of type lr_field. You get this lr_field ref by using the lr_config ref to get it for a specific field (column). But something seems to be missing. Perhalps I have to use something like a refresh method at the end (but I tried it already and it didnt solve the problem).

DATA:

lr_if_controller TYPE REF TO iwci_salv_wd_table,

lv_refresh_in TYPE if_salv_wd_table=>s_type_param_refresh_in.

lr_if_controller->refresh( lv_refresh_in ).

(All the above coding is within the wddomodifyview Method of the relevant view)

Thx Dino Dini

Hi,

try to put the code in WDDOINIT instead of WDDOMODIFY.

Thanks,

Just tried to put the coding in wddoinit but its the same problem when using wddoinit. So same problem in wddoinit.

Thx Dino Dini

I got the similar requirement and I tried to do the below way.. it worked for me..

DATA: lr_field_settings TYPE REF TO if_salv_wd_field_settings.
DATA: lr_field TYPE REF TO cl_salv_wd_field.

lr_field_settings ?= lr_table.

lr_field = lr_field_settings->get_field( 'MATNR' ).
lr_field->IF_SALV_WD_SORT~SET_SORT_ALLOWED( abap_false

).

you can observe in the below image that sort option is not enabled for MATNR in the ALV.
