Reset ALV User settings

Question

Hi,
I have defined an ALV dynamicly. When I add a new column to the ALV it is not displayed. Doing right click and going to 'user settings' I see that the column is added to 'Hide column'. Changing this manually shows that the new column is presented in the ALV.
This only happend if I had once clicked the user settings and did some things and SAVED. So somewhere my user settings are stored.
My question:
- How can I reset my ALV user settings in webdynpro  in a way that new defined columns are directly presented ?
- Where are these ALV user settings stored ?
Hope you can help.
Cheers, John

HI John,
As sarbjeeth suggested, get the variant(personalisation info) details from the WD application wd_analyze_config_user.
Run this application and search for the variants of the component SALV_WD_TABLE(ALv component), identify your variant and note the details like config name,config variant, config type etc.
Then in the WDDOINIT , you can try deleting like this.
DATA lo_api_controller TYPE REF TO if_wd_controller.
  DATA lo_pers_manager   TYPE REF TO if_wd_personalization.
  data lv_variants       type WDR_PERS_VARIANTS.
  data lv_config_key     type WDY_CONFIG_KEY.
  data lv_bool           type wdy_boolean.
*   get personalization manager
  lo_api_controller = wd_this->wd_get_api( ).
  lo_pers_manager = lo_api_controller->get_personalization_manager( ).
lv_config_key-CONFIG_ID = '29A71D1A8C9565ED7315B87A8CC21C94'. "These details are got from     the wd_analyze_config_user application
lv_config_key-CONFIG_TYPE = 07.
lv_config_key-CONFIG_VAR = 'ENX0N9'.
CALL METHOD lo_pers_manager->delete
  EXPORTING
*    scope                     = 1
    config_key                = lv_config_key
*    transport_personalization =
*    trkorr                    =
  receiving
    success                   = lv_bool.
Thanks,
