auto complete using if_wd_select_options

[Former Member]

Hi Experts,

I have a query regarding the field i_suggest_values parameter

in ADD_SELECTION_FIELD method of interface IF_WD_SELECT_OPTIONS.

Is it similar to the auto complete feature we have newly introduced

in wd?

If so how can we implement the auto complete feature using this

method. I am not able to find any documentations for this particular

parameter.

Thanks

Hi Tenzin,

Yes you are right this is something similar to the newly introduced auto complete feature in Web Dynpro. I just tried checking the same from my end and it works like a charm

Hi Uday,

I have already got that part.

After I added the follwing url parameter, it worked in my case.

WDACCESSIBILITY = off

WDALLOWVALUESUGGEST = X.

Thanks any ways.

Hi Tenzin,

You can try the below mentioned method, we use it this way.

data fld type  IF_WD_SELECT_OPTIONS=>T_SELECTION_SCREEN_ITEM.

data tbl type  IF_WD_SELECT_OPTIONS=>TT_SELECTION_SCREEN_ITEM.

fld-m_id = 'ID'.

fld-mt_range_table = LT_RANGE_TABLE.

fld-m_read_only  = abap_true.

insert fld into table tbl.

WD_THIS->M_HANDLER->ADD_SELECTION_FIELDs(tbl).

Hopefully, this will solve your probs.

Hi Pranav,

I am using the add_selection_field method as mentioned earlier.

of the interface IF_WD_SELECT_OPTIONS.

It doesn't have a importing parameter of type IF_WD_SELECT_OPTIONS=>TT_SELECTION_SCREEN_ITEM

as you have mentioned earlier.

however I see a parameter I_SUGGEST_VALUES, even though i set it to true, I am not able to get the auto fill on the ui.

Thanks

Hi Tenzin,

For the auto fill to work the field would need to have a search help to be attached to it. When the user starts to key in a value into the input field the system does in the background pass in the value to the importing parameter of the search help & show the EXPORTING values of the search help as possible suggestions for the user.

I guess in your case there is no search help available at data element level for the field which you are trying to add using add_selection_field( ). So you would have to explicitly link one to the field. This you can do by using the 2 parameters I_VALUE_HELP_TYPE & I_VALUE_HELP_ID of the same method. You can pass in IF_WD_VALUE_HELP_HANDLER=>CO_VH_TYPE_BACKEND to I_VALUE_HELP_TYPE for indicating that you want to attach a dictionary search help to the field and then can pass in the actual search help name to the other parameter I_VALUE_HELP_ID.
