default a value in teh input field's F4 help.. pl help

[Former Member]

Hi friends,

i have a field City in my layout.. and i m using the Dataelement standard and in the node i gave Automatic search help.

now im getting the F4 help for the city.

But when i hit F4 i can see couple of input fields like city region and desc.. these are filters in F4.

I want to make a default value in F4 help.

how can we do it?

Hi Niraja,

If you create an OVS search help then you can default some values to be displayed. You would do this in phase 1 of the OVS. Try go through the phase 1 of the below fragment. In my example I have created an OVS for an input field on my view. The user can enter a MATNR value in here and he can press F4 to search by using wildcard characters for MATNR (material number) & MAKTX (material description). Below are the 2 lines where am defaulting the values to be displayed in phase 1.

" Setting the default values to be displayed in the selection screen

ls_search_input-matnr = 'D'.*

ls_search_input-maktx = ''.*

" for the table columns of the selection list, if necessary
  types:
    begin of lty_stru_input,

      matnr type string,
      maktx type string,
    end of lty_stru_input.
  types:
    begin of lty_stru_list,

      matnr type string,
      maktx type string,
    end of lty_stru_list.

I will try this Uday, but is there any way i can use a Datadictionary Data element search help. for this?

Hi Niraja,

Am sorry but I think that the only way you can achieve the same using a data dictionary search help is by specifying a value in the "Default Value" column of the search help. May be try copy the standard search help into your custom search help & try incorporate the change. You can then specify this search help to be used against your attribute. Hope this helps.

Uday,

Sorry for late reply, I did that and its working for me .

But one thing.. when i hit F4, i can see a default value there. But can i even see the results for that defaulted value in the result result.

I mean when i click search, i m getting result. But when i hit F4, by default i need the value in input field,

also the results for that defaulted value.

can be this possible?
