Hi Vijay,

Web Dynpro provides two types of pre-implemented search helps :

1. ABAP Dictionary Search help

2. OVS

[Input help for WDA|http://help.sap.com/saphelp_nw04s/helpdata/en/b3/4d3642eca5033be10000000a1550b0/frameset.htm]

I have created a blog on implementing OVS help in WDA. You can refer that for sample code.

[OVS|]

In addition, you can also provide help through Drop Downs and Select options.

[Working with Select Options|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/c09fec07-0dab-2a10-dbbe-c9a26bdff03e]

Hope it will help.

Thanks.

Actually there are three. There is also Freely Programmed Value Help:

Hi Vijay,

As u have just started in WD ABAP.

I think u shud go wid using the Dictionary help option in the context of that attribute.

You would be knowing the standard help for that data element whose name u can give in the field asking for search help name in attribute properties

I hope it helps.

Hi Vijay,

For Search Help , we need to specify the attribute's property

( Input Help Mode as Dictionary Search Help or automatic ) , but in this case that attribute's data type should have search help.

One more option is OVS(Object Value Selector), In this case we need to Reuse Standard Component WDR_OVS into our component.

Thanks and Regards,

Vijay
