Other way to invoke F4 search help

[siongchao_ng]

Hi all,

To have search help on my input fields in the web dynpro screen, I create a structure and input the search help name in the structure. Then I bind my input field to my structure field and I will have the search help working.

Problem: The client system do not have SAP dictionary data types. It will not have search help name as well. Any other way for me to have search help for my input fields?

Hi Chao

Search helps in WDA, if search help is available at dictionary level, no need to create any search help, you get automatically.

If you want to create search help for any input field, another option is using OVS. we have WDR_OVS component for search helps, you need to reuse this component in your custom component, just change some coding according to your requirements you get search help.

Go through these documentation and helps...

Hi kissnas,

I am using this link you gave:

freely programmed inputhelp

http://wiki.sdn.sap.com/wiki/display/WDABAP/Freelyprogrammedinput+help

I created the a search help component z_search_help. Now I embed it in my used component list of my main component z_read_infotype. Then in my properties tab of my view, i use "create controller usage" to embed my z_search_help interface controller.

Problem: In the View controller's context, I create a node and later an attribute. I can;t find my controller usage for my attribute. It has no values. How? My embeddding has gone wrong?

Hi siong ,

Where have you created the attribute?If it is in component controller , make sure you have created the component usuage in component controller also.

Thanks,

Aditya.

Hi Aditya,

I am creating in my view controller.

Since there is not values in the component dropdown, I tried to enter manually the name of my search help component and it return this error below:

"COMP_ADDRESS_TYPE is not component usage of an implementation of IWD_VALUE_HELP."

What did I missed in my embedding?

Hi ,

I guess you have missed the implementation of the interface IWD_VALUE_HELP in the provider interface.

Have a look at the document.It elaborates freely programmed search help.

Hi Chao,

Create your context in component controller and do mapping. Create controller usgaes properly in view controller and component controller too..

Thanks,
