!!HELP!! F4 Search Help using SAP Web Dynpro

Hi,

I am trying to create a F4 Search Help using SAP Web Dynpro. I have created a BOR object and assigned the BAPI "BAPI_HELPVALUES_GET".

I want to call a elementary Search Help assigned to a field (this field is available on Web Dynpro screen) in the Custom table within SAP using the above BAPI.

What are the next steps to be followed to be able to call the F4 help and what parameters need to be passed through the Web dynpro?

Please advise

Thanks and Rgds
