Mandatory fields validation in webdynpro abap

Hi Experts,

I would like to validate mandatory fields.If we did not enter any data, fields should get highlited and should show appropriate message.

for example ,check the below screenshot.

Here batch or meterial or plant are mandatory fields. these field are highlighted and shown a message using

'cl_wd_dynamic_tool=>check_mandatory_attr_on_view'.  Highlited is fine. but i need an appropriate message as well.

How would i achive both functionalities (ie. highlighted and appropriate message)

Best regards,

Narasimha.
