Calling a BAPI in Webdynpro which takes no parameter

[konchada_saikrishna]

Hi all,

I am new to WebDynpro, I am trying to implement data access to R/3 with a BAPI. The bapi takes no imports, it consists of a method(Zbapicon) which retrieves the table data, the table data is to be displayed dynamically. And how to change the properties of UI element programmatically (example setting a field readonly, making it mandatory etc). Please post the solution, the appropriate solution is rewarded

Hi Konchada,

To set field as read only/mandatory..U can DECLARE

A component CONTEXT ELEMENT and u have to bind that context variable into corresponding property of that Ui Element.[ex: Cretate Context called STATE and datatype as THE TYPE OF UI-ELEMENT STATE property and bind this with that coresponding field's STATE Property ]and write ur code such a way to change the context value..

ThankYou,

Regards,

Ramganesh.
