Trigger Supply Function Explicitly

[jitendra_it]

Hello ,

I have a drop down which contains a list of Activities. For Drop down i have used a Supply function to fill values during start of application.

User can add/delete the activities from that drop down.

Now I have to refresh Drop down,  so Can I call Supply Function for that  OR any other way to refresh it

Hi Jitendra,

Yes, you can trigger Supply Function explicitly by using method INVALIDATE( ) of interface if_wd_context_node as below

 METHOD REFRESH.

data lo_node      type ref to if_wd_context_node.

lo_node = wd_context->get_child_node( name = 'MY_NODE' ).

lo_node->invalidate( )

ENDMETHOD.

Hope this helps you.

Hi Soni,

Invalidate the node, to refresh or re-fill the node.

Which drop-down you are using by key or index ??

I don't think you really required supply function to fill data in any drop-down.. And on action of delete/add just repopulate the valueset / itab of drop down.
