Hello All,

I want to add one more new button to that toolbar.

I have got sample code which says it will create a function assign it toolbar.

In that code there is reference to interface contrroller and code has to be placed in wddoinit.

I have placed below code in wddoinit of a view it but gives me error

wd_cpuse_alv is unknown or its private or protected. .

Pl can you suggest on this.
