access Variables of attributes TAB in WDComponent

Hi All,

Can anyone explain how to access Variables of attributes TAB of component controller and view .

1)I have declared variable

g_werks1 in component controller attributes tab 

g_werks2 in view  attributes tab .

can I use g_werks1 and g_werks2 any where in my compoent.

2)can we change the content of the g_werks1 and g_werks2 ?.

Please provide me some example how use them.

I gave a try as below

in component controller methods

g_werks1 = '123'.

in view methods

WD_COMP_CONTROLLER->g_werks1 = '123'.

g_werks2 = '123' w.r.t View

its throwing error “Field "G_WERKS" is unknown. It is neither in one of the specified tables nor defined by a "DATA" statement."

Thanks
