Hi ,

for webdynpro abap u can create a super class say .. Z_GLOBAL inheriting the CL_WD_COMPONENT_ASSISTANCE . declare the public constant in that ...then for every component's assistance class inherit this global class so that u can use the constants .

Goto your class in se24. In the "Attributes" tab of the class, declare the constants. When you create a class attribute, you should specify the type as Instance or Static. You can specify the attribute as a constant there.

in the class go to the tab "attributes" declare the attribute and its level as constant visibility as public and then at the last tab i.e initial value give the value to the attribute .

hi Prosun,

if you declare an assistance class,then you can access it through the instance <b>wd_assist</b> like wd_this and wd_comp_controller.

for example,if the constant named 'Const' is declared in the attribute of the assitant class,then you can call it as <b>wd_assist->const</b> from any where of the component.

i think it will solve your problem.

subhasis.

reward points if useful.

class_name->attribute name .. say class name Z_Global .. attr name abc then

Z_GLOBAL=>abc or wd_assist->abc
