Not able to enhance context nodes Header and SandardAddress

Hi ,

I have enhaced the component BP_ADDR,enhanced the view StandardAddress.

I can see the enhanced impl class (Implementation Class ZL_BP_ADDR_STANDARDADDRES_IMPL ) and context class (Implementation Class ZL_BP_ADDR_STANDARDADDRES_CTXT ) .

But I am not able to enhance the context nodes Header (Implementation Class CL_BP_ADDR_STANDARDADDRES_CN00 ) and STANDARDADRRESS (Implementation Class CL_BP_ADDR_STANDARDADDRES_CN01 ).

If I right click on these context nodes, there is no option called 'Enhance'.

Please suggest how to enhance these context nodes.

Regards,

Raj.
