SOLD_NAME with CL_CRM_UIU_BTPARTNERSET_CN

Hi Experts

I need to read the SOLD_NAME attribute value from the context node BTPARTNERSET. and based on SOLD_NAME I have to write code in BTADMINH's Attributes Get method to satisfy requirement.

SOLD_NAME attributes get method does not have BOL relation code. It has logic related to methods available in CL_CRM_UIU_BTPARTNERSET_CN

when i tried to use conventional approach to e to get the  entity of context node BTPARTNERSET I am unable to get the attribute,

i am only getting crm_guid which is under context node BTPARTNERSET With attribute name STRUCT.CRM_GUID.

please tell me how can i read this context node attribute ?

Thanks
