How can Text read from Component GSPRIVNOTE

HI Frds,

I enhance component BT115H_SLSO and in this component we have assignemnt block for Private Notes from component GSPRIVNOTE.

From Zclass, i need to Capture some notes and save it to this assignment block. Here i struck how can i save my note to TEXT attribute (Context note PRIVNOTE ) of component GSPRIVNOTE context note and  read if required.

Also didnt find the relationship with BTadminH with PrivNote.

Thanks
