Add assignment block

Hello,

I am new in CRM framework. I have a requirement to do .

In Sales Contract ( BT121H_SLSC ) we do have a assignment block called Authorized partner which is getting value from parties involve Sold to party partner function ,

Same assignment block we need to insert in Sales Quotation  (BT115QH_SLSQ)  with same functionality which is to copy sold to party as authorized sold to party.

Thanks
