Schema with ISA

 Hi,

Does biztalk 2006 r2 comes with a schema that have ISA and GS nodes? Or Do I need to create my won schema which inclode ISA, GS and ST level?  All the schema under x12 directory have ST level and below.

I want to receive 850 from partner, with “preserverd interchange”,  in orchestration then I need to get ISA and GS level info and store them in DB. I think if i have a schema with ISA and GS level then I can use it as message type in orchestration’s receive shame. Then i can access all the value that came through.

If i create this kind of schema, will it cause any isse in EDI Receive port at disassampling time?
