Copied sales orders types

Dear Gurus,

I work on SAP SD support roles now. I joined SAP support project. I work as SAP SD Consultant.

There is a case. Standart sales order type is OR and rush order type is SO in standart sap system.

I copied OR sales order type to Z1 and I copied SO sales order type to Z2. And I customized all things the same for Z1 and Z2 sales order types related to sales order types, item category and schedule lines. I guess Z1 and Z2 will behave the same. Or example automatically create outbound delivery for Z1 and Z2 sales order types. But They dont behave the same. Z1 and Z2 sales order types behaves differently.

I can not debug very well. My abap knowledge is limited. So I can not understand why Z1 and Z2 order types behaves differently. Why do Z1 and Z2 behave differently? I customized all things the same for Z1 and Z2 sales order types related to sales order type, item category and schedule line.

I wonder standart sales order codes controls some things that I can not see these things in customizing( sales order type, item category, schedule line, copy control customizings)

Maybe it is related to SAP Architecture. I read a lot of documents about sap sd but I didnt find answer for this question If you help me, I will so be happy.

Thank you for your answers
