Hi Senol Cagri,
I appriciate your efforts ( trying all possible ways ) before writing to Scn.
But condition splitting is possiable with in between the Business partners, where as the contract belongs to one company code (In this case Revenue / expenses will flow to that company code only) which may not solve your purpose.
Its better to create two different RE Contracts for each company code, according to your company requirements and maintain the conditions & unit prices accordingly which will be more convinient to track the same in future, as we cant add two company codes in a RE contract.
