3 contracts and one rental object solution should be following:
- 2000 / 7 ==> Original (informational) contract has condition type "Basic Rent", and condition purpose of "Statistical" - maybe distinguish it with different contract type
- 2000 / 8 ==> Posting contract has condition type "Basic Rent", with calculation % Share of condition in 2000 / 7, and condition purpose of "Actual Rent"
- 9000 / 2 ==> Posting contract has condition type "Basic Rent", with calculation % Share of condition in 2000 / 7, and condition purpose of "Actual Rent"
Sum of share percent for condition type "Basic Rent" in two last contracts must give 100%.
Remember that with such solution, distribution of revenues to rental objects would be wrong, because all of them will be assigned to rental object in company code 2000. To achieve correct revenues distribution you have to create rental object in each company code.
