For account determination values, Classic RE differentiates among thesecontract types: lease-out, management contract, andReal Estate general contract. In RE-FX, the system uses the sameaccount determination values for all three contract types.
You have to take further action in the following case: you use conditiontypes that are allowed for more than one of these contract types, andyou want the system to differentiate the account determination for thesecondition types using the account determination values. In that case,you have to define different account determination values in RE-FX, andchange the account determination value of the contracts after themigration, either manually, or automatically using your own user-definedreport.
