What causes this issue?

The <ZK>Option Rate Relevant </>indicator is set for more than one
assignment. This is not allowed.
For the system to be able to process input tax distribution for a
document with account assignment to a CO object (order, WBS element,
cost center), the CO object has to be uniquely assigned to one real
estate object. For this real estate object, an option rate method is
entered that is used to determine the option rate that is relevant for
the input tax distribution posting.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

Procedure for System Administrators
