&1 has no real estate assignment that is relevant for input tax dist.

What causes this issue?

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.
For &V1&, there is no real estate assignment that is relevant for input
tax distribution during the time period from &V2& to &V3&.

How to fix this error?

Possible reasons are:
Reason:
&V1& is not assigned to a real estate object during the relevant time
period.
Solution:
Assign the CO object to a real estate object.
Reason:
Multiple assignment is allowed for the CO object in Customizing, and
&V1& is assigned to multiple real estate objects in the relevant time
period.
Solution:
Designate one of these assignments as the one that is applicable for the
input tax distribution (<ZK>Relevant to Option Rate</> indicator in the
master data of the real estate object).

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