Role &1 of partner &4 is only valid in period &2

What causes this issue?

The validity of role &V1& is restricted for this business partner to the
period &V2&. However, the object to which the business partner is to be
assigned is valid for a longer period (validity period of object: &V3&).

System Response

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

How to fix this error?

Extend the validity period of the role to cover period &V3& in business
partner processing or assign a different partner to the object for the
period in which role &V1& is not assigned to the partner.
