How To Fix TU406 - Optional contracts incorrectly grouped together in event R964

TU406 - Overview

• Message type: E = Error

• Message class: TU - Billing/Scheduling/Budget Billing

• Message number: 406

• Message text: Optional contracts incorrectly grouped together in event R964

What causes this issue?

In event R964 (creating a pseudo-mandatory group using several optional
contracts),
you selected different optional contracts for which you want to create
a joint budget billing plan.
However, contracts &V1& and &V2& have different portions (&V3&/&V4&).
This means that a joint budget billing plan cannot be created for these
contracts.

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?

Either change the schedule master data for both contracts so that they
contain the same portion, or change event R964 so that you can create
separate budget billing plans for them.
