You are not in the logical system for master data maintenance

What causes this issue?

In ALE Customizing, you defined system &V3& for controlling area &V1&
as the logical system for master data maintenance (in Cost Center
Accounting). However, you are currently working in logical system &V2&.

How to fix this error?

You can only maintain the required data in logical system &V3&, and
distribute it from that system to the decentralized system.

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