How To Fix CNV_CMIS_U_20066 - BC Set information already exists in central system

CNV_CMIS_U_20066 - Overview

• Message type: E = Error

• Message class: CNV_CMIS_U_20 - CMIS Upg: Messages from XPRA functions

• Message number: 066

• Message text: BC Set information already exists in central system

What causes this issue?

One step within the BC Set activation is to determine the active BC Sets
in the receiver system and store it temporarily in the central system.
The program determined that there already exists some BC Set information
in the central system which could mean that a parallel project is
ongoing.

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?

Check if there is a parallel project (CMIS or any other migration
project with an integrated upgrade) in process. If yes, you must ensure
that the BC Set activation is executed one after the other. The
information of the BC Sets is only stored once in the central system.
If you are sure that you are the only project that is going to
subsequently activate the BC Sets, you can use the troubleshooting
functionality, assigned to this activity, to initialize the BC Set
information in the central system at first. After the initialization,
you can start the activation of the BC Sets again.
