When you try co create a derived mapping configuration while there are model with the higher version is existing in the system, you will receieve an error.
Example: you have following configurations in your system:
Payment model version 8
Payment model version 9
Payment model to destination ISO20022 version 8.12
and you try to create the configuration derived from Payment model to destination ISO20022 version 8.12 mapping configuration, you will receive an error
"Model mapping 'Vendor payment status report' version is not completed".
Workaround: during the derived confugurations design, delete the all parent configurations with higher version or rebase the whole solution to the latest version avaliable.
