Explanation: This error occurs when the retention mapping file (either generic or for a specific vault) contains invalid data. If the file contains too much or too little data or the user defines invalid retention levels in the file, this error occurs.
The retention mapping file is used as follows: in a Vault session when a Vault profile duplication is configured with the Use mappings retention level configured for one of the copies for duplication. The product installs a mapping file template named retention_mappings in install_path/netbackup/db/vault.
To specify a mappings file for any single vault, copy the retention_mappings template to another file and append the name of the vault. For example, netbackup/db/vault/retention_mappings.V1
Recommended Action: Check the entries in the retention_mappings file.
