The Data Vault Loader job may not always convert datatypes automatically. The Data Vault Loader job may not be able to find a generic datatype to convert when it creates objects in Data Vault. Or, the Data Vault Loader job may have conversion errors or warnings when it loads numeric data to Data Vault. In either case, you must convert the datatypes manually.
Convert the datatypes if you receive one of the following errors in the log file:
Unsupported Datatype Error
If the Data Vault Loader job processes an unsupported datatype and is not able to identify a generic datatype, you receive an error message in the log file. The log file indicates the unsupported datatype, the table and column the datatype is included in, and the metadata xml file location that requires the change.
Conversion Error
If the Data Vault Loader job loads columns that have large numeric data or long strings of multibyte characters, it generates conversion warnings in the log file. The log file indicates the reason why the job failed if there is a problem converting data.
