Creates an import mapping file for use in MRI data migration.
An import mapping file specifies mappings between columns of exposure data in account, location, and reinsurance resource files and the corresponding database columns in the EDM.
During an MRI Import job, exposure data stored in the accounts resource file, locations resource file, and reinsurance resource file are imported into the EDM based on the mappings specified in the import mapping file.
