Last Modified: November 7, 2019

Specify how a Data Preprocessor instance reacts to data changes in the raw data area.

  1. In Data Preparation, click Data Preprocessor Instances.
  2. Select an instance and click »Manage»Processing Rules.
  3. Specify whether the Data Preprocessor instance processes changed files and reacts to deleted files. The Data Preprocessor instance always processes new files in the raw data area automatically.
  4. Specify how the Data Preprocessor instance handles the files that are already in the processed data area when the associated raw data changes.
    Processed Data Description
    Replace existing files Overwrites the existing files in the processed data area with the new processed files. Deleted files in the raw data area are also deleted in the processed data area.
    Rename existing files Adds an underscore and a sequential number to the names of the old files in the processed data area, and saves the new processed files under the original name in the processed data area. The file with the lowest sequential number is therefore always the latest version of a processed file. You cannot combine this setting with the React to deleted files setting.
    Save under a new, unambiguous filename Saves the new processed files in the processed data area under the original name with an underscore and a sequential number. The file with the highest sequential number is therefore always the latest version of a processed file. You cannot combine this setting with the React to deleted files setting.
    Flag processing as error Saves the new processed files in the processed data area under the original name, and assigns the name Error, extended by an underscore and a sequential number, to the original files in the process data area. You cannot combine this setting with the Process changed files setting.
