Accurately define data sources

• Recommendation: Make sure to define data sources and associate them with the correct vendor.

• Rationale: Defining data sources for file-watched data, and assigning the correct vendor to the files they provided improves DMW's filtering functionality discrepancy handling.

• Additional information: You can select discrepancies with a common data source, and select Send to Spreadsheet to produce a file that lists the discrepancies for a single vendor. Properly defining data sources for input data models prevents cross-contamination of data issues from different vendors and the manual effort that is required to distribute discrepancies to the correct recipients.
