Description
Timestamp showing when the FPDS Other Transaction Award record was last updated in the source system. It reflects the most recent modification to the transaction detail, not necessarily the award date or the date the procurement action occurred.
Business Meaning

Use Cases

  • Dictionary lookup and field explanation
  • SQL filtering and grouping
  • Analytical reporting and reusable query building

Common Usage

  • Incremental data loads and refresh logic
  • Identifying amended or corrected award records
  • Filtering records by reporting or update window

Common Mistakes

  • Using it as the award date or transaction date
  • Comparing it as a plain string without datetime conversion

Query Guidance

Convert the string to a timestamp/datetime type before filtering or sorting. Use it in WHERE clauses for update windows, in window functions to keep the latest version of a record, and in GROUP BY only after truncating to the desired time grain.
