Use Cases

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

Common Usage

  • Classifying modification types in award history analysis
  • Grouping contracts by change reason for trend reporting
  • Filtering records to specific modification categories

Common Mistakes

  • Assuming the value is a full-text explanation rather than a code
  • Comparing coded values across datasets without confirming the local code definition

Query Guidance

Use this field as a filter or GROUP BY dimension only after confirming the codebook or paired description for the specific dataset extract. In SQL, preserve the raw value for joins and aggregation, and if available, alias it to a decoded label in a reference table or CASE expression.
