Reason for Modification

Human-readable reason recorded for why an IDV modification was made. The example value "B" indicates this field is likely a coded or abbreviated value rather than free text, so it should be interpreted using the applicable FPDS code set or paired descriptive fields when available.

Use Cases

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

Common Usage

  • Group IDV modifications by stated reason
  • Filter out or isolate specific modification types in trend analysis
  • Support reconciliation of contract changes over time

Common Mistakes

  • Interpreting coded values as free-text reasons
  • Using the field without checking the applicable code meaning or data dictionary for the extract

Query Guidance

Use in WHERE clauses for exact matching on the coded value and in GROUP BY for modification-reason distributions. If the dataset includes a companion description field, join or select both the code and label; otherwise, build a lookup table from observed values before labeling results.
