Valid Value Fields
Valid values are selective codes required for certain fields (e.g., MATRIX, LABCODE, and PARLABEL, etc.). Specific values for these fields standardize data entry, ensure data consistency, and prevent errors. Freely entered data might contain extra spaces, commas, or dashes; making meaningful data manipulation or data searches more difficult.
