A list of basic variable mappings is given below *4. DIRECT: a CDM variable is copied directly to a domain variable without any changes other than assigning the CDISC standard label. RENAME: only the variable name and label may change but the contents remain the same. STANDARDIZE: mapping reported values to standard units or standard terminology REFORMAT: the actual value being represented does not change, only the format in which is stored changes, such as converting a SAS date to an ISO8601 format character string. COMBINING: directly combining two or more CDM variables to form a single SDTM variable. SPLITTING: a CDM variable is divided into two or more SDTM variables. DERIVATION: creating a domain variable based on a computation, algorithm, series of logic rules or decoding using one or more CDM variables.
