Unit of Work processing
A Unit of Work (UOW) is all records associated with either a particular subject or a particular subject visit. Tables with a UOW processing type must have either the subject or subject and visit columns marked as SDTM identifiers and the UOW Processing Type must be set to either Subject or Subject and Visit.
UOW processing reads all source records and notes the UOW key—the value of the subject or subject and visit columns—for each record, and adds the UOW key to an execution set—the set of subjects or subject visits to be processed. The system then processes only records for the units of work represented in the execution set and no records for other units.
Target tables defined for Unit of Work processing also accept Reload processing.
See Table 8-7.
