SORTDUP=PHYSICAL | LOGICAL

Syntax Description

PHYSICAL
removes duplicates based on all the variables that are present in the data set. This is the default.

LOGICAL
removes duplicates based on only the variables remaining after the DROP= and KEEP= data set options are processed.

Interactions:
The SORTDUP option is relevant only when DROP= or KEEP= data set options are specified on the input data set for the SORT procedure. The NODUP option is a SORT procedure option that removes duplicate records. For further information about how NODUP and SORTDUP interact, see the SAS Procedures Guide.
