Does Detector or Subsystem Analyzer record who touched a Table during a time frame?
z/OS 1.13 and up.
A keyed User ID and End User ID, SQL Text enabled Standard Activity collection contains information for tables that are Selected/Deleted from, Inserted into, or Updated. Although these are summary statements that don't contain the exact time that the access occurred, they can tell you all DML occurrences.
If the SQL access exceeded PDT's Exception Threshold or created an SQL Error, it's access time is also captured by User ID.
Regarding Subsystem Analyzer, you can trace Table activity backwards until you reach the SQL statements in Detector. Unfortunately, the User ID isn't displayed
