For each audience included in a flowchart or Optimize session that uses strategic segments, you map the segment membership system table to a physical table that defines segment members. For example, to use the default Customer audience in an optimization session that includes strategic segments, you must map the audience system table Customer Segment Membership to the UA_SegMembership segment database table. You populate the database table using the Create Seg process.

Using strategic segments in Campaign flowcharts or Optimize sessions is optional. If you map the segment membership table, each time you run the flowchart or Optimize session, Campaign or Optimize updates the table. This is unnecessary processing overhead if you are not using strategic segments.
