Documentation

Definition

Indicates that preceding, required expected events must be reported prior to the current expected event. That is, the events should occur in a logical sequence, for example, arrival before departure.

Use

If you want to work with prior requirements, you must carry out the following:

  1. Set the Predecessor Required indicator.
  2. Define a rule to carry out the rule activity method ARE_PRIOR_REQS_MET (Have Prior Required Expected Events Been Reported for an Event?). For more information, see the Implementation Guide for Event Management -> General Settings in SAP Event Management -> Functions, Conditions, and Activities in SAP Event Management -> Define Activities for SAP Event Management.
  3. Use the defined rule within a rule set to react to required expected events. For more information, see the Implementation Guide for Event Management -> Reactions to Event Messages -> Define Rule Sets.
