Rule Sets in SAP EM

Updated Aug 04, 2023

SAP Event Management (SAP EM) is a powerful tool that allows organizations to manage and process event messages efficiently. A fundamental aspect of SAP EM is the use of "Rule Sets" - a collection of rules that govern the processing and evaluation of event messages for specific event handlers. This article provides an overview of the structure, usage, and integration of rule sets in SAP Event Management.

What are Rule Sets?

A rule set in SAP EM is composed of multiple rules that define how event messages associated with a particular event handler type should be handled. When creating an event handler, SAP EM assigns the relevant rule set to it. Event messages are then processed by SAP EM using the rule set associated with the respective event handler.

Components of a Rule Set

  • Rule Condition: Each rule within a rule set is comprised of a rule condition, which is evaluated during event message processing. If the evaluation of the rule condition returns "TRUE," SAP EM proceeds to execute the rule activity defined for that specific condition.

  • Rule Activity: The rule activity represents the action taken by SAP EM based on the result of the rule condition evaluation. It can be a single-task activity or a multitasking activity. Examples of rule activities include sending an email, executing an event handler method, or calling a function module.

Branching and Rule Set Structure

The rule set operates on a branching mechanism, wherein if the rule condition evaluates to "TRUE," the associated rule activity is triggered. In cases where a value for the condition evaluation is not defined, SAP EM proceeds to execute the next rule in the sequence.

Grouping Rule Conditions

Multiple rule conditions can be grouped together in a set, which can then be called within the rule condition of another rule. This feature allows for complex conditions and enhances the flexibility of the rule set.


SAP EM offers integration capabilities with external systems using Business Application Programming Interfaces (BAPIs) within function modules. By leveraging this functionality, organizations can trigger activities in remote systems. For instance, after a customer completes a proof of delivery, the system can automatically update the delivery document in the application system through the BAPI.

 Benefits of Rule Sets

  • Rule sets allow organizations to customize and fine-tune the behavior of SAP EM based on their specific business requirements.
  • By defining distinct rule sets for different event handler types, SAP EM can react differently to the same event message, providing a highly configurable and adaptable system.


In conclusion, rule sets play a crucial role in SAP Event Management by governing the processing and evaluation of event messages. They consist of rules with associated conditions and activities, offering organizations the flexibility to define their event handling logic. By utilizing rule sets effectively, businesses can streamline their event management processes and enhance automation, resulting in improved efficiency and customer satisfaction.
