Rules
Last modified: August 20, 2024
Introduction
A rule is a special kind of microflow. Its result should be an enumeration or a Boolean and it can be used in a decision to make a decision based on that result. The idea is that complicated decisions can be consolidated in rules and reused in various places.
Differences from Microflows
Rules are very similar to microflows; see the documentation on Microflows for more information on how to build a rule. There are only a few differences between rules and microflows:
- A rule can only be used in a decision
- The return type has to be Boolean or enumeration
- A rule cannot change data in the database; the actions to create, delete, change and rollback objects are not available in rules
- A rule cannot interact with the client; the actions to show or close forms, show messages, send validation feedback and download files are not available in rules
- A rule cannot call web services, generate documents or import XML
These differences mean that rules perform better than microflows if you don’t need any of the additional features which microflows provide.
