Decision service limitations (deprecated)

When you are creating or modifying rules using the rule editor, the following limitations apply:

• You cannot create complex rules that use decision tables and Business Action Language (BAL) rules in a single rule component.
• You cannot write rules that include behaviors (methods).
• The rule editor does not support rules that include data with complex (many-to-many) relationships.
• The rule editor does not support the following business objects (variable types):
  • SQLResult
  • XMLDocument
  • XMLElement
  • XMLNodeList

The following types of rule components are not supported, or are supported with some limitations:

• Decisions that require complex algorithms such as chaining, Rete, or stateful execution are not supported; only sequential execution is supported.
• Decisions that reference runtime process instance data cannot be exported for use in IBM® Operational Decision Manager.
• Multi-channel decisions are not supported.
• Decisions that use methods, custom verbalization and model abstraction are not supported.
