SAS Intelligent Decisioning 5.4 runs on SAS Viya 3.5. New features and enhancements enable you to do the following:

• add Equals, Range, and LIKE multi-branch nodes to a decision. With Equals and LIKE branches, you can also combine branch paths using the OR operator.
• enable performance logging for decisions that are run on the Micro Analytic Score service by setting the includeLoggingInGeneratedCode configuration property.
• trace how variable values change as a decision executes. The Enable value tracing option for decision tests enables you to capture the values of decision variables as they change while the decision executes.
• use a subdecision to score the rows in a data grid. The Score rows in this data grid option is available when you are mapping variables for a subdecision. 
• copy and paste the content of specific versions of decisions, rule sets, lookup tables, treatments, and treatment groups.
• delete specific versions of decisions, rule sets, and lookup tables.
• control whether published rule sets and decisions use updated versions of lookup tables without republishing rule sets or decisions. The lookupStaticBinding configuration option enables you to specify whether published content uses new versions of lookup tables.
• update the version of a rule set or subdecision that is used in a decision.
• generate PDF documentation for decisions, rule sets, lookup tables, and treatment groups. For decisions, you can choose to include the decision diagram and the code for custom code nodes. You can also choose to download additional documents for any rule sets, treatment groups, and subdecisions used in the decision.
• view, edit, and manage custom code files from the Code Files category view.
• use custom code files to submit SQL queries to a Google BigQuery database.
• build custom SQL query files in SAS Studio.
• validate SQL and DS2 code files.
• edit the description of code file nodes in a decision.
• add data quality functions to rule expressions.
• copy rules between rule sets.
• duplicate variables in a rule set or decision.
• duplicate treatment attributes.
• add treatment attributes from another treatment.
