Scenario	Tips
You want to modify the columns of a decision table referenced in an expression set version.	If the expression set version is active, deactivate it. Deactivate the decision table. Update the decision table columns to add, delete, or change the data types. Save and activate the decision table. Refresh the expression set version to synch the changes made in the decision table. Utilize the new decision table variables in subsequent steps and fix any errors that appear. Save and activate the expression set version.
You want to delete a decision table referenced in expression set versions.	If a decision table is referenced in any expression set version, you can’t delete it. First, deactivate, and delete the decision table reference in each expression set version that it’s referenced in. Fix any errors that appear in the expression set version steps and save. After the decision table reference is removed from all expression set versions, deactivate the decision table. Now, delete the decision table.
A decision table is referenced in an expression set version. The usage type of the decision table is now modified.	The expression set version step throws an error. Ensure that the usage type of the decision table and expression set match.
The source object permissions or the source object fields used in the decision table are modified.	The decision table is no longer valid. Recreate the decision table with the updated source object configuration.
