Add a Table Rule

A table rule in a decision service or flow project is a shorthand way of defining multiple field rules.

To add a table rule:

1. In the rule editor, on a new line, click the menu button in the margin.
2. In the drop-down menu, select Table.
   
   
   
3. In the rule block, a table rule template is added. This table has one condition column and one result column by default.
   
   
   
   Note: An error will be shown for the rule until "result" is replaced with a result field. Also, a warning will be shown for the result field in the Tasks list for the project until the field is used.
4. Provide values for the column headings and cells as required.
   
   
   
   Tip: For further information and examples on using table rules, see Write Rules Using Tables.

Note that a table rule must have:

• one or more condition columns. Condition columns can be either condition field columns or condition expression columns.
  • A condition field column has the name of the condition field as the heading, and constants or comparisons for the column cells. For example:
    
    
  • A condition expression column has a blank heading, and complete expressions in the column cells. For example:
    
    
    
• one or more result columns. A result column has the name of the result field as the column heading. For example:
  
  
• one or more condition rows.
• valid values in the cells:
  • for String fields, values must be in quotes. For example, "high".
  • for Number fields, the dollar sign can optionally be included before currency values. For example, $535.60.
  • for Date fields, values must be in the format yyyy-mm-dd. For example, 1952-06-30.
  • for Boolean fields, values must be either TRUE, true, FALSE or false.
  • blank values are acceptable

Note: If none of the conditions in a table are met, then a "null" value will be the result.
