Business Condition: Attribute Value Comparison

The 'Attribute Value Comparison' operation allows users to compare an attribute value on a selected object in relation to whatever the business condition is testing, be it a constant value or another attribute value on the same object. Alphanumeric comparison is used in most cases, except for dates (date, ISO date, and ISO date and time) and numbers.

For example, consider an attribute named ‘Active’ on products which has value ‘Yes’ and ‘No.' If the value is ‘Yes,’ then they are active products, and they should be approved. If value is ‘No,’ then consider the objects as non-active products and do not approve them.

Another example would be classifying products based on the product attribute ‘Color.' If the value of the ‘Color’ attribute is ‘Red,’ then classify the products into ‘Red’ classifications. However, if the value of the ‘Color’ attribute is ‘Blue,’ then classify the products into ‘Blue’ classification.

Special Comparisons

• Numeric comparison is used when both values are number based (fractions, integers, or numbers).
• When numerical values are compared with units, the system attempts to convert the values to base units.
• Multivalued attributes and attributes of the validation base type Embedded Number are not supported.
