We have introduced new validations to set limits to number columns relative to other number columns. If an entered value meets a limit condition, the configured error message will be displayed. This capability is available for data groups in all contexts.
Further we've introduced the 'Current Product' source for Logic Engine conditions configured Trigger Conditions or Conditional Values. This source allows conditional behaviors to be driven based on product requirements in the product the datagroup is linked to.
