An input rule for a dynamic struct determines the schema of the struct. You can define the input rules based on the name or type of the struct element in an upstream transformation.
Specify which elements to include or exclude in a struct based on the element names or data type. You can define multiple rules. The Data Integration Service applies rules in the order in which they appear in the input rules list. Include all ports is the default input rule. Create at least one include input rule for a dynamic struct port.
You cannot use input rules to rename elements of a struct port.
