Rules and Guidelines for Windowing Configuration

Rules and Guidelines for Windowing Configuration

Certain guidelines apply when you configure a transformation for windowing.
Consider the following rules and guidelines when you define windowing properties for a window function:
  • When you configure a frame, the start offset must be less than or equal to the end offset. Otherwise, the frame is not valid.
  • Configure a frame specification if you use an aggregate function as a window function. LEAD and LAG operate based on the offset value and ignore the frame specification.
  • You cannot use complex ports as partition or order keys.
  • Assign unique port names to partition and order keys to avoid run-time errors.
  • The partition and order keys cannot use both a dynamic port and one or more generated ports of the same dynamic port. You must select either the dynamic port or the generated ports.
