The APT_TSortOperator warning happens when there is a conflict in the portioning behavior between stages. Usually, because the successor (down Stream) stage has the ‘Partitioning / Collecting’ and ‘Sorting’ property set in a way that conflicts with predecessor (upstream) stage’s properties, which it is set to preserver. This can occur when the successor stage has the “Preserve Partitioning” property set to:
- ‘Default (Propagate)’
- ‘Propagate’, or
- <<Link Name Where Warning Occurred>>: When checking operator: Operator of type “APT_TSortOperator”: will partition despite the preserve-partitioning flag on the data set on input port 0.
- First, if the verify that the partitioning behaviors of both stages are correct
- If so, set the predecessor ‘Preserve Partitioning’ property to “Clear”
- If not, then correct the partitioning behavior of the stage which is in error
