2 options to tell aggregator input data is already sorted

1. If the sources are relational ,make sure that number of sorted ports are given in Source qualifier.
2. Include the Sorter transformation before sending the data to Aggregator.

If any of these 2 options are not included but sorted input option is enabled in Aggregator transformation then session fails.
