User Created SUMMARY Delta Rowset

In addition to the system created Delta rowsets created by the DELTACRE function, you can create additional Delta rowsets based on the combination of existing Delta rowsets into a new rowset known as a DELTA SUMMARY rowset. Keywords are provided to allow you to select the Delta rowsets that will be included for summarization. During the summary function, special data handling is performed according to the following:

• Beginning date and time information is taken from the earliest rowset processed.
• Ending date and time information is taken from the oldest rowset processed.
• The duration column is the sum of the duration of the selected rowsets.
• Counter columns are added together (summarized).
• Non-counter columns are set to the value of the oldest (ending) rowset.
