By summarizing an aspect, you can reorganize transaction data or combine data from various aspects in a summarization aspect. This allows you to:

• convert transaction data for characteristic values which have been changed (for example, if you have changed characteristic values but the transaction data records have been saved for the old characteristic values)

• transmit transaction data from one aspect to another

Before you can summarize an aspect you must have generated a corresponding program.

If you transfer the data to the same aspect again, you can generate a selection program as well as sender structures and standard transfer rules, for an aspect. If you wish to transfer the data to another aspect, you must update the target aspect and rules in the sender structures.
