Background documentation Cost Determination Locate the document in its SAP Library structure

The system determines the cost of every possible search strategy.

This is necessary for the following reasons:

·        There can be several search strategies, of which the best must be determined

·        There are cases where searching with the help of an index would be more costly than a sequential search.

The costs relate to the expected number of I/O processes that would have to be executed due to the chosen search strategy.

These costs are also the result of the EXPLAIN statement.
