Background documentation Area Condition Locate the document in its SAP Library structure

Area conditions are search conditions with a comparison predicate or a BETWEEN predicate, to which the following prerequisites apply:

Only area conditions that satisfy these prerequisites can use the Optimizer to determine an optimal search strategy.

Whether the area is defined using a BETWEEN operator or using a combination of the relational operators <= and => is irrelevant to the search strategy.

Conditions in the format ...NOT (<column_spec> < < | <= | => | > > <extended_value_spec>) or. ...NOT (<column_spec> NOT BETWEEN <extended_value_spec> AND <extended_value_spec>)are, where possible, converted to an expression without NOT, with a correspondingly negated operator. The system then continues processing the condition in this converted format.
