A ranges table type is a special case of a table type. A ranges table type describes the structure of an internal table for administering complex areas, i.e. the type of an internal ranges table in the ABAP program.

Ranges tables can be used for example in logical conditions (IN operators) in the SELECT, IF, WHILE and CHECK statements or to pass data to selection tables.

The row type of a ranges table type has a fixed structure. The row type consists of the 4 components SIGN (sign), OPTION (comparison operator), LOW (lower limit) and HIGH (upper limit) in this order.

The type of components LOW and HIGH is defined by an elementary associated type. It can be defined by specifying a data element or by directly defining the data type, number of places and if necessary the number of decimal places.

A ranges table type always has Standard table access mode and a standard key that is non-unique.
