sorted key
Unique or non-unique table key of an internal table, in which the assignment to the table rows is administrated using a table index, the key entries of which are sorted into ascending order. A sorted key is the primary table key of a sorted table and can be assigned to all internal tables as a secondary table key. During access to an internal table using a sorted key, the response time is logarithmically connected to the number of table entries, as the access takes place using a binary search.
