ABENPRIMARY_TABLE_KEY_GLOSRY - PRIMARY TABLE KEY GLOSRY

primary table key

Each internal table has a primary table key that is either a self-defined key or the standard key. In hashed tables, the primary key is a hash key and in sorted tables, the primary key is a sorted key. Both table types are key tables for which key access is optimized, and the primary key thus has its own administration. The key fields of these tables are write-protected when individual lines are accessed. Standard tables also have a primary key, but the corresponding access is not optimized, there is no separate key administration, and the key fields are not write-protected.
