Documentation

For table types, the following keys are allowed:

  • Key components
    Components of the line type are specified explicitly as key components (explicit key specification).
  • Line Type
    The line type of the table is used as key. This definition makes sense, particularly for tables without a structure, since no key components can be defined for them. Access to the table row of a table without a structure is possible in the ABAP program with the pseudo component TABLE_LINE.
  • Standard key
    The structure of the key depends on the category of the row type. For a structured row type, the standard key consists of all the character-like components of the table row. In an elementary row type or reference type as row type, the standard key consists of the entire table row. The standard key is empty for a table type as row type.
    Remember that an empty key is only allowed for the Standard Table access type.
  • Not specified
    With this setting, it is possibleto define a generic table type.
