Effect

Defines a data type dtype.

Additions

• (len)
  Determines the length when referring to generic ABAP types.
  
  
• TYPE
  Determines the type by referring to a data type.
  
  
• LIKE
  Determines the type by referring to a data object.
  
  
• [LENGTH len] [DECIMALS dec]
  Determines the length and the number of fractional portions when referring to generic ABAP types.
  
  
• LINE OF
  Reference to the row type of an internal table.
  
  
• REF TO
  Generates a reference type.
  
  
• {[STANDARD] TABLE}|{SORTED TABLE}|{HASHED TABLE}|{ANY TABLE}|{INDEX TABLE}
  Generates a table type for non-generic table types standard, sorted or hashed tables or for the generic table types ANY TABLE or INDEX TABLE.
  
  
• WITH {[UNIQUE|NON-UNIQUE] {KEY comp1 comp2 ...}}|{DEFAULT KEY}
  Defines a unique or non-unique table key. The components of the key are either specified explicitly or are defined by a standard key.
  
  
• INITIAL SIZE n
  Defines the initial memory usage of an internal table.
  
  
• RANGE OF
  Defines a ranges table with the row type of a selection table.
