Effect

Declares a variable or an instance attribute var.

Additions

• TYPE
  Defines the type through reference to a data type.
  
  
• LIKE
  Defines the type through reference to a data object.
  
  
• [LENGTH len] [DECIMALS dec]
  Defines the length and the number of decimal places in relation to generically inbuilt ABAP types.
  
  
• LINE OF
  Defines the type through reference to the row type of an internal table.
  
  
• REF TO
  Creates a reference variable.
  
  
• {[STANDARD] TABLE}|{SORTED TABLE}|{HASHED TABLE}
  Creates a standard, sorted, or hash 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 explicitly specified or defined by a standard key.
  
  
• INITIAL SIZE n
  Defines the initial memory usage of an internal table.
  
  
• WITH HEADER LINE
  Obsolet: Defines a header line of the same name for an internal table.
  
  
• RANGE OF
  Defines a ranges table with the row type of a selection table.
  
  
• VALUE { val | {IS INITIAL} }
  Defines a start value of the data object as val or the initial value.
  
  
• READ-ONLY
