Effect

Declares a variable or a var instance attribute.

Additions

• (len)
  Defines the length with reference to generic predefined ABAP types.
  
  
• 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 with reference to generically predefined ABAP types.
  
  
• LINE OF
  Defines the type through reference to the row type of an internal table.
  
  
• BOXED
  Declares a structure as a static box.
  
  
• REF TO
  Generates a reference variable.
  
  
• {[STANDARD] TABLE}|{SORTED TABLE}|{HASHED TABLE}
  Generates a standard,sorted, orhashed table.
  
  
• WITH {[UNIQUE|NON-UNIQUE]{KEY [primary_key [ALIAS key_name] COMPONENTS] comp1 comp2 ...}}|{DEFAULT KEY}
  Defines aunique or non-unique primary table key called primary_key. The components of the key are either specified explicitly or defined by astandard key. ALIAS can be used to define an alias name (key_name).
  
  
• WITH EMPTY KEY
  Defined an empty primary table key.
  
  
• WITH {UNIQUE HASHED}|{{UNIQUE|NON-UNIQUE} SORTED} KEY key_name COMPONENTS comp1 comp2 ...
  Defines a secondary table key called key_name. Administration is performed using either a unique hash algorithm, a unique sorted secondary index, or a non-unique sorted secondary index.
  
  
• INITIAL SIZE n
  Defines the initial memory usage of an internal table.
  
  
• WITH HEADER LINE
  Obsolete: Defines a header line of the same name for an internal table.
  
  
• RANGE OF
  Defines a ranges table with the row type of aselection table.
  
  
• VALUE { val | {IS INITIAL} }
  Defines the start value of the data object as val or the initial value.
  
  
• READ-ONLY
  Does not protect private attributes from write accesses outside of their own class.
  
  
• READER|WRITER|LOCATOR|{LOB HANDLE} FOR ... COLUMNS ...
  Derives a lob handlestructure from the structure of a database table.
