ABAP Code Snippet

What does it do? Defines a data type dtype.

ABAP Addition (len)
Defines the length when referring to generic predefined ABAP types.
TYPE
Defines the type by referring to a data type.
LIKE
Defines the type by referring to a data object.
[LENGTH len] [DECIMALS dec]
Defines the length and number of fractional portions when referring to generic predefined 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}|{ • TABLE}
Generates a table type for the non-generic table categories standard, sorted, or hashed tables or for the generic table categories ANY TABLE or • TABLE.
WITH {[UNIQUE|NON-UNIQUE] {KEY [primary_key [ALIAS key_name] COMPONENTS] comp1 comp2 ...}}|{DEFAULT KEY}
Defines a unique or non-unique primary table key primary_key. The components of the key are either specified explicitly or are defined by a standard key. You can use ALIAS to define an alias name key_name.
WITH EMPTY KEY
Defines an empty primary table key.
WITH {UNIQUE HASHED}|{{UNIQUE|NON-UNIQUE} SORTED} KEY key_name COMPONENTS comp1 comp2 ...
Defines a secondary table key key_name. It is managed using either a unique hashed algorithm, a unique sorted secondary index, or a non-unique sorted secondary index.
{WITH|WITHOUT} FURTHER SECONDARY KEYS
Defines the generic property of the table type with respect to the secondary table key.
INITIAL SIZE n
Defines the initial memory usage of an internal table.
RANGE OF
Derives a ranges table with the row type of a selection table.
READER|WRITER|LOCATOR|{LOB HANDLE} FOR ... COLUMNS ...
Derives an LOB handle structure from the structure of a database table.
