FIELD-SYMBOL - Inline Declaration

Other versions: 7.31 | 7.40 | 7.54


... FIELD-SYMBOL(<fs>) ...


A declaration expression with the declaration operator FIELD-SYMBOL declares a field symbol <fs> to which a memory area is assigned in the current operand position. The declared field symbol is visible statically in the program from the location FIELD-SYMBOL(<fs>) and is valid in the current context. The declaration is made when the program is compiled, regardless of whether the statement is actually executed.

The declaration operator FIELD-SYMBOL can be specified in every valid declaration position (this involves assignments of the memory area only). The typing of the field symbol is determined using the statically known type of the assigned memory area. It can be generic and complete.

A field symbol <fs> declared inline cannot be used in a reading position of the same statement.

Programming Guideline

Only use inline declarations locally.


  • A valid statement with an inline declaration of a field symbol can generally be interpreted as a short form for a declaration statement used as a direct prefix.
... <fs> ...
Exceptions to this rule occur only if an identically named field symbol from a more global context is used in the same statement. This data object is still valid in the statement and is only obscured after the statement.

  • Just like the statement FIELD-SYMBOLS, an inline declaration does not open a local context for the current statement block. An inline declaration for a field symbol can only be made once within a context and the field symbol cannot yet be declared there using FIELD-SYMBOLS.

  • If the type of the assigned memory area is defined by reference to a data type in ABAP Dictionary, it is used together with its semantic attributes, such as field help, input help, or conversion routines.


Inline declaration of a field symbol for an internal table in an ASSIGN statement and inline declaration of a field symbol for the rows of the table in a LOOP.

DATA(dref) = NEW t_itab( ( 1 ) ( 2 ) ( 3 ) ). 

ASSIGN dref->* TO FIELD-SYMBOL(<itab>).
