A declaration expression with the declaration operator
FIELD-SYMBOL declares a
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.
- 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.

- 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
- 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.
