hi,

Use the statemnt

DESCRIBE FIELD

Use the edition TYPE typ [COMPONENTS com]

More help use F1

example fropm F1 help

DATA: BEGIN OF struc1,

comp1 TYPE c LENGTH 1,

comp2 TYPE string,

BEGIN OF struc2,

comp1 TYPE c LENGTH 1,

comp2 TYPE i,

END OF struc2,

END OF struc1,

typ1 TYPE c LENGTH 1,

comp1 TYPE i,

typ2 TYPE c LENGTH 1,

comp2 TYPE i.

DESCRIBE FIELD: struc1 TYPE typ1 COMPONENTS comp1,

struc1-struc2 TYPE typ2 COMPONENTS comp2.

hiiii

to get field you can use

DATA: FIELD0(8) TYPE N, 
           FIELD1. 
DESCRIBE FIELD FIELD0 TYPE FIELD1.
Result: FIELD0 contains the value 'N'. 

you can also use following FM

DDIF_FIELDINFO_GET.
