You can use the ASSIGN COMPONENT OF STRUCTURE statement.

An example please?

An F1 help on the keyword will be helpful.

You will need to have a DO loop inside which you will have to use the ASSIGN COMPONENT statement.

i = 1.

DO.

   ASSIGN COMPONENT i OF ls_struc TO <field_value>.

   IF <field_value> IS NOT ASSIGNED.

        EXIT.

   ENDIF.

   i = i + 1.

ENDDO.

If you want the structure's field names as well, then you can get them using FM DDIF_NAMETAB_GET. And, in that case, instead of using the counter i, you can use the field name in the ASSIGN COMPONENT statement.

You may also use the name of a field instead of it's component index.

TYPES:

  BEGIN OF struct,

       field1 TYPE c,

          field2 TYPE c,

End of struct

.

DATA:

     ls_struct TYPE struct

     .

ASSIGN COMPONENT 'FIELD1'

  OF STRUCTURE ls_struct

     TO <fs> .

That will allow you to access the fields by name. You may also use a variable in place of a literal string; so you could use variables to store the names of the fields you want to access.
