Добрый день.
Насколько я понял
ASSIGN COMPONENT 'FIELD' OF STRUCTURE <S> TO <F>
присваивает <F> значение поля FIELD структуры <S>.

А можно наоборот: заполнить поле 'FIELD' структуры <S> значением из <F>?

Я тоже не очень понял Shocked

Не присваивает значение, а получает указатель на компонент структуры. Поэтому можете присвоить <f> новое значение.

Code:
DATA: BEGIN OF LINE,
        COL1 TYPE I VALUE '11',
        COL2 TYPE I VALUE '22',
        COL3 TYPE I VALUE '33',
      END OF LINE.

FIELD-SYMBOLS: <S>, <FIELD>, <F>.

ASSIGN LINE TO <S>.

ASSIGN COMPONENT 'COL3' OF STRUCTURE <S> TO <F>.
WRITE / <F>.

<F> = '44'.

WRITE / <F>.
