internal table, it is regarded as a component name, otherwise is is regarded as a component number.
The corresponding component of the structured field struc is assigned to the field symbol <fs>.
Return Value
- SY-SUBRC = 0:

Before Release 6.10, assigning structure components to field symbols was the only way of accessing components
of formal parameters or field symbols if these were typed unstructured. Since Release 6.10, you can
also specify componenents of unstructured typed field symbols and formal parameters. when specifying a data object dynamically.

C VALUE 'c',
D VALUE 'd',
END OF STR,
CN(5) VALUE 'D'.
