ABAP has one rule for converting structures that do not contain internal tables and do not contain strings as components. There are no conversion rules for structures that contain internal tables or strings. You can only make assignments between structures that are compatible.
You can combine convertible structures in the following combinations:
· Converting a structure into a non-compatible structure
· Converting elementary fields into structures
· Converting structures into elementary fields
In each case, the system first converts all the structures concerned to type c fields and then performs the conversion between the two resulting elementary fields. The length of type c fields is the sum of the lengths of the components. This rule applies to all operations using structures that do not contain internal tables.
If a structure is aligned, the filler fields are also added to the length of the type C field.
