First you define the structure to be transferred. In this example, it is a field string, but it could also be a
help field, the header liner of an internal table or an ABAP/4 Dictionary work area.
The field string can also be transferred from an include report.
Next, you fill the structure. In principle, all statements that perform a value assignment can be used
here. Examples include MOVE, COMPUTE, MOVE-CORRESPONDING, MOVE TO and WRITE
TO. Refer also to the relevant online documentation.
Finally, you transfer the structure with the TRANSFER statement.
