Very dynamic field-symbols
In a SAP customer function you sometimes want to refer to data from
the calling program (if this data is not part of the function interface).
A function group has its own global data area.
Using the following syntax for field-symbols it is possible to do just this.
=> calling program is SAPMV45A
=> Field we want to refer to is YVBAK-BSTNK
This same logic also works for external subroutines but of course not for SUBMIT.
Code: FIELDNAME =
ASSIGN (FIELDNAME) TO .
