Suppose that for a number of different interfaces/mappings the same translation has to be done.
e.g. BUKRS A1 -> 0001
BUKRS A2 -> 0002
BUKRS B1 -> 0100
Is there some way to define the translation logic on a central place in stead of in every mapping where this translation has to be performed? The reason is easy maintenance when the translation has to change or extended.
