45 pages, 19 figures, uses epsfig.sty, (axodraw.sty included) To appear in the Review Volume ``Heavy Flavours II'', eds. A.J. Buras and M. Lindner, Advanced Series on Directions in High Energy Physics, World Scientific Publishing Co., Singapore. Revision made on November 19, 1997 amounts to including "note added" concerning bounds on delta_LR from charginos, and a few correlated minor changes. Misprint in eq. (A.5) corrected

We consider Flavour Changing Neutral Current processes in the framework of the supersymmetric extension of the Standard Model. FCNC constraints on the structure of sfermion mass matrices are reviewed. Furthermore, we analyze supersymmetric contributions to FCNC transitions which remain in the limit of flavour-conserving sfermion mass matrices. Implications of the FCNC constraints on the structure of sfermion mass matrices for SUSY breaking and sfermion mass generation are discussed. We conclude that the supersymmetric flavour problem is intriguing but perhaps not as severe as it is commonly believed.
