  The SAP error message /SAPAPO/MC01001 Characteristic & already exists typically occurs in the context of SAP Advanced Planning and Optimization (APO) when you are trying to create or modify a characteristic that already exists in the system. This error indicates that the characteristic you are attempting to define or use is already defined in the system, which leads to a conflict.
  Cause:
  
  Duplicate Characteristic: The most common cause of this error is that the characteristic you are trying to create or modify already exists in the system.
