  Meaning / 
  Cause:
  This error occurs in the context of SAP Advanced Planning and Optimization (APO), specifically within the Demand Planning or Supply Network Planning modules when working with CIF (Core Interface) or integration scenarios.
  
  The message indicates that a supplementary field (custom or additional field) of a particular structure is not initial (i.e., it contains data) but this field is not supported by the standard CIF or integration process.
  In other words, the system encountered a field that it does not know how to handle because it is not part of the standard data model or the custom field is not properly configured for transfer.
