  The SAP error message CCMM457 indicates that there is a discrepancy in the quantity of a structure gap in a production or planning context. This message typically arises in the context of capacity planning or production order management, particularly when dealing with capacity requirements and available capacities in a manufacturing environment.
  Cause:
  The error message CCMM457 is triggered when the system detects that the quantity of a structure gap (which could refer to a production order, a planned order, or a similar entity) has been decreased. The specific components of the message are:
  
  &1: The identifier of the structure gap (e.g., a production order number).
  &2: The amount by which the quantity has been decreased.
  &3: Additional information that may provide context (e.g., the reason for the decrease).
  
  This situation can occur due to various reasons, such as:
  
  Changes in production planning or scheduling.
  Manual adjustments made by users to production orders or planned orders.
