• What is the cause and solution for SAP error message WXP505 - Only two break-downs must be assigned to interface &1 ?

  SAP Error Message:
  WXP505: Only two break-downs must be assigned to interface &1
  
  
  Cause:
  This warning message occurs in SAP when you try to assign more than two break-downs (breakdown characteristics) to a particular interface in the context of Product Costing or Cost Object Controlling (e.g., in the costing sheet or activity type costing). The system restricts the number of break-downs assigned to an interface to a maximum of two.
  The reason behind this restriction is that the interface design or the underlying logic supports only up to two break-downs for proper processing and calculation. Assigning more than two break-downs can lead to inconsistent or unsupported costing results.
  
  Explanation:
  
  Interface &1 refers to the specific interface or costing interface where the break-downs are assigned.
  Break-downs are typically used to split costs or quantities according to certain characteristics (e.g., cost center, activity type, order, etc.).
  The system enforces a maximum of two break-downs to maintain data integrity and calculation
