  The SAP error message /SAPAPO/RRP857 Order quantity cannot be changed typically occurs in the context of SAP Advanced Planning and Optimization (APO) when a user attempts to modify the order quantity of a planned order or a production order that is not allowed to be changed. This can happen for several reasons, and understanding the cause is essential for finding a solution.
  Causes:
  
  
  Order Status: The order may be in a status that does not allow changes. For example, if the order is already confirmed or has been released for production, changes to the order quantity may be restricted.
  
  
  Planning Parameters: Certain planning parameters or settings in the APO system may restrict changes to order quantities. This can include settings related to the planning strategy or the order type.
  
  
  Dependencies: There may be dependencies or constraints in the planning process that prevent changes to the order quantity. For example, if the order is linked to a specific production schedule or resource availability.
  
  
  User Authorizations: The user may not have the necessary authorizations to change the order quantity. This can be due to role-based access controls in the SAP system.
  
  
  Integration Issues: If the order is integrated with other systems (like SAP ERP), there may be synchronization issues that prevent changes from being made.
