• What is the cause and solution for SAP error message WTADDI_APPL015 - Class &2 for the additional contains plant/customer &1 ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WTADDI_APPL015: Class &2 for the additional contains plant/customer &1
  
  Meaning / Cause:
  This error occurs in the context of Warehouse Management (WM) or Transportation Management (TM) when you try to assign or use a classification (class) for an additional object (such as a plant or customer), but the system detects that the class is already assigned to a different plant or customer.
  
  &1 = Plant or Customer number  
  &2 = Class name
  
  In other words, the class you are trying to assign to a particular plant or customer is already linked to another plant/customer, and the system does not allow this because the class is supposed to be unique or exclusive per plant/customer in this context.
  
  Typical Scenario:
  
  You are maintaining or creating a classification for an additional object (plant/customer) in WM or TM.
  The system checks if the class is already assigned to another plant/customer.
  If yes, it throws this error to prevent duplicate or conflicting assignments.
  
  
  Cause Summary:
  
  The class (&2) is already assigned to a different plant/customer (&1).
  The system expects a one-to-one relationship between the class and the plant/customer in this configuration.
  Attempting to assign the same class to multiple plants/customers violates this rule.
  
  
  Solution / How to Fix:
  
  
  Check existing assignments:
  
  Use transaction CL20N (Change Class) or CL24N (Display Object List) to check which plants/customers are assigned to the class.
  Alternatively, check the configuration tables or master data where the class assignment is maintained.
  
  
  
  Decide on the correct assignment:
  
  If the class should be unique per plant/customer, remove or change the assignment from the other plant/customer.
  If the class needs to be assigned to multiple plants/customers, check if the configuration allows this or if a different class should be created for each plant/customer.
  
  
  
  Adjust the assignment:
  
  Remove the class assignment from the conflicting plant/customer.
  Assign the class to the correct plant/customer as needed.
  
  
  
  If multiple assignments are required:
  
  Consult your functional consultant or SAP documentation to see if the business process or configuration can be adjusted to allow multiple assignments.
  Sometimes, creating separate classes for each plant/customer is the recommended approach.
  
  
  
  
  Related Information:
  
  This error is common in classification-based configuration in SAP WM or TM.
  The classification system in SAP is used to group objects (plants, customers, materials) with certain characteristics.
  The uniqueness of class assignment depends on the business rules and configuration.
  Check OSS notes or SAP Help Portal for specific notes related to your SAP version and module.
  
  
  Example:
  If you try to assign class ZPLANT_CLASS to plant 1000, but this class is already assigned to plant 2000, the system will throw this error.
  
  If you provide the exact transaction or process where this error occurs, I can help you with more precise steps.
