WN461 - Details

• The SAP error message WN461 indicates that there is an existing Business Partner (BP) that is already assigned as a supplier, and the system is prompting you to maintain the customer data for that Business Partner. This typically occurs in scenarios where you are trying to create or modify a Business Partner that has conflicting roles (e.g., both customer and supplier) in the system.
  
  Cause:
  
  Existing Business Partner: The Business Partner you are trying to create or modify already exists in the system with a supplier role.
  Role Assignment Conflict: The system requires that a Business Partner can have multiple roles (like customer and supplier), but there may be a conflict in how these roles are assigned or maintained.
  Data Inconsistency: There may be inconsistencies in the data related to the Business Partner that need to be resolved.
  
  
  Solution:
  
  Check Existing Business Partner: Use transaction code BP to check the details of the existing Business Partner.
