• What is the cause and solution for SAP error message CVI_FS_CHECK_CUST_EN022 - Customer -> BP: Numbers assigned externally with "Same Numbers" only ?

  The SAP error message CVI_FS_CHECK_CUST_EN022 typically occurs in the context of the Customer-Vendor Integration (CVI) process when there is an issue with the assignment of external numbers for Business Partners (BPs) in the system. This error indicates that the system has detected a conflict with the external number assignment for customers and business partners, specifically when the same external number is being used for multiple entities.
  Cause:
  The error is caused by the following scenarios:
  
  Duplicate External Numbers: The same external number is assigned to multiple business partners or customers, which violates the uniqueness requirement for external identifiers in the system.
  Configuration Issues: The settings in the system may not be correctly configured to handle external number assignments, leading to conflicts.
  Data Migration Issues: If data was migrated from another system, it may have resulted in duplicate external numbers being assigned to different business partners.
  
  Solution:
  To resolve the CVI_FS_CHECK_CUST_EN022 error, you can take the following steps:
  
  
  Identify Duplicates:
  
  Use transaction codes like BP (Business Partner) or SE16N to check the Business Partner master data for duplicate external numbers.
  Query the relevant tables (e.g., BUT000 for Business Partner data) to find any duplicates.
  
  
  
  Correct External Number Assignments:
  
  If duplicates are found, you will need to either change the external number of one of the conflicting business partners or customers to ensure uniqueness.
  You can do this by editing the Business Partner master data in the BP transaction.
  
  
  
  Review Configuration:
  
  Check the configuration settings for Business Partner and Customer integration in the SAP system. Ensure that the settings for external number assignment are correctly defined.
  Navigate to the relevant customizing settings in SPRO (SAP Project Reference Object) to review the configuration.
  
  
  
  Data Migration Review:
