• What is the cause and solution for SAP error message CVI_FS_CHECK_CUST_EN031 - Vendor -> BP: Numbers assigned externally with "Same Numbers" only ?

  The SAP error message CVI_FS_CHECK_CUST_EN031 typically occurs during the process of creating or updating Business Partners (BPs) in the SAP system, particularly when dealing with vendor data. This error indicates that there is an issue with the assignment of external numbers for vendors and business partners, specifically when the system is configured to allow only "Same Numbers" for external number assignment.
  Cause:
  The error arises when:
  
  The system is configured to use the same external number for both the vendor and the business partner.
  There is a mismatch or conflict in the external number assignment between the vendor and the business partner.
  The external number for the vendor is not matching the expected format or is already in use by another entity.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Number Assignment Configuration:
  
  Go to the configuration settings for Business Partner and Vendor integration.
  Ensure that the settings for external number assignment are correctly configured to allow "Same Numbers" if that is the intended setup.
  
  
  
  Verify Existing Vendors and BPs:
  
  Check if the external number assigned to the vendor already exists for another business partner or vendor.
  If there is a conflict, you may need to change the external number for either the vendor or the business partner.
  
  
  
  Adjust External Number Assignment:
  
  If you want to allow different numbers for vendors and business partners, you may need to adjust the configuration to allow for different external number assignments.
  
  
  
  Use Transaction Codes:
  
  Use transaction codes like BP (Business Partner) to check the details of the business partner and MK01 (Create Vendor) to check the vendor details.
  Ensure that the external number is unique and follows the required format.
