  To resolve the FLBP102 error, you can take the following steps:
  
  
  Provide an External Number: When creating or modifying a customer account, ensure that you provide a valid external customer number. This number should not conflict with existing customer numbers in the system.
  
  
  Check Configuration: If you believe that external number assignment should not be enforced, you can check the configuration settings in the SAP system:
  
  Go to the transaction code SPRO (SAP Project Reference Object).
  Navigate to Financial Accounting (New) > Accounts Receivable and Accounts Payable > Customer Accounts > Master Data > Define Account Groups.

  Consult Documentation: Review the SAP documentation or help files related to customer master data creation to ensure you are following the correct procedures.
  
  
  User Authorization: Ensure that you have the necessary authorizations to create or modify customer accounts in the system.
