  The SAP error message FLBP101, which states "Internal number assignment has been defined for the customer," typically occurs when you are trying to create or manage a customer account in the SAP system, and the system is configured to use internal number assignment for that customer type. This means that the system is set to automatically generate a unique identifier for the customer rather than allowing manual entry.
  Cause:
  
  Configuration Settings: The customer account is set up to use internal number assignment in the configuration settings of the SAP system.
  Manual Entry Attempt: You may be attempting to manually enter a customer number when the system is configured to generate it automatically.
  Incorrect Customer Type: The customer type you are trying to create may not support manual number assignment.
  
  Solution:
  
  
  Use Automatic Number Assignment: If the customer account is set to use internal number assignment, you should not attempt to enter a customer number manually. Instead, leave the customer number field blank, and the system will generate a number for you.
  
  
  Check Configuration: If you need to change the number assignment method:
  
  Go to the configuration settings in SAP (transaction code SPRO).
  Navigate to Financial Accounting (New) > Accounts Receivable and Accounts Payable > Customer Accounts > Master Data > Define Account Groups.
  Check the settings for the relevant account group and see if the number assignment is set to "Internal." If you want to allow manual entry, you may need to change this setting to "External."
  
  
  
  Consult with SAP Administrator: If you are unsure about making changes to the configuration, consult with your SAP administrator or a functional consultant who can assist you in making the necessary adjustments.
