• What is the cause and solution for SAP error message FB664 - Customer & not created, account group & has internal number assignment ?

  The SAP error message FB664 indicates that a customer cannot be created because the specified account group has internal number assignment. This means that the system is set up to automatically generate customer numbers for the specified account group, and the user is trying to manually assign a customer number, which is not allowed.
  Cause:
  
  Internal Number Assignment: The account group you are trying to use for the customer has been configured to use internal number assignment. This means that the system will automatically generate a customer number when a new customer is created.
  Manual Number Assignment Attempt: If you attempt to manually enter a customer number while creating a customer in an account group that uses internal number assignment, the system will throw this error.
  
  Solution:
  
  Allow the System to Generate the Number: When creating a new customer, do not enter a customer number. Leave the customer number field blank, and the system will automatically generate a number for you.
  Change Account Group Settings: If you need to manually assign customer numbers, you can change the configuration of the account group to allow for external number assignment. This can be done in the SAP configuration settings (transaction code OBD2). However, this change should be made with caution and typically requires authorization and a thorough understanding of the implications.
  Check User Permissions: Ensure that you have the necessary permissions to create customers in the specified account group.
