• What is the cause and solution for SAP error message FLBP021 - Number range for account group &1 has not been defined externally ?

  The SAP error message FLBP021 indicates that there is an issue with the number range assignment for a specific account group in the Financial Accounting (FI) module. This error typically occurs when you attempt to create or manage a financial document, and the system cannot find a defined number range for the specified account group.
  Cause:
  The error is caused by the absence of an externally defined number range for the specified account group. In SAP, number ranges are used to uniquely identify documents, and if a number range is not defined for a particular account group, the system will not be able to generate a new document number.
  Solution:
  To resolve the FLBP021 error, you need to define an external number range for the specified account group. Here are the steps to do this:
  
  
  Access the Number Range Configuration:
  
  Go to the SAP Easy Access screen.
  Navigate to the following path: 
  SPRO -> SAP Reference IMG -> Financial Accounting (New) -> Financial Accounting Global Settings (New) -> Document -> Document Number Ranges -> Define Document Number Ranges
  
  
  
  
  Select the Appropriate Area:
  
  Choose the relevant area for which you want to define the number range (e.g., General Ledger, Accounts Payable, Accounts Receivable).
  
  
  
  Define the Number Range:
  
  In the number range intervals, check if the number range for the specified account group exists.
  If it does not exist, create a new number range interval by specifying the following:
  
  Number Range Interval: Define the range (e.g., 100000 to 199999).
  External/ Internal: Specify whether the number range is external (user-defined) or internal (system-generated).
  Account Group: Assign the number range to the relevant account group.
  
  
  
  
  
  Save Your Changes:
  
  After defining the number range, save your changes.
  
  
  
  Test the Configuration:
  
  Try to create or manage the financial document again to see if the error persists.
  
  
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like OBAS (for defining number ranges) or OBA7 (for number range intervals) to access the configuration directly.
  Authorization: Ensure that you have the necessary authorization to make changes to number range configurations.
  Documentation: Refer to SAP Help documentation for more detailed information on number range management and configuration.
  
  By following these steps, you should be able to resolve the FLBP021 error and successfully manage your financial documents in SAP.
