• What is the cause and solution for SAP error message AH907 - Enter a consecutive number ?

  The SAP error message AH907 "Enter a consecutive number" typically occurs in the context of document numbering, particularly when dealing with document types that require sequential numbering. This error indicates that the system expects a number that follows a specific sequence, but the number entered does not meet that requirement.
  Cause:
  
  Non-Consecutive Numbering: The number you are trying to enter does not follow the expected sequence. For example, if the last used number was 1001, and you try to enter 1003 without having used 1002, the system will throw this error.
  Number Range Configuration: The number range for the document type may not be properly configured, or it may have gaps that are not allowed.
  Manual Entry: If you are manually entering document numbers, it is easy to skip a number or enter a number that is not in the allowed range.
  
  Solution:
  
  Check the Last Used Number: Verify the last used number for the document type you are working with. You can do this by checking the number range settings in the SAP configuration.
  Use the Next Number: Instead of entering a number manually, allow the system to generate the next available number automatically. This can often be done by leaving the number field blank or using a specific function to generate the next number.
  Review Number Range Configuration: Go to the transaction code SNRO (Number Range Objects) and check the configuration for the relevant number range object. Ensure that the number ranges are set up correctly and that there are no gaps.
  Consult with SAP Basis or Configuration Team: If you are unsure about the configuration or if the issue persists, it may be necessary to consult with your SAP Basis or configuration team to ensure that everything is set up correctly.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like SNRO for number range objects or SNUM for number range management.
  Documentation: Refer to SAP Help documentation for more details on number range management and error handling.
  User Permissions: Ensure that you have the necessary permissions to create or modify documents in the system, as this can sometimes affect the ability to enter numbers correctly.
  
  By following these steps, you should be able to resolve the AH907 error and continue with your work in SAP.
