• What is the cause and solution for SAP error message EB188 - Document numbers are assigened internally for document type &1 (&2) ?

  The SAP error message EB188 indicates that document numbers are assigned internally for a specific document type. This typically occurs in the context of document management or financial transactions where the system is set to generate document numbers automatically rather than allowing users to input them manually.
  Cause:
  
  Document Type Configuration: The document type specified in the error message is configured to use internal number assignment. This means that the system generates the document number automatically based on predefined rules.
  User Input: A user may be attempting to enter a document number manually for a document type that is set to use internal numbering, which is not allowed.
  System Settings: The configuration settings in the SAP system for the specific document type may not allow for external number assignment.
  
  Solution:
  
  Use Internal Number Assignment: If you are trying to create a document of the specified type, you should allow the system to generate the document number automatically. Do not attempt to enter a document number manually.
  Check Document Type Configuration: If you believe that the document type should allow for manual entry, you can check the configuration settings in the SAP system:
  
  Go to the transaction code SPRO (SAP Reference IMG).
  Navigate to the relevant section for document types (e.g., Financial Accounting, Controlling, etc.).
  Review the settings for the specific document type to see if it is set to internal number assignment.
  
  
  Change Document Type Settings: If necessary and if you have the appropriate authorization, you can change the document type settings to allow for external number assignment. However, this should be done with caution and typically requires consultation with your SAP administrator or functional consultant.
  Consult Documentation: Refer to SAP documentation or help resources for more detailed information on document types and number assignment.
  
  Related Information:

  SAP Notes: Check SAP Notes for any known issues or updates related to document number assignment.
  User Authorization: Ensure that you have the necessary authorizations to create or modify documents in the system.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a functional consultant who can provide more tailored assistance based on your specific SAP environment and configuration.
