• What is the cause and solution for SAP error message GK841 - External number assignment not allowed in automatic postings ?

  The SAP error message GK841, which states "External number assignment not allowed in automatic postings," typically occurs when there is an attempt to use an external number range for document postings in a context where only internal number assignment is permitted. This can happen in various financial transactions, such as journal entries or automatic postings in the General Ledger.
  Cause:
  
  Number Range Configuration: The number range for the document type being used is set to internal, but the system is trying to assign an external number.
  Document Type Settings: The document type configuration may not allow external number assignment for automatic postings.
  Posting Configuration: The configuration for the specific posting area (like automatic postings in Financial Accounting) may not support external number assignment.
  
  Solution:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects).
  Find the relevant number range object for the document type you are using.
  Ensure that the number range is set up correctly, and if you need external number assignment, make sure that the number range is configured to allow it.
  
  
  
  Review Document Type Settings:
  
  Use transaction code OBY6 to check the settings for the document type.
  Ensure that the document type is configured to allow external number assignment if that is your requirement.
  
  
  
  Adjust Posting Configuration:
  
  If you are using automatic postings, check the configuration in SPRO (SAP Reference IMG).
  Navigate to Financial Accounting (New) > General Ledger Accounting > Business Transactions > Automatic Postings.
  Review the settings to ensure they align with your number assignment requirements.
  
  
  
  Use Internal Number Assignment:
  
  If external number assignment is not necessary, consider using internal number assignment for the document type in question.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP Basis or functional consultant for specific configurations related to your system.

  Transaction Codes: SNRO (Number Range Objects), OBY6 (Document Type Configuration), SPRO (SAP Reference IMG).
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional guidance.
  User Authorization: Ensure that the user has the necessary authorizations to perform the postings and access the configuration settings.
