  The SAP error message FMKU065 indicates that you are trying to enter an external document number in a field that is configured to accept only internal document numbers. This typically occurs in the context of financial document processing, such as when dealing with funds management or other financial transactions.
  Cause:
  The error arises because the system is set up to use internal number ranges for certain document types, and you are attempting to input an external document number that does not conform to the expected format or number range. This can happen in scenarios such as:
  
  The document type is configured to use internal numbering.
  The number range settings for the document type do not allow for external document numbers.

  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Document Type Configuration:
  
  Go to the configuration settings for the document type you are working with. This can usually be found in the SAP Customizing Implementation Guide (IMG) under Financial Accounting (FI) or Funds Management (FM).

  Use Internal Document Number:
  
  If the document type is correctly configured to use internal numbering, ensure that you are not entering an external document number. Instead, let the system generate the internal document number automatically.
  
  
  
  Consult with SAP Basis or Functional Team:
  
  If you are unsure about the configuration or how to change it, consult with your SAP Basis or functional team. They can provide guidance on the appropriate settings and any implications of changing number range configurations.
