• What is the cause and solution for SAP error message LOP037 - Number range &1 is for external numbers only. Use an internal interval ?

  The SAP error message LOP037 indicates that you are trying to use an external number range for a document or transaction that is expected to use an internal number range. This typically occurs in scenarios where the system is configured to expect internal number assignment but an external number is being provided.
  Cause:
  
  Number Range Configuration: The number range for the document type you are trying to create or process is set to "external" in the configuration, but the system is expecting an "internal" number.
  Document Type Settings: The document type you are using may be configured to use internal number assignment, but you are attempting to enter an external number.
  User Input Error: The user may have mistakenly entered a number when the system is set to automatically generate one.
  
  Solution:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects).
  Find the relevant number range object associated with the document type you are working with.
  Verify if the number range is set to "external" or "internal". If it is set to "external", you may need to switch to an internal number range if that is what your process requires.
  
  
  
  Change Document Type Settings:
  
  If you are using a specific document type, check its configuration in the relevant customizing transaction (e.g., for sales documents, use VOTXN).
  Ensure that the document type is set to use the correct number range type (internal or external) based on your business requirements.
  
  
  
  Use Internal Number Assignment:
  
  If the system is configured to use internal number assignment, do not enter a number manually. Leave the number field blank, and the system will generate a number automatically.
  
  
  
  Consult with SAP Basis or Functional Consultant:
  
  If you are unsure about the configuration or how to change it, consult with your SAP Basis or functional consultant to ensure that the settings align with your business processes.
