• What is the cause and solution for SAP error message VJ373 - Internal number assignment is not possible for the material type & ?

  The SAP error message VJ373, which states "Internal number assignment is not possible for the material type &," typically occurs when there is an issue with the configuration of material types in the SAP system. This error is related to the internal number assignment for materials, which is crucial for managing inventory and material master data.
  Cause:
  
  Material Type Configuration: The material type in question may not be configured to allow internal number assignment. This can happen if the material type is set to use external number assignment instead.
  Number Range Issues: The number range assigned to the material type may not be defined or may be exhausted. If the number range is not properly set up, the system cannot assign a new internal number.
  Authorization Issues: There may be authorization issues preventing the creation of materials of that type.
  System Settings: The system settings for number assignment may not be correctly configured, leading to this error.
  
  Solution:
  
  
  Check Material Type Configuration:
  
  Go to the transaction code OMSN (or SPRO -> Logistics General -> Material Master -> Basic Settings -> Material Types).
  Verify the settings for the material type in question. Ensure that it is configured for internal number assignment if that is the desired behavior.
  
  
  
  Review Number Ranges:
  
  Use transaction code SNRO to check the number range object associated with the material type.
  Ensure that the number range is defined and that there are available numbers in the range. If the range is exhausted, you may need to extend it.
  
  
  
  Adjust Number Range Settings:
  
  If necessary, adjust the number range settings to allow for internal number assignment. This can be done in the same area where you checked the material type configuration.
  
  
  
  Check Authorizations:
  
  Ensure that the user has the necessary authorizations to create materials of the specified type. This can be checked with the help of your SAP security team.
  
  
  
  Consult SAP Notes:
