• What is the cause and solution for SAP error message CH128 - Internal functional location number assignment not allowed ?

  The SAP error message CH128, which states "Internal functional location number assignment not allowed," typically occurs when there is an attempt to assign a functional location number that is not permitted by the system's configuration or business rules. This error is often related to the management of functional locations in the SAP PM (Plant Maintenance) module.
  Causes:
  
  Incorrect Number Range Configuration: The number range for functional locations may not be set up correctly, or the number being assigned falls outside the defined range.
  Internal vs. External Assignment: The system may be configured to only allow external assignment of functional location numbers, and an internal number is being used.
  Status of Functional Location: The functional location may be in a status that does not allow for changes or assignments.
  Authorization Issues: The user may not have the necessary authorizations to perform the assignment.
  System Settings: There may be specific settings in the configuration that restrict the assignment of functional location numbers.
  
  Solutions:
  
  
  Check Number Range Configuration:
  
  Go to transaction code SNRO to check the number range object for functional locations (usually ILOC).
  Ensure that the number range is correctly defined and that the number you are trying to assign falls within the allowed range.
  
  
  
  Review Assignment Method:
  
  Verify if the system is set to allow internal or external assignments. If it is set to external, ensure you are using the correct format for the functional location number.
  
  
  
  Check Functional Location Status:
  
  Use transaction code IL03 to display the functional location and check its status. If it is locked or in a status that does not allow changes, you may need to change its status.
  
  
  
  Authorization Check:
  
  Ensure that the user has the necessary authorizations to create or modify functional locations. This can be checked with the help of your SAP security team.
  
  
  
  Consult Configuration Settings:
  
  If you have access to the configuration settings, check the settings related to functional location management in the IMG (Implementation Guide) under Plant Maintenance > Functional Location > Define Functional Location.
