• What is the cause and solution for SAP error message BM807 - External units of measurement cannot be edited here ?

  The SAP error message BM807, which states "External units of measurement cannot be edited here," typically occurs when you are trying to modify a unit of measurement that is defined as an external unit in the system. External units of measurement are usually predefined and are not meant to be changed directly in certain contexts, such as in material master records or during certain transactions.
  Cause:
  
  External Unit of Measurement: The unit of measurement you are trying to edit is defined as an external unit in the system, which means it is linked to a specific standard or external reference.
  Transaction Context: The context in which you are trying to edit the unit of measurement may not allow for changes to external units. For example, certain transactions or screens may restrict editing to ensure data integrity.
  Authorization Issues: You may not have the necessary permissions to edit the unit of measurement in the specific context.
  
  Solution:
  
  Check the Unit of Measurement: Verify if the unit of measurement you are trying to edit is indeed an external unit. You can do this by checking the configuration in the SAP system.
  Use the Correct Transaction: If you need to change the unit of measurement, ensure you are using the appropriate transaction or screen that allows for such changes. For example, you may need to use a different transaction code or access a different part of the material master.
  Consult with a SAP Administrator: If you believe you should have the ability to edit the unit of measurement, consult with your SAP administrator or support team. They can check your user permissions and the configuration settings related to units of measurement.
  Create a Custom Unit: If you need a different unit of measurement, consider creating a new custom unit instead of trying to edit the existing external unit.
  
  Related Information:
  
  SAP Documentation: Refer to the SAP Help Portal or documentation for detailed information on units of measurement and their configuration.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MM02 (Change Material) or MM03 (Display Material) to understand how to navigate the material master.
  User Authorizations: Review your user roles and authorizations to ensure you have the necessary permissions to make changes in the system.
