  The SAP error message RMSL150, which states "Technical key &1: External key cannot be determined," typically occurs in the context of SAP Retail or SAP S/4HANA when the system is unable to map an external key (like a product ID or material number) to its corresponding technical key in the database. This can happen for various reasons, including data inconsistencies, missing master data, or configuration issues.
  Causes:
  
  Missing Master Data: The external key you are trying to use may not exist in the system. This could be due to missing material master records or other related data.

  Authorization Check: Ensure that the user has the necessary authorizations to access the data associated with the external key. You can check this in the user roles and authorizations.
