  The SAP error message /SCMB/LSO103 Error during optimization typically occurs in the context of SAP Advanced Planning and Optimization (APO) or Supply Chain Management (SCM) when there is an issue during the optimization process of a supply chain model. This error can arise due to various reasons, including data inconsistencies, configuration issues, or problems with the optimization algorithm itself.
  Possible Causes:
  
  Data Inconsistencies: Missing or incorrect data in the master data (e.g., product, location, or resource data) can lead to optimization errors.
  Configuration Issues: Incorrect settings in the optimization profile or planning area can cause the optimization process to fail.
  Resource Constraints: If the optimization process encounters constraints that cannot be satisfied, it may trigger this error.
