• What is the cause and solution for SAP error message USMD1A005 - Data model &1, ent.tp.&2: Resolved attr. &3 unknown in data persistence ?

  The SAP error message USMD1A005 typically occurs in the context of SAP Master Data Governance (MDG) when there is an issue with the data model configuration or the persistence layer. This error indicates that a resolved attribute in the specified data model and entity type is unknown in the data persistence layer. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  
  Data Model Configuration Issues: The attribute specified in the error message may not be correctly defined in the data model. This could be due to a missing or incorrectly configured attribute in the data model.
  
  
  Persistence Layer Mismatch: The attribute might exist in the data model but not in the underlying database table or persistence layer. This can happen if the data model was changed but the database schema was not updated accordingly.
  
  
  Transport Issues: If the data model was transported from one system to another (e.g., from development to production), there might be inconsistencies between the data model and the database schema.
  
  
  Versioning Issues: If there are multiple versions of the data model, the system might be referencing an outdated version that does not include the specified attribute.
  
  
  Solutions:
  
  
  Check Data Model Configuration:
  
  Go to the data model configuration in the SAP MDG application and verify that the attribute mentioned in the error message is correctly defined.
  Ensure that the attribute is marked as persistent and is included in the relevant entity type.
  
  
  
  Update Database Schema:
  
  If the attribute is missing in the database, you may need to regenerate the database schema for the data model. This can typically be done through the MDG customizing transaction (e.g., MDGIMG).
  Use the transaction MDG_MDS_DATA_MODEL to check and adjust the data model and regenerate the necessary database objects.
  
  
  
  Transport Consistency:
  
  Ensure that all relevant transports have been successfully imported into the target system. Check for any transport errors that might have occurred during the import process.
  
  
  
  Check for Versioning:
  
  Verify that you are working with the correct version of the data model. If there are multiple versions, ensure that the system is referencing the latest version.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the process to identify where the attribute resolution is failing. This may require technical expertise in ABAP and the MDG framework.
