• What is the cause and solution for SAP error message LOBM_ODATA_MSG028 - Class is not default class for material &1 ?

  The SAP error message LOBM_ODATA_MSG028 with the description "Class is not default class for material &1" typically occurs in the context of OData services when there is an issue with the classification of a material in the SAP system. This error indicates that the material you are trying to access or manipulate does not have a default class assigned to it, which is necessary for certain operations.
  Cause:
  
  Missing Default Class: The material in question does not have a default class assigned in the classification system. In SAP, materials can be classified into different classes, and one of these classes must be marked as the default class for the material to be processed correctly.
  Configuration Issues: There may be configuration issues in the classification system or the OData service that prevent the system from recognizing the default class.
  Data Inconsistencies: There could be inconsistencies in the material master data or classification data that lead to this error.
  
  Solution:
  
  
  Assign a Default Class:
  
  Go to the material master data (transaction code MM02).
  Navigate to the Classification view.
  Check if a default class is assigned. If not, assign a default class to the material.
  Save the changes.
  
  
  
  Check Class Configuration:
  
  Ensure that the class you are trying to assign is correctly configured in the classification system (transaction code CL02).
  Verify that the class is active and has the necessary characteristics defined.
  
  
  
  Review OData Service Configuration:
  
  If you are using a custom OData service, check the service implementation to ensure it correctly handles classification data.
  Ensure that the OData service is properly registered and activated in the SAP Gateway.
  
  
  
  Data Consistency Check:
  
  Run consistency checks on the material master and classification data to identify any discrepancies.
  Use transaction codes like MM03 to view the material data and CL03 to view class data.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to classification and OData services for any specific guidance or known issues.
