• What is the cause and solution for SAP error message MDG_DT_DATA_MODEL087 - Enter a valid relation for relationship for deriving hierarchy attributes ?

  The SAP error message MDG_DT_DATA_MODEL087 typically occurs in the context of Master Data Governance (MDG) when there is an issue with the relationships defined for deriving hierarchy attributes in a data model. This error indicates that the system expects a valid relationship to be defined, but it is either missing or incorrectly configured.
  Cause:
  
  Missing Relationship: The relationship that is supposed to derive hierarchy attributes is not defined in the data model.
  Incorrect Configuration: The relationship may be incorrectly configured, leading to the system being unable to derive the necessary attributes.
  Data Model Issues: There may be issues with the data model itself, such as missing or incorrect definitions for the hierarchy attributes.
  Inconsistent Data: The data being processed may not conform to the expected structure or relationships defined in the data model.
  
  Solution:
  
  
  Check Data Model Configuration:
  
  Go to the MDG data model configuration and verify that the relationships are correctly defined.
  Ensure that the hierarchy attributes are properly linked to the relevant entities.
  
  
  
  Define Missing Relationships:
  
  If a relationship is missing, define it in the data model. This can typically be done in the MDG customizing settings.
  Ensure that the relationship type is appropriate for the hierarchy attributes you are trying to derive.
  
  
  
  Validate Hierarchy Attributes:
  
  Check the hierarchy attributes to ensure they are correctly set up and that they reference the correct entities and relationships.
  Make sure that the attributes are marked as derivable if they are supposed to be derived from relationships.
  
  
  
  Data Consistency Check:
  
  Run consistency checks on the data to ensure that there are no inconsistencies that could be causing the error.
  Validate the data being processed to ensure it adheres to the expected structure.
  
  
  
  Consult Documentation:
