RSOBI_MF163 - Details

• The SAP error message RSOBI_MF163 indicates that a DataSource does not have any key fields defined. This can occur in the context of SAP BW (Business Warehouse) when you are trying to create or use a DataSource that lacks the necessary key fields for data extraction or reporting.
  
  Cause:
  
  Missing Key Fields: The DataSource you are trying to use does not have any key fields defined. Key fields are essential for uniquely identifying records in the DataSource.
  Incorrect Configuration: The DataSource may not have been configured correctly during its creation or modification.
  DataSource Type: Some types of DataSources inherently require key fields, and if they are not defined, this error will occur.
  
  
  Solution:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource in the SAP BW system (transaction code RSA1).
  Check the definition of the DataSource to ensure that key fields are defined.
  If key fields are missing, you will need to add them.
