• What is the cause and solution for SAP error message RSDF_GENERATOR018 - Classify one characteristic only as the primary characteristic ?

  The SAP error message RSDF_GENERATOR018 indicates that when you are trying to create or modify a DataSource in SAP BW (Business Warehouse), you have not specified a primary characteristic for the classification of the data. This is a common issue when working with DataSources that require a clear definition of how data should be categorized.
  Cause:
  The primary cause of this error is that the system requires at least one characteristic to be designated as the primary characteristic for the DataSource. This characteristic is essential for the classification of the data being extracted and loaded into the BW system. Without a primary characteristic, the system cannot determine how to organize or interpret the data.
  Solution:
  To resolve this error, you need to follow these steps:
  
  
  Access the DataSource Definition: Go to the DataSource definition in the SAP BW system where you encountered the error.
  
  
  Identify Characteristics: Review the list of characteristics associated with the DataSource. You need to ensure that at least one characteristic is marked as the primary characteristic.
  
  
  Set Primary Characteristic:
  
  In the DataSource definition, look for an option to classify or set characteristics.
  Select one characteristic that you want to designate as the primary characteristic.
  Mark it as the primary characteristic (this is usually done by checking a box or selecting an option in the interface).
  
  
  
  Save Changes: After designating the primary characteristic, save your changes to the DataSource.
  
  
  Re-test the DataSource: After making the changes, try to execute the DataSource again to ensure that the error has been resolved.
  
  
  Related Information:
  
  DataSource: In SAP BW, a DataSource is a structure that defines how data is extracted from a source system. It includes the fields and characteristics that will be used in the BW system.
  Characteristics: These are attributes or fields that describe the data. In BW, characteristics are used to classify and analyze data.
  Primary Characteristic: This is the main attribute that will be used for grouping or categorizing the data in reports and analyses. It is crucial for ensuring that data is organized correctly in the BW system.
  
  If you continue to experience issues after following these steps, it may be helpful to consult SAP documentation or reach out to your SAP support team for further assistance.
