• What is the cause and solution for SAP error message RS205 - Only 'E' is allowed as the object type (=single value) ?

  The SAP error message RS205, which states "Only 'E' is allowed as the object type (=single value)," typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when dealing with queries, InfoObjects, or data modeling. This error indicates that the system expects a specific object type, but it has received an invalid or unexpected value.
  Cause:
  The error is usually caused by one of the following issues:
  
  Incorrect Object Type: The query or data model is trying to use an object type that is not allowed. In this case, the system expects the object type to be 'E' (which usually stands for "Characteristic" or "InfoObject"), but it is receiving something else.
  Configuration Issues: There may be a misconfiguration in the InfoProvider or the query definition that leads to the system interpreting the object type incorrectly.
  Data Source Issues: If the data source or the underlying data model has been changed or is not properly defined, it can lead to this error.
  
  Solution:
  To resolve the RS205 error, you can take the following steps:
  
  
  Check Query Definition:
  
  Open the query in the Query Designer and verify that all the objects used in the query are correctly defined and of the expected type.
  Ensure that you are using the correct InfoObjects and that they are set up properly in the system.
  
  
  
  Review InfoObjects:
  
  Go to the InfoObject maintenance transaction (e.g., RSA1) and check the characteristics and key figures being used in the query.
  Make sure that the InfoObjects are active and correctly configured.
  
  
  
  Validate Data Source:
  
  Check the data source associated with the query. Ensure that it is correctly defined and that the data is being loaded properly.
  If there have been recent changes to the data source, consider reactivating it.
  
  
  
  Check for Transport Issues:
  
  If the issue arose after a transport, ensure that all necessary objects were transported correctly and that there are no missing dependencies.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific version of SAP BW/BI you are using, as there may be known issues or patches available.
  
  
  
  Debugging:
