Specifically, it states that the InfoObject "&1" is compounded, which means it is part of a compound key. This can lead to issues when trying to use it as a unique key in data mining scenarios.
  Cause:

  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Compounded InfoObject: Check the definition of the InfoObject in the SAP BW system to confirm that it is indeed compounded with other InfoObjects.
  
  
  Use a Non-Compounded InfoObject: If possible, use a non-compounded InfoObject as the unique key for your data mining model. You may need to create a new InfoObject that is not compounded if none exists.
  
  
  Modify the Data Mining Key: If you need to use the compounded InfoObject, consider modifying your data mining key to include all the components of the compounded InfoObject. This way, you can create a unique key that consists of all the necessary parts.
  
  
  Check Data Mining Configuration: Review the configuration of your data mining model to ensure that it aligns with the requirements for unique keys. Make adjustments as necessary.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more detailed guidance on handling compounded InfoObjects in data mining scenarios.
  
  
  Related Information:
