  The SAP error message RSDME254 indicates that there is a compatibility issue with an InfoObject in your data model. Specifically, it states that the InfoObject you are trying to use is not compatible with the model key because it has a compound InfoObject associated with it.
  Cause:
  
  Compound InfoObject: The InfoObject in question is a compound InfoObject, which means it is made up of multiple characteristics. This can lead to compatibility issues when trying to use it in certain contexts, such as in queries or data models that expect a single characteristic.
  Model Key Mismatch: The model key you are trying to use does not align with the structure of the compound InfoObject. This can happen if the InfoObject is being used in a way that does not support its compound nature.
  
  Solution:
  
  Check the InfoObject Definition: Review the definition of the InfoObject to confirm that it is indeed a compound InfoObject. You can do this by navigating to the InfoObject in the SAP BW modeling tools.
  Use the Right InfoObject: If you need to use a single characteristic instead of a compound InfoObject, consider using the individual characteristics that make up the compound InfoObject.
  Adjust the Data Model: If your data model requires the use of the compound InfoObject, ensure that all components of the model are compatible with it. This may involve adjusting the model key or the way the InfoObject is being utilized.
  Check Query Design: If this error occurs in the context of a query, ensure that the query is designed to handle compound InfoObjects correctly. You may need to adjust the query to use the individual components of the compound InfoObject.
  Consult Documentation: Refer to SAP documentation or help resources for more detailed guidance on working with compound InfoObjects and their compatibility with data models.
