• What is the cause and solution for SAP error message RS_HCPR_MODEL084 - CompositeProviders not allowed in right join partner ?

  The SAP error message RS_HCPR_MODEL084 indicates that there is an issue with the use of CompositeProviders in a right join partner within a data model in SAP BW/4HANA or SAP BW on HANA. This error typically arises when you attempt to create a right join with a CompositeProvider, which is not supported.
  Cause:
  The primary cause of this error is that CompositeProviders in SAP BW/4HANA do not support being used as the right partner in a right outer join. In a right join, the right table (or partner) is expected to be a DataSource or InfoProvider that can provide the necessary data, but CompositeProviders are designed to be used primarily as a layer for combining data from other InfoProviders.
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Change the Join Type: If possible, change the right join to a left join. This may involve rethinking the data model to ensure that the necessary data is still accessible.
  
  
  Use a Different InfoProvider: Instead of using a CompositeProvider as the right partner, use a different InfoProvider that is compatible with right joins, such as a standard InfoObject, DataStore Object (DSO), or InfoCube.
  
  
  Re-architect the Data Model: If the data model requires a right join, consider restructuring the model to avoid the need for a right join with a CompositeProvider. This may involve creating additional DataStore Objects or InfoProviders that can be used in the join.
  
  
  Check Documentation: Review the SAP documentation for CompositeProviders and join types to ensure that you are following best practices and understand the limitations of the technology.
  
  
  Related Information:
  
  SAP BW/4HANA Documentation: Refer to the official SAP documentation for BW/4HANA for detailed information on CompositeProviders and their limitations.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and what solutions they have implemented.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on working with CompositeProviders.
  
  By following these steps, you should be able to resolve the RS_HCPR_MODEL084 error and successfully implement your data model in SAP BW/4HANA.
