How To Fix RS_HCPR_MODEL208 - &1 with non-cumulatives must not be right join partner

SAP Error Message - Details

• Message type: E = Error

• Message class: RS_HCPR_MODEL - Messages related to the HANA Composite Provider Backend

• Message number: 208

• Message text: &1 with non-cumulatives must not be right join partner

What causes this issue?

It is not allowed to join a non-cumulative provider to another provider.
For non-cumulative key figures, the records for a specific time do not
exist in the database directly, but they are computed from the reference
point value and all the deltas records younger than the specified time.
This computation occurs after the execution of the join only on the left
join partner.
If you have modelled an inner join between a non-cumulative provider and
a cumulative provider, then you can resolve this problem by switching
the position (left/right) for the join.

• What is the cause and solution for SAP error message RS_HCPR_MODEL208 - &1 with non-cumulatives must not be right join partner ?

  The SAP error message RS_HCPR_MODEL208 typically occurs in the context of SAP BW (Business Warehouse) when dealing with queries that involve non-cumulative key figures and the use of right joins. This error indicates that there is a problem with the way the data model is set up, particularly when it comes to the relationships between InfoProviders.
  Cause:
  The error arises when a query attempts to use a right join with a non-cumulative key figure. Non-cumulative key figures are those that do not accumulate over time, such as stock levels or balances at a specific point in time. In SAP BW, non-cumulative key figures cannot be used in conjunction with right joins because it can lead to ambiguous or incorrect data interpretations.
  Solution:
  To resolve this error, consider the following steps:
  
  
  Review the Query Design:
  
  Check the query that is generating the error. Look for any right joins that involve non-cumulative key figures.
  If possible, change the join type to a left join or inner join, which are compatible with non-cumulative key figures.
  
  
  
  Adjust the Data Model:
  
  If the right join is necessary for your data model, consider redesigning the model to avoid using non-cumulative key figures in that context.
  You may need to create a new InfoProvider or modify existing ones to ensure that the relationships are appropriate for the type of key figures being used.
  
  
  
  Use Cumulative Key Figures:
  
  If applicable, consider using cumulative key figures instead of non-cumulative ones for the specific query or data model. Cumulative key figures can be used with right joins without causing this error.
  
  
  
  Check for Updates:
  
  Ensure that your SAP BW system is up to date with the latest patches and updates, as there may be fixes or improvements related to query handling.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for more detailed information on handling key figures and joins in BW queries.
  
  
  
  Related Information:
  
  Key Figures: Understand the difference between cumulative and non-cumulative key figures in SAP BW.
  Join Types: Familiarize yourself with different types of joins (inner, left, right) and their implications on data retrieval.
  SAP Notes: Check SAP Notes for any specific guidance or known issues related to this error message.
  
  If the issue persists after trying the above solutions, consider reaching out to your SAP support team or consulting with an SAP BW expert for further assistance.
