• Message class: RS2HANA_VIEW - HANA Views for BW Objects

• Message number: 170

• Message text: &1:BW hierarchy not valid for ext. HANA view. Query view not generated.

Possible reasons for this error:
1. The hierarchy view for the characteristic does not exist on HDB.
Reactivate the characteristic with the proper HANA Model flags or go to
transaction rs2hana_admin and repair the HANA objects for the
characteristic.
2. The BW hierarchy activated for a characteristic in Query Designer is
not valid for consumption via the hierarchy view. This can be
checked/repaired via transaction RSRV, elementary test
"Hierarchies/Check individual hierarchy: BW Hierarchy in SAP HANA".

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message RS2HANA_VIEW170 - &1:BW hierarchy not valid for ext. HANA view. Query view not generated. ?

  The SAP error message RS2HANA_VIEW170 indicates that there is an issue with a BW hierarchy that is not valid for an external HANA view. This typically occurs when you are trying to create or generate a HANA view from a BW query that includes a hierarchy that is not supported or properly configured for use in HANA.
  Causes:
  
  Invalid Hierarchy Configuration: The hierarchy used in the BW query may not be correctly defined or may not be compatible with HANA views.
  Unsupported Hierarchy Types: Certain types of hierarchies (e.g., non-standard hierarchies) may not be supported in HANA views.
  Missing Hierarchy Data: The hierarchy might not have the necessary data or structure to be utilized in the HANA view.
  Incompatibility with HANA: The BW query may include characteristics or structures that are not compatible with HANA.
  
  Solutions:
  
  
  Check Hierarchy Configuration:
  
  Go to the hierarchy definition in the BW system and ensure that it is correctly configured.
  Verify that the hierarchy is active and has the necessary nodes and structure.
  
  
  
  Review Query Design:
  
  Open the BW query in the Query Designer and check if the hierarchy is being used correctly.
  If the hierarchy is not essential for your analysis, consider removing it from the query.
  
  
  
  Use Supported Hierarchies:
  
  Ensure that you are using a hierarchy type that is supported by HANA views. Standard hierarchies are generally more compatible than non-standard ones.
  
  
  
  Check for Data Issues:
  
  Ensure that the hierarchy has valid data and that there are no missing nodes or levels that could cause issues.
  
  
  
  Update BW and HANA:
  
  Ensure that your BW and HANA systems are up to date with the latest support packages and patches, as updates may resolve compatibility issues.
