How To Fix R7B670 - InfoCube &1 is not SAP HANA-optimized, but only has an F-fact table

SAP Error Message - Details

• Message type: E = Error

• Message class: R7B - BW Metadata (InfoCube, InfoObject, InfoObject catalog)

• Message number: 670

• Message text: InfoCube &1 is not SAP HANA-optimized, but only has an F-fact table

What causes this issue?

InfoCube &V1& is not a SAP HANA-optimized InfoCube according to its
metadata (cube subtype = ''), but only has F-fact table &V2& and a
P-dimension table.

System Response

The check on InfoCube &V1& returned an error. InfoCube &V1& cannot be
activated.

How to fix this error?

Try to identify the root cause of the changed cube subtype and adjust it
accordingly.

Procedure for System Administrators

Activating an InfoCube where its cube subtype is not '', but it is
actually SAP HANA-optimized (it does not have dimension tables or
compressed E-fact tables) results in data loss during DDIC activation of
the F-fact table. During DDIC activation, the ABAP Database Utility SE14
will run because the F-fact table contains data. As the data types of
the F-fact table columns will be changed, data loss occurs.

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 R7B670 - InfoCube &1 is not SAP HANA-optimized, but only has an F-fact table ?

  The SAP error message R7B670 indicates that the InfoCube you are trying to use is not optimized for SAP HANA and only contains a fact table of type "F" (which typically refers to a standard fact table in BW). This can occur when you are attempting to run queries or perform operations that require HANA-optimized structures, but the InfoCube does not meet those requirements.
  Cause:
  
  Non-Optimized InfoCube: The InfoCube is not designed to leverage the capabilities of SAP HANA. It may be an older InfoCube that has not been converted or optimized for HANA.
  Fact Table Type: The presence of only an F-fact table indicates that the InfoCube is not using the optimized data structures that are available in HANA, such as the use of "C" (characteristic) and "D" (data) tables in a HANA-optimized InfoCube.
  Query Execution: The error may arise when executing queries that expect HANA-optimized InfoCubes, which can lead to performance issues if standard InfoCubes are used.
  
  Solution:
  
  
  Convert the InfoCube: The primary solution is to convert the InfoCube to a HANA-optimized version. This can be done using the SAP BW modeling tools:
  
  Use the transaction code RSA1 to access the Data Warehousing Workbench.
  Navigate to the InfoCube and check if there is an option to convert it to a HANA-optimized InfoCube.
  Follow the conversion process, which may involve creating a new InfoCube based on the existing one and ensuring that it uses the appropriate data structures.
  
  
  
  Check for HANA-Optimized Alternatives: If conversion is not feasible, consider using other HANA-optimized data models, such as:
  
  Advanced DataStore Objects (ADSO): These are designed for HANA and can replace traditional InfoCubes.
  CompositeProviders: These can combine data from various sources, including HANA-optimized structures.
  
  
  
  Review Query Design: If you are running queries, ensure that they are designed to work with the available data structures. You may need to adjust the queries to use HANA-optimized InfoProviders.
  
  
  Related Information:
  
  SAP BW/4HANA: If you are using SAP BW/4HANA, it is essential to leverage HANA-optimized data models to take full advantage of the in-memory capabilities of HANA.
  Performance Considerations: HANA-optimized InfoCubes and data models are designed to improve performance and reduce data redundancy, so migrating to these structures can lead to significant performance improvements.
  Documentation and Guides: Refer to SAP's official documentation and guides on migrating to HANA-optimized InfoCubes and best practices for data modeling in SAP BW on HANA.
  
  By addressing the issue through conversion and optimization, you can resolve the error and enhance the performance of your SAP BW system on HANA.
