• What is the cause and solution for SAP error message RS2HANA_VIEW180 - Query contains unsupported time characteristic hierarchies ?

  The SAP error message RS2HANA_VIEW180 indicates that the query you are trying to execute contains unsupported time characteristic hierarchies. This typically occurs when you are working with SAP BW (Business Warehouse) queries that are being executed in a HANA environment, and the query includes time characteristics that are not compatible with the HANA database.
  Cause:
  
  Unsupported Time Characteristics: The query may include time characteristics that are defined with hierarchies that are not supported in the HANA environment. For example, if you have a time dimension that uses a hierarchy (like Year > Quarter > Month) and the HANA database does not support this structure, you will encounter this error.
  Incompatibility with HANA: Certain features or configurations in BW queries may not be fully compatible with HANA, especially if they rely on specific BW functionalities that do not translate well to HANA's data model.
  
  Solution:
  
  Review the Query: Check the query definition in the BW system. Look for any time characteristics that are using hierarchies. You may need to remove or modify these hierarchies.
  Use Flat Time Characteristics: Instead of using hierarchies, consider using flat time characteristics (like Year, Month, Day) without any hierarchical structure. This can help ensure compatibility with HANA.
  Modify the InfoObject: If the time characteristic is defined as a hierarchy in the InfoObject, you may need to adjust the InfoObject settings to remove the hierarchy.
  Check for Updates: Ensure that your SAP BW and HANA systems are up to date with the latest support packages and notes, as SAP may have released updates that improve compatibility.
  Consult SAP Notes: Look for specific SAP Notes related to this error message. SAP frequently publishes notes that provide guidance on resolving specific issues, including compatibility problems between BW and HANA.
  
  Related Information:
  
  SAP BW on HANA: When migrating from traditional BW to BW on HANA, it is essential to understand the differences in how data is handled and the limitations that may arise.
  SAP Documentation: Refer to the official SAP documentation for BW and HANA for best practices on query design and compatibility considerations.
  SAP Community: Engage with the SAP Community forums where other users may have encountered similar issues and can provide insights or solutions.
  
  By addressing the unsupported time characteristic hierarchies in your query, you should be able to resolve the RS2HANA_VIEW180 error and successfully execute your query in the HANA environment.
