• What is the cause and solution for SAP error message BRAIN684 - Hierarchy &1 is invalid for key date &2. ?

  The SAP error message BRAIN684 indicates that there is an issue with a hierarchy that is being referenced in a query or report. Specifically, the message states that the hierarchy specified (denoted as &1) is invalid for the key date provided (denoted as &2). This typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when working with hierarchies in InfoObjects.
  Cause:
  
  Hierarchy Not Active: The hierarchy may not be active for the specified key date. Hierarchies can be time-dependent, meaning they can change over time, and if the key date falls outside the active period of the hierarchy, this error will occur.

  Data Model Changes: Changes in the data model or InfoObject settings may have affected the validity of the hierarchy.
  
  Solution:
  
  Check Hierarchy Activation: Verify that the hierarchy is active for the specified key date. You can do this by navigating to the hierarchy in the SAP BW modeling tools and checking its validity period.
  Review Key Date: Ensure that the key date you are using is correct and falls within the active range of the hierarchy.
  Re-activate Hierarchy: If the hierarchy is not active, you may need to reactivate it or create a new version that includes the required key date.
  Data Load: If the hierarchy was recently modified or deleted, ensure that the data load process has been executed successfully to reflect the changes.
  Check for Changes: Review any recent changes made to the InfoObject or the hierarchy that might have affected its validity.
  
  Related Information:
