from data per characteristic. If a fixed filter already includes a node
from another hierarchy, it is not possible to switch the display
hierarchy.

• What is the cause and solution for SAP error message BRAIN_DEV190 - For characteristic &1 only one hierarchy with key date derivation allowed ?

  The SAP error message BRAIN_DEV190 indicates that there is an issue with the hierarchy assignment for a characteristic in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence). Specifically, it states that for the characteristic specified (denoted by &1), only one hierarchy with key date derivation is allowed.
  Cause:
  This error typically arises when:
  
  Multiple Hierarchies: You have defined multiple hierarchies for a characteristic that are set to use key date derivation. SAP allows only one such hierarchy for a characteristic.
  Configuration Issues: There may be a misconfiguration in the InfoObject settings or in the hierarchy settings for the characteristic.
  Data Model Conflicts: Conflicts in the data model where multiple hierarchies are trying to derive values based on the same key date.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Hierarchies:
  
  Go to the InfoObject maintenance for the characteristic in question.
  Check the hierarchies assigned to the characteristic. Ensure that there is only one hierarchy that is set to use key date derivation.
  
  
  
  Modify Hierarchy Settings:
  
  If you find multiple hierarchies, you will need to either delete or deactivate the additional hierarchies that are not needed or change their settings to not use key date derivation.
  
  
  
  Adjust Key Date Derivation:
  
  If you need to keep multiple hierarchies, consider adjusting the key date derivation settings to ensure that only one hierarchy is set to derive values based on the key date.
  
  
  
  Transport Requests:
  
  If changes are made in a development environment, ensure that they are properly transported to the production environment.
  
  
  
  Testing:
  
  After making the necessary changes, test the data loading or reporting process again to ensure that the error is resolved.
