• What is the cause and solution for SAP error message BRAIN891 - InfoObject &1 must not be used in the drilldown ?

  The SAP error message BRAIN891 indicates that a specific InfoObject (denoted as &1) is not allowed to be used in the drilldown of a query. This typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when creating or executing queries in the BEx (Business Explorer) Analyzer or Query Designer.
  Cause:
  The error can arise due to several reasons:
  
  InfoObject Characteristics: The InfoObject in question may be defined as a "key figure" rather than a "characteristic." Key figures are typically used for aggregations and calculations, while characteristics are used for drilldown and filtering.
  Query Design: The InfoObject may not be included in the query definition as a characteristic that can be used for drilldown.
  Restrictions in the InfoObject: The InfoObject may have specific settings or restrictions that prevent it from being used in drilldown scenarios.
  Hierarchy Issues: If the InfoObject is part of a hierarchy, it may not be allowed in the drilldown depending on how the hierarchy is defined.
  
  Solution:
  To resolve the BRAIN891 error, you can take the following steps:
  
  
  Check InfoObject Type: Verify that the InfoObject is defined as a characteristic and not a key figure. If it is a key figure, consider whether it should be used in the drilldown or if it should be replaced with a characteristic.
  
  
  Modify Query Design:
  
  Open the Query Designer and check the structure of your query.
  Ensure that the InfoObject is included in the "Rows" or "Columns" section of the query as a characteristic.
  If it is not included, add it to the appropriate section.
  
  
  
  Review InfoObject Settings: 
  
  Go to the InfoObject maintenance in the SAP BW system and check the settings for the InfoObject.
  Ensure that there are no restrictions that prevent its use in drilldown.
  
  
  
  Check Hierarchies: If the InfoObject is part of a hierarchy, ensure that the hierarchy is correctly defined and that the InfoObject can be used in the context of the query.
  
  
  Consult Documentation: Review SAP documentation or notes related to the specific InfoObject and its usage in queries to understand any limitations or special configurations.
  
  
  Testing: After making the necessary changes, test the query again to see if the error persists.
