• What is the cause and solution for SAP error message R7284 - InfoObject &1 is referenced - cannot change data type to DATS or TIMS ?

  The SAP error message R7284 indicates that you are trying to change the data type of an InfoObject to either DATS (date) or TIMS (time), but the InfoObject is currently being referenced in a way that prevents this change. This typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when dealing with InfoObjects in the data model.
  Cause:
  
  Existing References: The InfoObject is being used in existing data models, such as InfoCubes, DataStore Objects (DSOs), or queries. Changing the data type of an InfoObject that is already in use can lead to inconsistencies in the data model.
  Data Flow Dependencies: The InfoObject may be part of a data flow that includes transformations, data sources, or other objects that depend on its current data type.
  Data Type Restrictions: Certain InfoObjects may have restrictions based on their usage in the system, and changing the data type could violate these restrictions.
  
  Solution:
  
  
  Check Dependencies: Before attempting to change the data type, check all dependencies of the InfoObject. This includes:
  
  Queries that use the InfoObject.
  Data models (InfoCubes, DSOs) that include the InfoObject.
  Transformations and data sources that reference the InfoObject.
  
  
  
  Remove References: If possible, remove or adjust any references to the InfoObject in the data models or queries. This may involve:
  
  Deleting or modifying queries that use the InfoObject.
  Adjusting transformations or data sources that reference the InfoObject.
  
  
  
  Change Data Type: Once all references have been removed, you can proceed to change the data type of the InfoObject to DATS or TIMS.
  
  
  Recreate Dependencies: After changing the data type, you may need to recreate or adjust the dependencies that were removed. This includes re-adding queries, transformations, and data sources.
  
  
  Testing: After making changes, thoroughly test the data model to ensure that everything functions correctly and that there are no issues with data integrity.
