• What is the cause and solution for SAP error message K9174 - Attribute "&" refers to several columns ?

  The SAP error message K9174, which states "Attribute '&' refers to several columns," typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when there is an issue with the definition of attributes in a data model, such as an InfoObject or a characteristic.
  Cause:
  This error arises when an attribute is defined in a way that it points to multiple columns in the underlying database or data source. In SAP BW, attributes are used to provide additional information about a characteristic, and each attribute should ideally map to a single column. If the system detects that an attribute is ambiguous and refers to multiple columns, it raises this error.
  Solution:
  To resolve the K9174 error, you can follow these steps:
  
  
  Check Attribute Definitions:
  
  Go to the InfoObject or characteristic definition in the SAP BW modeling environment.
  Review the attributes associated with the characteristic and ensure that each attribute is mapped to a single column in the data source.
  
  
  
  Modify the Data Source:
  
  If the data source (e.g., a table or view) has been modified and now contains multiple columns that could be interpreted as the same attribute, you may need to adjust the data source to ensure that each attribute is clearly defined.
  
  
  
  Adjust the InfoObject:
  
  If necessary, you can create new attributes or modify existing ones to ensure that they are uniquely defined and do not overlap with other attributes.
  
  
  
  Re-activate the InfoObject:
  
  After making changes, make sure to activate the InfoObject again to apply the changes.
  
  
  
  Check for Data Source Changes:
  
  If the underlying data source has changed (e.g., new columns added), ensure that the InfoObject is updated accordingly to reflect these changes.
  
  
  
  Test the Changes:
  
  After making the necessary adjustments, test the data model to ensure that the error is resolved and that the attributes are functioning as expected.
