• What is the cause and solution for SAP error message R7B420 - Attribute &1 must be a pure display attribute. ?

  The SAP error message R7B420, which states "Attribute &1 must be a pure display attribute," typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when dealing with InfoObjects or attributes in a data model. This error indicates that the attribute you are trying to use is not defined correctly as a display attribute, which is necessary for certain operations or configurations.
  Cause:
  
  Incorrect Attribute Definition: The attribute in question (&1) is not defined as a "pure display attribute" in the InfoObject settings. A pure display attribute is one that is used solely for display purposes and does not have any associated key figures or data that can be aggregated.
  Data Model Configuration: The error may arise from the way the data model is configured, particularly if the attribute is being used in a context where a display-only attribute is required.
  Incompatibility with Queries: If you are trying to use this attribute in a query or report where only display attributes are allowed, the system will throw this error.
  
  Solution:
  
  
  Check Attribute Settings:
  
  Go to the InfoObject maintenance transaction (e.g., RSD1).
  Locate the InfoObject that corresponds to the attribute in question.
  Ensure that the attribute is marked as a "display attribute" in the settings. You can do this by checking the "Display" checkbox in the attribute settings.
  
  
  
  Modify Data Model:
  
  If the attribute is being used in a data model (e.g., in a Composite Provider or a Calculation View), ensure that it is appropriately defined as a display attribute.
  If necessary, create a new attribute that is defined as a pure display attribute and use that in your model instead.
  
  
  
  Review Query Design:
  
  If the error occurs in a query, review the query design to ensure that the attribute is being used correctly. Make sure it is placed in the right context where display attributes are expected.
  
  
  
  Transport Changes:
  
  If you have made changes to the InfoObject or data model, ensure that these changes are transported correctly to the relevant system (e.g., from development to production).
