• What is the cause and solution for SAP error message R8005 - Assigned unit field &1 must have InfoObject type UNI ?

  The SAP error message R8005, which states "Assigned unit field &1 must have InfoObject type UNI," typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when there is an issue with the data model, specifically related to the characteristics of the InfoObjects being used.
  Cause:
  The error indicates that a field that has been assigned as a unit field in a data model (like a query or an InfoCube) is not of the expected InfoObject type. In SAP BW, unit fields should be associated with InfoObjects that are defined as "UNI" (unit of measure). If the assigned field is of a different type (for example, a characteristic or key figure), this error will be triggered.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the InfoObject Definition:
  
  Go to the InfoObject maintenance transaction (e.g., RSA1 or RSD1).
  Locate the InfoObject that is causing the error (indicated by &1 in the error message).
  Ensure that it is defined as a unit of measure (InfoObject type UNI).
  
  
  
  Modify the Data Model:
  
  If the InfoObject is not of type UNI, you may need to either change the InfoObject type to UNI (if appropriate) or assign a correct unit InfoObject to the relevant field in your data model.
  If you are using a characteristic or key figure where a unit is expected, you may need to create a new InfoObject of type UNI to represent the unit.
  
  
  
  Reassign the Unit Field:
  
  After ensuring that the correct InfoObject is defined, go back to the data model (e.g., InfoCube, DSO, or query) and reassign the unit field to the correct InfoObject.
  
  
  
  Activate the Changes:
  
  After making the necessary changes, activate the InfoObject and the data model to ensure that the changes take effect.
  
  
  
  Test the Changes:
  
  Run the query or data model again to verify that the error has been resolved.
  
  
  
  Related Information:
