• What is the cause and solution for SAP error message UPWB130 - Attribute can contain max. one reference. Other references deleted ?

  The SAP error message UPWB130, which states "Attribute can contain max. one reference. Other references deleted," typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when dealing with attributes in InfoObjects or when managing master data.
  Cause:
  This error arises when you attempt to assign multiple references to a single attribute in an InfoObject where only one reference is allowed. In SAP BW, attributes can be linked to other InfoObjects, but the system restricts this to a maximum of one reference per attribute. If you try to add another reference, the system will automatically delete the previous one and throw this error message.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Attribute Settings:
  
  Go to the InfoObject maintenance transaction (e.g., RSD1).
  Select the InfoObject that is causing the error.
  Review the attributes of the InfoObject and check if there are multiple references assigned to the attribute in question.
  
  
  
  Remove Unnecessary References:
  
  If you find that there are multiple references, decide which reference is necessary for your use case.
  Remove the unnecessary references to ensure that only one reference remains.
  
  
  
  Adjust Data Model:
  
  If your data model requires multiple references, consider redesigning the model. You may need to create additional attributes or InfoObjects to accommodate the relationships you need without violating the one-reference rule.
  
  
  
  Re-activate the InfoObject:
  
  After making the necessary changes, you may need to activate the InfoObject again to ensure that the changes take effect.
  
  
  
  Test the Changes:
  
  After making adjustments, test the data loading or reporting processes to ensure that the error no longer occurs and that the data behaves as expected.
