• What is the cause and solution for SAP error message RSANA_UMM_API087 - Duplicate entries provided for property '&1' ?

  The SAP error message RSANA_UMM_API087 indicates that there are duplicate entries for a specific property in the context of the SAP system's data processing, particularly related to the use of the SAP BW (Business Warehouse) or SAP Analytics solutions. This error typically arises when you are trying to load or process data that contains duplicate entries for a property that is expected to be unique.
  Cause:
  
  Duplicate Data: The most common cause of this error is that the data being processed contains duplicate entries for a property that should be unique. This could happen during data extraction, transformation, or loading (ETL) processes.
  Incorrect Data Model: The data model may not be correctly defined, leading to situations where the same key or identifier is being used multiple times.
  Data Source Issues: The source system may have inconsistencies or errors that result in duplicate records being sent to the SAP system.
  
  Solution:
  
  
  Identify Duplicates: 
  
  Check the data source for duplicates. You can run queries or use tools to identify records that have the same values for the property in question.
  Use transaction codes like SE16 or SE11 to analyze the relevant tables and identify duplicates.
  
  
  
  Data Cleansing:
  
  Remove or consolidate duplicate entries in the source data before loading it into SAP.
  If duplicates are valid in the source but not in the target, consider implementing logic to filter or aggregate the data appropriately.
  
  
  
  Adjust Data Model:
  
  Review the data model and ensure that the properties are defined correctly. If a property is meant to be unique, ensure that it is set up as such in the data model.
  
  
  
  Modify Load Process:
  
  If you are using a data load process (like a DTP in BW), ensure that the transformation rules are correctly set to handle duplicates. You may need to add logic to handle or reject duplicates.
  
  
  
  Check for Configuration Issues:
  
  Review any configurations related to the data loading process to ensure that they are set up correctly and that there are no settings that might inadvertently allow duplicates.
