• What is the cause and solution for SAP error message UJR_EXCEPTION025 - Cannot perform delta-write without duplicate check ?

  The SAP error message UJR_EXCEPTION025 indicates that there is an issue with the delta write process in the context of SAP's data replication or data warehousing scenarios, particularly when using the SAP Data Warehouse Cloud or SAP BW (Business Warehouse). This error typically arises when the system detects potential duplicate records during a delta write operation, which is meant to update existing records without reprocessing all data.
  Cause:
  The error occurs due to the following reasons:
  
  Duplicate Records: The system has identified that the data being processed contains duplicate records that could lead to inconsistencies in the data warehouse.
  Missing or Incorrect Delta Mechanism: The delta mechanism may not be correctly configured, leading to issues in identifying unique records.
  Data Source Issues: The source data may have duplicates that are not being handled properly.
  Incorrect Key Configuration: The key fields used for identifying unique records may not be correctly defined, leading to the system's inability to perform a duplicate check.
  
  Solution:
  To resolve the UJR_EXCEPTION025 error, you can take the following steps:
  
  
  Check for Duplicates:
  
  Review the data being loaded to identify any duplicate records. You can use SQL queries or data profiling tools to find duplicates in the source data.
  Ensure that the data source does not contain duplicates before the delta write operation.
  
  
  
  Configure Delta Mechanism:
  
  Ensure that the delta mechanism is correctly configured in your data flow. This includes setting up the correct delta indicators and ensuring that the data source is capable of providing delta information.
  
  
  
  Review Key Fields:
  
  Check the configuration of key fields in your data model. Ensure that the fields used to identify unique records are correctly defined and that they align with the source data.
  
  
  
  Data Cleansing:
  
  If duplicates are found, consider implementing data cleansing processes to remove or consolidate duplicate records before they are loaded into the data warehouse.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or support notes related to the specific version of SAP you are using. There may be specific guidelines or patches available that address this issue.
