• What is the cause and solution for SAP error message DMC_RT_MSG140 - Write behaviour 4 - no data written to the receiver in case of duplicates ?

  The SAP error message DMC_RT_MSG140, which indicates "Write behaviour 4 - no data written to the receiver in case of duplicates," typically occurs in the context of data replication or data transfer processes within SAP Data Management or SAP Data Intelligence. This error is related to how the system handles duplicate records during data writing operations.
  Cause:
  The error arises when the data replication or transfer process encounters duplicate records that violate the defined write behavior settings. Specifically, "Write behaviour 4" indicates that the system is configured to not write any data to the target (receiver) if duplicates are detected. This is often a safeguard to prevent data integrity issues, ensuring that only unique records are written to the target system.
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Review Write Behavior Settings:
  
  Check the configuration of the data transfer or replication process. If you want to allow duplicates, you may need to change the write behavior setting from "Write behaviour 4" to a different option that allows for duplicate records (e.g., "Write behaviour 1" or "Write behaviour 2").
  
  
  
  Data Cleansing:
  
  Before the data transfer, implement a data cleansing process to remove or consolidate duplicate records in the source data. This can be done using data quality tools or scripts to ensure that only unique records are sent to the target.
  
  
  
  Modify Data Flow Logic:
  
  If applicable, modify the data flow logic to handle duplicates appropriately. This could involve using aggregation functions or deduplication techniques to ensure that only unique records are processed.
  
  
  
  Error Handling:
  
  Implement error handling mechanisms in your data flow to log and manage duplicates. This can help you identify and address the root cause of duplicates in your data source.
  
  
  
  Consult Documentation:
  
  Refer to the official SAP documentation for your specific version of the software to understand the implications of changing write behavior settings and to ensure compliance with best practices.
  
  
  
  Related Information:
  
  SAP Data Management: Understanding how SAP handles data replication and transfer can provide insights into configuring write behaviors effectively.
  Data Quality Tools: Familiarize yourself with tools that can help in data cleansing and deduplication, such as SAP Data Services or third-party solutions.
  SAP Community: Engaging with the SAP Community can provide additional insights and solutions from other users who may have encountered similar issues.
  
  By addressing the root cause of the duplicates and adjusting the configuration as needed, you should be able to resolve the DMC_RT_MSG140 error and ensure successful data writing operations.
