• What is the cause and solution for SAP error message DMCLG379 - Copy behavior "automatic" cannot be combined with another behavior ?

  The SAP error message DMCLG379 indicates that there is a conflict in the copy behavior settings for a data model or data flow. Specifically, it states that the "automatic" copy behavior cannot be combined with another copy behavior. This typically occurs in the context of data modeling in SAP BW (Business Warehouse) or SAP HANA, where different copy behaviors are defined for data extraction and loading processes.
  Cause:
  The error arises when you attempt to configure a data flow or transformation that includes multiple copy behaviors, one of which is set to "automatic." The "automatic" copy behavior is designed to handle data copying in a specific way, and it cannot coexist with other behaviors like "manual" or "delta" in the same context.
  Solution:
  To resolve this error, you need to review and adjust the copy behavior settings in your data model or transformation. Here are the steps you can take:
  
  
  Identify the Data Flow/Transformation: Locate the specific data flow or transformation that is generating the error.
  
  
  Check Copy Behavior Settings: Open the configuration for the data flow or transformation and check the copy behavior settings. Look for any conflicting settings.
  
  
  Modify Copy Behavior:
  
  If you have set the copy behavior to "automatic," consider whether you need to change it to a different behavior that does not conflict with others.
  If you need to use multiple behaviors, ensure that they are compatible and do not include "automatic" alongside others.
  
  
  
  Test the Configuration: After making the necessary changes, test the data flow or transformation to ensure that the error is resolved and that data is being processed as expected.
  
  
  Documentation and Best Practices: Refer to SAP documentation or best practices for configuring copy behaviors in your specific version of SAP BW or HANA. This can provide additional insights into how to set up your data flows correctly.
