• What is the cause and solution for SAP error message WGDS_PROCESS750 - ML training data has already been extracted for model &1 ?

  The SAP error message:
  WGDS_PROCESS750: ML training data has already been extracted for model &1
  
  Cause:
  This message occurs when you attempt to extract machine learning (ML) training data for a model that already has training data extracted previously. In SAP systems that support ML scenarios (such as SAP Data Intelligence, SAP AI Core, or embedded ML in SAP S/4HANA), the training data extraction process is designed to be done once per model version or scenario to avoid duplicate or conflicting data sets.
  The system detects that the training data extraction step has already been completed for the specified model (&1 is the placeholder for the model name or ID), and therefore it prevents re-extraction to maintain data consistency and integrity.
  
  Solution:
  
  
  Check if re-extraction is necessary:
  
  Usually, you do not need to extract training data again unless you want to retrain the model with updated or corrected data.
  
  
  If you want to update the training data:  
  
  You may need to create a new version of the ML model or scenario in the system. This allows you to extract fresh training data without conflicts.
  Alternatively, delete or reset the existing training data extraction status for the model if your process allows it (this depends on the specific SAP ML framework or application you are using).
  
  
  
  Consult the ML model lifecycle management:
  
  Use the SAP tools or UI (e.g., SAP Fiori apps for ML model management, or transaction codes related to ML scenarios) to manage model versions and training data extraction.
  
  
  Check SAP Notes and documentation:
  
  Sometimes, specific SAP Notes provide guidance on how to handle training data extraction issues for particular ML scenarios.
  
  
  
  Related Information:
  
  This message is part of the SAP ML framework's safeguards to prevent overwriting or duplicating training data.
  The exact transaction or app where this message appears depends on the SAP product and ML integration (e.g., SAP S/4HANA embedded ML, SAP Data Intelligence).
  If you are using SAP AI Core or SAP AI Foundation, managing model versions and training data extraction is done via their respective interfaces.
  For troubleshooting, check logs and trace files related to the ML training data extraction process.
  SAP Help Portal and SAP Community can provide scenario-specific guidance.
  
  
  Summary:
  
  The error means training data extraction has already been done for the model. To proceed, either use the existing data, create a new model version for fresh extraction, or reset the extraction status if supported. Always ensure you follow the ML model lifecycle best practices in your SAP environment.
