This message serves as a warning that the changes you are making will lead to the deletion of dependent data.
  Cause:
  
  Modification of Primary Data: You are trying to modify a primary data record (e.g., a material master record) that has dependent records (e.g., purchase orders, production orders) linked to it.
  Data Integrity: SAP is designed to maintain data integrity, and changing primary data can lead to inconsistencies if dependent records are not handled properly.

  Use Change Management: If applicable, use change management processes to handle the changes in a controlled manner, ensuring that all stakeholders are aware of the implications.
  Consult Documentation: Refer to SAP documentation or consult with your SAP support team for specific guidance related to your system configuration and the changes you are making.
