Summary : 
      This SAP Note addresses the integration of purchasing processes between SAP Sourcing Solution and ECC 6.00-6.04. For effective integration, it mandates the implementation of specific support packages, varying by system release (SAPKH60016 for 6.00, SAPKH60206 for 6.02, etc.). After installation, integration settings can be activated via IMG under "Integration with Other SAP Components --> SAP Sourcing". If direct implementation of support packages is not feasible, a manual integration approach using a specially requested transport file from SAP Support (component MM-PUR-RFQ) is discussed. This note provides guidance throughout the implementation process, ensuring alignment with system requirements and safeguarding against potential inconsistencies.
