Hi,
You can get it from the below path
SWDC -> Browse our Download Catalog -> SAP Application Components -> SAP ERP -> SAP ERP ENHANCE PACKAGE -> EHP* FOR SAP ERP 6.0 -> IDES Version.
Note: Patching and Upgrade of IDES systems are no longer supported. IDES should only be operated as a seperate installation. Each new release requires a new installation!
Refer #799639
regards,
