Transfer Packages from SAP NetWeaver 7.3 to SAP NetWeaver 7.3 EHP1
Concept
The metadata concept for packages and package interfaces was changed significantly in SAP NetWeaver releases higher than 7.10. To transport packages or package interfaces from SAP NetWeaver 7.3 to SAP NetWeaver 7.3 EHP1, you need to follow a specific procedure that creates metadata in the old format before attempting a downport.
Features
If you have a modifiable transport request of the type Transport of Copies containing any R3TR DEVC (package data) or R3TR PINF (package interface data) entries, and you want to import this transport request into a 7.31 system, you first need to start the SPAK_CREATE_HYBRID_PACK_DATA program on your 7.30 system. This program creates hybrid package and package interface data for the modifiable transport request, starts the release of the transport request, and then immediately deletes the hybrid package and package interface data from the database tables.
Process
You can find information on how to start and execute the migration process in the documentation of the SPAK_CREATE_HYBRID_PACK_DATA program. In transaction SA38, call the program and use the Report Documentation pushbutton to display the documentation.
