Is it possible to build and export SCA in a lower version

Hi All,

I have built a BPM in NWDS 7.31  SP11 which is on Compiler version: 4.7 . My SAP PO system is a 7.4 SP8  which is on runtime version 4.6 .

I exported the SCA file and tried to deploy the it in the "Deploy" perspective , I get the expected -

java.io.IOException: Could not instantiate network DA9D141412328479689D7B679549F6BA/TechnicalError.

The given process model was built with a NWDS or development track of a higher version than the target runtime. Revision number of built process model: 4.7. Revision number of process runtime: 4.6. Please refer to SAP note 1600131 for details.

Is it possible for me to manually "select" a lower version (say 4.6) in NWDS so that the SCA is compatible with the Java runtime system ?  I am not using NWDI , all development is local .
