Hi Suresh,
Now I have taken only this new transformations ( Between Z_STK and 0RT_C37) in to the new transport request and transported from development to Production. But post transportation this new transformations are not reflecting.
After you release the transport from Devlopment system, have you imported to production? via t.code: STMS, choose your transport and then release? if you don't import in production, then you wont be able to see the newly created transformation.. please check.
