Hi Phani,
Error RC - 8 Mean some thing wrong with collected objects.
so lets try to reimport your TR at Prod.
if it gives same error then again collect object from Dev and move to Prod.
but while collecting your changes, please collect all elements like CKf,RKF,EXits,variables..etc.
From RSA1-->transport connection.
use grouping option as Only necessary objects.
from middle pane, you can drga your bex query into right side screen.
at right side-->expand your collected query and select all objects which are part of your query and collect into new Tr.
Thanks
