Is this about what your data set looks like?
MemberNum x t.x T.cal m.x T.star h.x h.m.x e.trans e.spend

I've had this exact problem a few times. It has nothing to do with a table not being found on the channel. From my experience, sqlSave has trouble with dates and scientific notation. Try converting x to a factor:
new_data$x = as.factor(new_data$x)
and then sqlSave. If that doesn't work, try as.numeric
and even as.character
(even though this isn't the format that you want.
