Hi,
What is the format of your dataset ?
I have the same error with PA with a .csv dataset.
So I open my dataset directly with R. The problem is empty values are not NULL but NA. Diffrences are explained here : http://www.r-bloggers.com/r-na-vs-null/
And I have the same error when I try to launch a regression with R.
I don't know how SAP Predictive Analysis read empty data.
My answer is not complete, but I hope it helps to understand the problem and helps someone else to fix it.
You can use InfiniteInsght regression if you want to keep empty values in your dataset.

If SAP PA is passing na.action=na.pass than this will not work in R regression algorithms
That's why keep option for handling missing values is throwing following error
lm(ctl~trt,na.action=na.pass)
Error in lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) :
NA/NaN/Inf in 'x'
The above error is coming when I am running algo directly in R
