I don't use SPSS but you should check which variables are regarded as string by Stata. -describe- or -varm- will tell you this. You may need to -encode- or -destring- some variables.

I have recently migrated from SPSS to Stata to allow me to implement 
fractional polynomial techniques, including the mfp procure, for a 
logistic regression analysis. I have been able to save the original SPSS 
file in Stata format. The variables in the SPSS file were of numeric 
"Type" (in the sense intended by the SPSS Variable View facility) with 
text labels linked to the numerical codes using the SPSS Value Labels 
function. On opening up the Stata version of this file, the text labels 
appear in the individual columns for the dependent and independent 
variables. When I run the code for identifying the Stata file and 
running the mfp procedure, the error code r(2000) is generated, pointed 
to an absence of observations.

Is it possible that I require to reformat the data in some way for the 
procedure to run successfully?
