I think obs 65458 contains some illegal character in that table, So when SAS transcode it fail,SAS will stop read in the obs after it.I meet this situation frequently.
So Check the dataset' s variable attribute. to see whether the length of some variables is
very long (e.g. 32700) or is zero.
You 'd better to open the table to see content to find whether there are some strange character.
Then drop these variables , you will successfully imported.
