Re: cannot import this csv using proc import

Hi Raymond, 


It's likely SAS isn't reading the correct type for the variable. 

You can try setting GUESSINGROWS=32000 or the number of records in your file so that it scans the full table before assigning a variable type.


Another option - which I generally recommend - is to look at your log after the PROC IMPORT. The Log has the import code, but in a data step format. If you copy that code, holding down CTRL+ALT while selecting to avoid line numbers, you can customize it to your needs. Specifically, check the informat/format and input statement for the variables that are causing errors in your log.


It looks like you have four specific variables causing the errors:


NOTE: Invalid data for id in line 689 1-29.

NOTE: Invalid data for lvedvi in line 689 36-55.

NOTE: Invalid data for lvesvi in line 689 58-62.

NOTE: Invalid data for rvedvi in line 689 163-178.
