Exporting data from Redcap to SAS: Zero observations in SAS Dataset

[ABO28]

Hello,

I am trying to export survey data from REDCap to SAS (version 9.4). After following the instructions (from REDCap) in the picture below, I opened the SAS dataset only to find that there were zero observations (i.e. no participant responses) and only variables available in the SAS dataset. However, after opening the CSV file generated by REDCap, there was no missing data. I'm not sure whether this is an issue with SAS software, or if I'm doing something wrong when exporting the data. I would greatly appreciate some insight into why SAS is reading that there are zero observations in the dataset, but the CSV file reads otherwise. Thanks!

The .SAS file is the program to read the CSV file into SAS and to create the SAS data set. 

So you ran the SAS file in SAS, after updating the path per the instructions below and it generated no data? 

Was the log error free after running the code? Can you post the log - be careful not to include any identifying information in the log please.

Yes, I ran the SAS file in SAS after updating the path and no data was generated. I noticed a few errors in the log, but I'm not exactly sure what the errors mean. It seems there may be an error with the location of the CSV file, but I copied the location straight from the properties tab in "My Documents". The log is very long, so I copy and pasted lines indicating error. I hope this will suffice.

The whole filename (including the complete path) needs to be enclosed in quotes.

Great. Thank you so much!

I have recently published a macro to export REDCap data into SAS along with formats and a data dictionary. Please see my paper, presentation, and code by filling out this survey: https://redcap.link/REDCapIsMySASFriend.

Distribution using this method allows me to distribute only the most recent version, so you can check back to this survey in the future as well.
