PROC EXPORT does not write out all the variables listed for the KEEP= data set option when the RENAME= data set option is also used. 

For example, three variables are listed for the KEEP= data set option, and one of the variables is renamed with the RENAME= data set option. The variable that is renamed using the RENAME= data set option is not written to the external file, but the other two variables are written to the file.

Here is an example of code that can cause this issue. In this case, only the NAME and AGE variables are written to the class.csv file:

The workaround is to use one of the data set options, RENAME= or KEEP=,  in a DATA step prior to PROC EXPORT. Then use PROC EXPORT with the other option, RENAME= or KEEP= , to create an external file.

In the following example, the RENAME= data set option is used in the DATA step and the KEEP= data set option is used with PROC EXPORT:

A fix for this issue is planned for a future software release.
