If you are using SAS Enterprise Guide in a non-English language, the generated code for a Between filter might use the wrong format for the start and end dates. The issue occurs in only the 32-bit version of SAS Enterprise Guide. Here is an example of 32-bit SAS Enterprise Guide running in Italian.

In the following display, the value 31/12/2015 is entered for Val. iniziale. However, this date is not specified correctly in the filter shown beneath the two fields.

This is how the generated PROC SQL appears.

As a workaround, you can use the 64-bit version of SAS Enterprise Guide, or you can enter dates using the English format. In the following example, the date 31Dec2015 is entered as 12/31/2015 instead of as 31/12/2015 and the code is correct.
