We can use quotation marks in the part number description, but not the part number itself.  Got the same error message.

Since it will also break reports, exports, imports, and transfer of data to other programs, I would suggest removing the characters from both part numbers and descriptions. When working with data stored in databases (except in large text fields), it is good practice to avoid using special characters such as ('"{}[]&%$#/\) Even if programs can handle these characters they will slow searches, break alphabetization and cause programmers to charge extra
 

Thanks Colin and Lynn. I will start changing the offending part numbers.
