Quote Expiration Date not correct in 300 integration

The default quote expiration date in Sage 300 in 1 year. When the user creates a quote directly in Sage 300, the quote expiration date shows correctly as one year. However if they create a quote in Sage CRM, the Sage 300 webscreen shows an incorrect quote expiration date of about 6 months in the future. And it appears to be different for different users. Any idea where this is configured?
