The Preview Program offers SAP partners an opportunity to download a preview version of SAP Business One 9.1 (both on MS SQL and on SAP HANA) prior to the official Ramp-Up start. This new program is vital to the successful Ramp-Up of SAP Business One 9.1. Participating partners will have the opportunity to participate in the quality assurance process and provide SAP with feedback prior to Ramp-Up. This will give SAP time to address any software issues prior to final release.
