To use an option beyond the 30-day evaluation period, you must purchase and install an appropriate SAP Software Asset Management (SySAM) license.

Before installing and configuring any product edition, know which features you are licensed to use. 2.2 Product Editions ● SAP IQ Enterprise Edition Supports all options and features.
