Hello,
Is there a limit to the number of simultaneous performances you can have active for scanning at one time?
The number of performances that can be active is limited only by the size of the perf_no field in the device profile table LTR_NSCAN_PROFILES (255 characters as of version 5.31 of NScan).
For best results, leave the perf_no field blank and populate the facility field with the facility ID numbers of all the various venues where performances can take place. Tessitura and NScan will auto-populate each scanner with all the valid performance numbers.
