Not sure off hand. I know there might be a setting in the tracking group. The statement below is from Micros 3700 POS Configurator Manual.pdf.
When setting up tracking groups, keep in mind that you can create up to 64 tracking totals in a group, but only 48 will print on Micros standard reports. The system records information for the remaining tracking totals, but you must create a custom report to print it. See the 3700 Custom Reports Design Manual for further information on creating custom reports.
I do not have the '3700 Custom Reports Design Manual', maybe someone else does. It should be able to get more from it.
