Aatrix reports - How do they calculate?

We have had issues with Aatrix reports not pulling numbers correctly. I have tried to contact both Aatrix support and Sage support to see if I can find out how the numbers are calculated. Aatrix refers back to Sage saying they pull the numbers from a report Sage runs in the background. Sage support gives no help. They ask for a backup of the date and then never give me a straight answer. 

Has anyone been able to determine how Aatrix gets there numbers or have a document that lays it out?
