Difference reports, use saved versions of a report format to calculate the difference in records between two versions of the same report printed at two separate times. Each line item represents a record that has a change in quantity from one version of the report to the other.

In order to be able to run a difference report, previously cataloged reports must have YES chosen on their screen 5 diff report filter. Choose a report and press Modify.

Go to Screen 5 on the top menu bar. Make sure the option for Diff Report is set to YES.

Instead of navigating to the Difference Reports area, wherever you see the Diff Report button on a saved report file, you can choose that button instead.

You will be asked to create or choose a format for the difference report. Note that this does not override the report format of the (for example) Net Physical report you are using to print the difference report; this Difference Report format allows you to choose how to display the data on the difference report itself.

Select a report or create a new one and print as usual.

You will see a list of the items that have differing quantities from one report to another. Items that go off an older report have an old quantity of X (some value) and a new quantity of 0.00. Items that exist on the new version but not on the old one have an old quantity of 0.00 and a new quantity of X.
