RE: SmartList with negative total value
As far as I can find, we haven't seen this issue with SmartList Designer...
Can you give us more information on exactly how you're setting up the custom SmartList, or are you using custom tables as well to pull information from?
When the custom SmartList runs, if you use a dexsql.log, it should show a name of a SQL view or a SELECT statement that it is using to pull the information and you could potentially use that view or query to track where the information is being pulled from and to why it may be showing negative values.
As always, if you have third-party products, try setting up a 'clean' Dynamics GP instance without them and see if you can re-create this issue.
Otherwise, if you're pulling from GP tables for this custom SmartList, let us know how you're setting it up and we can test to see if we can re-create what you're seeing.
Thanks
