Open the Smartlist under Financial > Account Transactions and click Modify to open Smartlist Builder.
Call it Account Transactions MultiCompany or something like that.
Add the Calculated Field for Company Name and include it in the defaults.
Go to the new report in Smartlist and filter it for a specific segment to return a smaller number of records for testing, but one that is used by multiple companies.
What happens to us:
The company we are logged into has multiple records for the same Journal number.
Log into a different company and now that company will have duplicates but the previous one will be fine.
Why does this happen?
I removed the Company Name calculated field and I get the same results.
