Hello @RuuddK ,
Are you using the SAS Add-In for Microsoft Office (AMO) that is provided with SAS Financial Management (SAS FM)?
One of the SAS Add-Ins for Microsoft Office applications that is contained within SAS FM, is the SAS Financial Management Add-In for Microsoft Excel.
Maybe it's the latter one that needs proper configuration for the negative numbers.
Let us know what SAS Software you are exactly using!
If you are using SAS FM indeed, then your preferred board should be:
Solutions > Risk and Fraud > Risk & Finance Analytics
rather than this Administration > Administration and Deployment board.
You can also turn to Technical Support in your country as I am not sure whether there are many SAS FM people visiting these communities.
Good luck,
Koen
