When I used the old free SAP .net connector, I was able to pull SAP negative numbers (with the negative sign as a suffix) and put them into a SQL Server table properly.
Using the exact same SQL SELECT statement (BizTalk Adapter Pack .Net Data Provider for mySAP Business Suite), I get a "?" in my output SQL Server table (or a <Error displaying this cell> when previewing the output from within my SSIS package).
Is there a setting I'm missing? I searched for several hours and found no reference even close to this problem. I'm thinking it must be something obvious I'm missing.
