Error Code 9375 when using PDS OutlineCodeAddValues

[Chris]

I'm writing an application to update an resource Enterprise Outline
Code using the PDS, and I'm having a problem with OutlineCodeAddValues.
I am able to successfully use the methods EnterpriseOutlineCodes and
OutlineCodeDeleteValues without any problems, but when I try to use
OutlineCodeAddValues to add a new value I am getting status code 9375
in the result. The SDK says that this status code is reserve for
DataAccess exception errors, does anyone know why I would be getting
this exception?

Here's the specific error I get in my event log, if this helps:

Component: PDS
Line: 0
Error Number: 0x249f
Description: <Description><![CDATA[CDataAccess.OutlineCodeAddValues;
-2147217873 : Cannot insert the value NULL into column 'RESERVED_DATA',
table 'ProjectServerIP.dbo.MSP_OUTLINE_CODES'; column does not allow
nulls. INSERT fails.]]></Description>

Is this a known issue?
