Project Server Error Codes

Microsoft Office Project Server 2007 processes and Project Server Interface (PSI) methods have error code numbers that are generally arranged by functional area. PSErrorID lists the error code enumeration names in alphabetical order. This article lists the error codes in tables that are arranged by the PSI class or functional area and by the error ID number.

Table 1 lists the functional areas for Project Server error codes, with the general number ranges. Table 2 lists the error code number ranges in ascending order, with links to the related table. All error codes are unique; however, there are some functional areas that overlap in some error code number ranges.

For sample code that uses the PSClientError object to show a list of errors in a PSI method call, see Example.

Example

To get a list of all errors that occur if you get an exception when you call a PSI method, pass the SoapException object to the Microsoft.Office.Project.Server.Library.PSClientError class constructor. You can then use GetAllErrors to store the error information in a PSErrorInfo array and enumerate the errors, as in the following example.

Note:
The PSErrorInfo object does not include all of the information you might need. For example, if you use Resource.CheckOutResources where one of the resources is already checked out, PSErrorInfo shows the reason for failure for each resource that cannot be checked out, but does not include the resource name or GUID. For a way to get more information, see CheckOutResources.
