Adding attachment via XML calls

Question

I am trying to associate an attachment to a punch list item via XML in C#. Whenever I try to insert an Attachment object, I am getting a generic 'Error' message back. The XML is properly formed and I am populating it with values in the same locations as a file attached via the Contract Management interface. The code to insert the punch list item works fine and it appears in the CM interface. Does anyone have any experience with this scenario? Note: I am uploading the physical file separately.

Here is an example of one that worked here. A couple comments on yours. I did not see a Base_sys_item_type in your code. Which I believe is required for this table. Usually whan I have a question about what data I need to send I'll add a record manually then duplicate what I see in the table. Another thing you should know is that the API will not receive actual files. All it currently does is create links. Files still need to be placed in the correct location. I do that here using some code that copies the files to the correct location when we load in bulk.
We are using CM on some huge projects. I have used the API to integrate and to add/delete/update hundreds of thousands of records. Each module seems to be slightly different, so be wary and always test if/how the API works. Each type can have it's own unique list of required fields etc..
