Service Contract and lines importing via DTW

Hi Experts,

I've been trying to import Service Contracts into B1 with DTW. I cannot seem to get the ContractID correct and have tried various solutions.

This is the first import, therefore I believe that I can use a key of 1,2,3,4 and keep the LineNum empty in the lines document.

I get the error: <ErrorList><Error>System Id = 318365040, Line Number = 1, Column Number = 79, Description = The namespace of the element 'schema' must be from the schema namespace.

The Customer Equipment Cards that are referenced in the Contract lines (Manufacturer SN) are already imported.

Regards,

Marli
