As I am moving an existing website into DNN, one of the modules that I have needed to use is the User Defined Tables. It's a great module, and it very easily fits my need, save for one thing: Data Imports. The functionality that the module is replacing has a LOT of existing data, and I just don't fancy inputting all of it by hand. I can make an export routine that will export it into the XML format that DNN 4.6 uses, but I have a couple of questions that need to be answered before I go charging ahead.

1. Do I need to worry about generating the uinque ID values in the <UserDefinedRowId> field?
2. How exactly are the values in the "*UDT_Ticks" fields derived?
3. Am I going to kill anything by importing a bunch of data?

Is it possible to schedule regular imports of data? If so, how is the specific module addressed in the scheduler?

Also, I'm not having much luck with the data import. I've gone through the XML file and it's laid out right, but when I try to import data there is nothing imported and no error messages are shown. If needed, I can post the formats of both the sample data XML and what my data export is generating.

Your problem is diveded in two parts, one is imprting UDT data, the other one is to schedule a job. This is not related aany more to the UDT module itself.

DotNetNuke has the capability to run scheduled jobs. Jobs need to inherit from DotNetNuke.Services.Scheduling.SchedulerClient. I hope that helps you for your next steps, I never went that way. Please try your luck inside the developing forum (and don't tell them any thing about UDT - now you need to unterstand scheduling first)
