Programmatically re-login to Epicor when session is expired

Epicor ERP 10
1

Anyone has tried to programmatically re-login to Epicor? We have an issue even tho our session timeout is set to entire day, we still randomly experience session getting expired. We have a stand alone application that uses Epicor BOs and we have a session object that logs the application into Epicor and then we use various BOs to perform some tasks.

Here is a code I use but it crashes with the error below:

And here is the error:

I’m no expert, but if you are “re logging in” and the guid already exists it’s going to throw that error if the session with that guid already exists. Wouldn’t the new guid be all 000’s. As I said no expert, but that error, seems to be saying it’s doing what’s on the box.

Is there any other way I can login without using GUID?

This sounds promising… But as I said no expert in this aspect of things. I think I have done a session impersonation once in code

or this
