Creating this parental association would create a loop in Accounts hierarchy.

Before starting to speak about Titan - Yes, the NDA has been lifted and there's a lot to talk about and other bloggers have just done so, I'd like to write a little bit about a problem that took me sometime to solve and I didn't find much info about it.

Here's the error message I was having:

«0x80040507
Creating this parental association would create a loop in Accounts hierarchy.
Platform»

This showed up in a migration I was building and I couldn't see why it was happening because I was filtering the chance of an Account being the Parent Account of itself on the very beggining of the process in the data I was receiving at that particular moment.

But after some research I found the problem and it got to be childish one: In the method that would return me the actual Parent Account guid, at the same time I was updating the Account's accountid with it. So I was trying to set a Parent Account link for one Account to itself. Pretty neat, hein?!
