We have a PHP web app talking to SF. We have converted a Lead to an Account, and are then trying to update the account and getting the error when playing in the sandbox:
Sales Force Update object Failed: attempt to violate hierarchy constraints
Unfortunately, there's no documentation on this error anywhere, and it seems like we're the only ones getting it.
Can anyone shed some light on what this means? The same code works fine when talking to the live SalesForce.
