Did anyone see wrong information in the System Information before? In this one, the value of the bill increased, while our script can't do that. The only change we can do is to certain items, and those items have zero value now. So the script could decrease the value, not increase it.

Is it possible your RESTlet triggered a User Event or WorkFlow that made the change? If so, I'm not sure that would reflect in the systemnotes correctly.

I check all the scripts written by us, and the rest are locked. Never mind, I opened a support case, and will see what they will say.
