TOPIC: How To Prevent Paying Difference In Change Record Option

In DT Register 2.7.5...

I have a client that increases the cost of their event every 3 months by $AA (Month-2= $AB.... Month-3 = $AC. We have also enabled Joomla user creation at each registration. We also enabled the ability to change records with a change fee of $XX amount.

Currently If a person registers on Month-1 and pays $AA amount and comes back to the site on Month-3 to change something, we would want to charge them $XX amount only. However as the result of the cost change we did 3 months later, the system is now requesting that the person pay the fee of $XX.... plus the difference of the event ($AC minus $AA).

Is there a way to prevent this?

Price calculations in the user panel are done dynamically so if you are manually changing the price of the event at different points, then the user panel is going to use whatever the stated event price is when they come back to edit. There is no way to disable this... would require code modifications.
