The service getAssociatedPriceRulesConds return some element to help the selection on product prise rule condition screen.
The problem: all query to resolve element are realized without filter :
On big database, a call on this service generate a server saturation (load 1 Million product to a dropdown, isn't logical)
To keep the benefit of this service as example to implement a custom service with filter, I introduce a limit range to 200. For much more it's better to improve the screen with a lookup.
