How to identify if modifiers are getting applied

Question

I am trying to define a modifer (Discount List), say Mod2, that needs to be applied only under certain conditions.
I already have another existing modifier (Discount List), say Mod1, which returns the discount% using a Dynamic formula.
The requirement is that the modifier Mod2 should apply only when Mod1 is not getting applied, or is getting applied with a discount% of 0.
My question is how can I define a qualifier for the modifier Mod2?
Is there a way for me to write custom code to see if the modifier Mo1 is getting applied, and with a discount% > 0 ? If so, what tables could I check? I tried setting up a qualifier which calls a custom pl/sql package wherein I retrieved values from qp_preq_lines_tmp, but there is no pertinent information in there.
Any help is appreciated.
Thanks.
Jay.

Hi Gerry,
I wish it was as simple as that !!
The catch is that I dont want to apply Mod2 when Mod1 gets applied with a discount% > 0. I do have lots of scenarios where Mod1 gets applied with a discount% of 0. The Mod1 discount value is derived via a dynamic formula, so it always returns a value, and I dont know how to suppress the application of the modifier if the value returned by the formula is zero. So it will always get applied. Question is, how do I get Mod2 (which by the way is a Freight and Special Charge, not Discount List - sorry for the confusion), to not apply when Mod1 discount% is > 0.
