Customer Group Prices

Did you have a solution to limit discount codes on Customer Group Prices?

No sorry, it's hard for multiple discount addons to coexist. Can you describe better what you mean by limiting?

Since customer group prices are special cases, I want to keep the discount code outside of these groups. For example, dealers who shop wholesale. In short, it would be good to be able to set the discount code active / passive for customer groups.
if ($customer['group_id'] == 2) return;
I don't know if it's possible with a solution like this. I haven't had a chance to examine it yet.

Yeah you could use that. Put it in ot_discount_code and om_discount_code.
If group id is not propagated, use reference::customer($customer['id'])->group_id.

İts propagated. Thank you
