I also created a feature ticket: https://issues.shopware.com/issues/NEXT-24673, so that the customer can follow the processing

If a shop operator has several promotions running at the same time, it is difficult to check or exclude the interactions.

A special example: For certain product groups there is a buy X get Y promotion. In addition, there is a promotion that grants a percentage discount. Correctly, the percentage promotion does not take into account the 100% discount from the previous promotion. However, the 100% discounted product is included in the total for the percentage discount, so that this product is discounted by over 100%.

Since it can be intentional that several promotions are applied at the same time, but should not be cumulated, the "Do not combine with" settings of the voucher do not help. For one rule, I have to make sure that I include it in all active promotions, but there is no way to query this case "If item already discounted, then ....".

Please check and implement how the multiple unwanted discounting can be stopped in a simple way.
