@Kavika F @Felix Möhlmann I now have two ways to act but I want to merge the two ways. I don't know how I should do it, and I have a new idea. I want to know if I can set the action to not act according to my arrival. table is carried out. All in all, I want to have three methods (1. spt, etc. scheduling methods), (2. Randomly grab my general product category as demonstrated in the tutorial) (3. Start with my first one without doing any action. Actions are performed in scheduled order)
