Control the number of displayed lines Using DAX

[CHIJK]

I have a table showing customers and their purchase orders. I hope to have a filter to control the display of the customer’s last N purchase records, I tried to use the ISFILTER() function but I did not achieve the desired effect. any ideas?

@CHIJK ，

 What's your DAX code? I think you need to add an index column to your main table. You also need to create a new parameter table at "what if parameter", and then you can use ISFILTER() to create a metric based on this. (This blog may help you a lot)

(I suggest you provide a screenshot of the front-end report instead of the data table in the model, so that I can give a more specific solution)

Mark this post as solution if this helps, thanks!
