Please have a relook.
For example here I am doing Left Outer Join hence getting all the Order IDs from the left table and occasional Nulls with Order ID Returns (see below)
You can try this , I am using default sample superstore that even you have there
Also please note that , for example if all the Order IDs are returned Left Outer Join will look like an Inner Join
I have also created my own videos on Joins here --> Joins with Troubleshooting Tableau Part 1 (Live Scenario ) - YouTube , hope it
Please mark the answer as correct and helpful if it really helped you so that it can help others as well.
I had the same problem. However, when I increased the rows to 5000, I was able to see the null rows like the video. Perhaps they used a smaller data set for the video than in the example data set.
