In Level 2 Model Building : Conclusion, there's an 'Activity: Prepare Data Exports' that tell us to Create Shipping Export Module and Create a Saved View. I've made the formula and choose the format and summary method but I'm not sure if it was right.
Here is the blueprint of my INV05

And here is the screenshot of the learning that asked me to not use the formule for the code and make a saved view
I don't know how to show the code in the line item without using formula and I don't know which summary method to use to make the saved view. Can you tell me how to do it all? and what do you think of my subsidiary and all of the formula that I use? please reply to this ASAP
( I've been so late to pass my level 2.
