So all you need to do is to change the src path in the index.html file. Finally, the app can consume resources from the library. Conclusion In this blog, I have demonstrated how to consume a custom UI5 library in BAS or VS Code (locally). Please note that this app is not yet rea...
num_instance_by_accompanying_product = accompanying_products_by_order.groupby(“product_id”)[“product_id”].count().reset_index(name=“instances”) To give some perspective on what this looks like, let’s consider the output from passing the value 3 (as the product ID) to this function....
