Products by Customer, in a Desnormalized table.

[Anonymous]

Hi

I have a table with customer AND products in the same table. This table has many fields, about 20. 

CustomerID	ProductID	FieldN..
50	            1	
51	            1	
52	            1	
53	            1	
54	            1	
54	            2	
55	            1	
55	            2	
56	            1	
56	            2	
56	            3	
56	            4	

I need to create a graph to show the Number of Customer vs Number of Products they have.

How can I achieve that?

Hi,

You can easily reach this by distict count Product ID that each customer has.

Hope this helps.

Even if you have a denormalised table, always look to model your data in Power BI to take advantage of performance optimisations and a simpler syntax in DAX, amongst many other reasons : (read this: https://docs.microsoft.com/en-us/power-bi/guidance/star-schema).

Then create measures for Total Customers and Total Products, and add new measures against your data held in your product and customer dimension tables 

Please add Kudos if this helps.

The trouble is that the table don't have a key.. I've tried to find a key, but there are many text fields that should be concatenated to create a key, making a really big key and by so, a big model. Is there any way to reduce this giant concatenated key?

I came from Qlikview, and there I used a function called "Autonumber", to automatically create a short key for each distinct row.. but here I can't find something similar

Thanks!
