Repeat Customers - for each Item.

[ssaadat]

Hi,

Good day to all,

I have been trying to create a measure to calculate number of repeated customers. To use in a matrix to filter for number repeated for each Item ID. I have used methods mentioned in the following links & been unfortunetly unsuccessful to get the accurate numbers confirmed using excel 

 count if $>0 (using pivot --> Num of orders:  ([Rows: Item_ID, Customer_ID] [Columns: dates] [values: bookings_$]))

then (  # Reorder: sumifs # num of orders > 1 for each Item_ID)

I have included a sample of the data similar to dataset used. 

The page is filtered for Bookings Only.

No date restriction.
