Hi I want to make concatinate List.
I have this table.
Customer is determined by Product.
Supplier is determined by Product and Time(week).
Now I want to Customer-Supplier List.
But in this case, I cannot identify unique key(Customer-Supplier Lineitem).
So When I import to Customer-Supplier List, duplicate error has occured.
How can I identify it?


I know I can use IsFirstOccurrence function by making Fake Time List.
But I don't want to do this.
Do you have any idea?

I found another method.
I can import Num Lineitem From "Product List Module" to "Customer Supplier Module".
Then I can make "Customer Supplier list" uniquely.


By using this import method, Import cell will drastically increase.
Is there another simple method?
