		Hello, 
Can you please advice me right solution, how to realize "outer apply with top 1" in qliksense? 
I have 2 tables in qvd files (Sales and Price list)
I need to get result table: Sales + Price on document date
1. Sales 
| Date | Nr | Product | Qty | 
| 2023.02.28 | 0000000445 | Gas | 5 | 
| 2023.03.14 | 0000000446 | Gas | 12 | 
| 2023.03.25 | 0000000447 | Gas | 6 | 
2. Price list 
| Date from | Product | Price | 
| 2023.03.15 | Gas | 10.55 | 
| 2020.01.01 | Gas | 07.15 | 
in sql i can do next: 
select
	sales.date,
	sales.nr,
	sales.product,
	sales.qty,
	pricelist.price
from
	sales
	outer apply (
		select top 1
			pricelist.price
		from
			pricelist 
		where
			pricelist.product = sales.product
			and pricelist.date <= sales.date
	) as pricelist
	
Result table by sql:
| date | nr | product | qty | price | 
| 2023.02.28 | 0000000445 | Gas | 5 | 10.55 | 
| 2023.03.14 | 0000000446 | Gas | 12 | 07.15 | 
| 2023.03.25 | 0000000447 | Gas | 6 | 07.15 | 
but how to do same in qliksense? 
left join or applymap with date condition?

		@vv you can use intervalmatch like this
Data:
LOAD
    "Date",
    Nr,
    Product,
    Qty
FROM [lib://comm]
(html, utf8, embedded labels, table is @1);
price:
LOAD
    "Date from",
    Product,
    Price
FROM [lib://comm]
(html, utf8, embedded labels, table is @2);
price_final:
Load *,
     date(if(Product<>Previous(Product),Today(), Previous("Date from")-1)) as "Date to"
Resident price
Order by Product,"Date from" desc;
Drop Table price;
left Join(Data)
IntervalMatch ( "Date", Product )
LOAD "Date from", "Date to", Product
Resident price_final;
Left Join(Data)
Load * Resident price_final;
Drop Table price_final;
Drop Fields "Date from", "Date to";
