Dears:
I have a table, named "Receptions", where material receptions information from multiples supplier and items are stored.
For trazeability issues, every supplier batch needs a internal batch. Of course we try to limit the amount of batches, but sometimes it happens.
In the below (and simple) example you can see the Product 1 has been received last time on July 06th, but two batches were received from Supplier 1.
| Receptions Table | (Fact Table) | |||||
| Product | Date | Price | Batch | Supplier batch | Supplier | Quantity |
| Product 1 | 06/07/2016 | 2,45 | Lot-001 | Batch 2016-1 | Supplier 1 | 250 |
| Product 1 | 06/07/2016 | 2,47 | Lot-002 | Batch 2016-2 | Supplier 1 | 250 |
| Product 1 | 05/04/2016 | 2,48 | Lot-003 | Batch 2016-3 | Supplier 1 | 500 |
This is how the table I have created looks like in PowerBI.

By using MAXA function I can find the Last purchase date.
What I can't is "the last price" for that date. In this case 2,47.
I was investigating about Lookupvalue but this functions seems to have problems when two values are found (my case, two receptions at 06 th of July with different price).
"if several rows in your table match your criteria, then VLOOKUP in Excel will only return thefirst (or last) match. On the contrary, LOOKUPVALUE in DAX may return an error if several rows match your criteria. This will occur if [OutputColumn] does not contain the same value for all matching rows".

Please I need your help to find the right expression to give me the "maximum value of price" for the "last purchase date".
