Get Exchange Rate By Merging Tables Based on the Closest Date

[Anonymous]

Dear All,

I'm new to PowerQuery and I need your help. As you can see, I have a table with my Orders (named: OrdersSA18_PowerBI) and another with my Exchange Rates (named: Exchange Rate Table) I would like to add a column to my orders table where I would have my exchange rate for each row. However, I don't have an exchange rate for each day, and I would like to otain a column in my Orders Table where the exchange rate would be the closest in terms of Date. Which means : [Order Date] <= [Starting Date]

Thank you in advance for your help 😁

Hi @Anonymous .

For Append to work, you need to have one common column in both the tables.
One solution can be using DAX.

If both of those tables are related then you can use NewColumn=RELATED(Exchange Rate Amount)
If they both are not related then you can use LOOKUPVALUE.

See dcoument below;

Yes, I had already achieved this solution using Dax, but I need this to be done in PowerQuery if it is possible of course. Thank you anyway for your fast answer.

In that case you can create a Index Column in both the tables and then merge those two tables.
1)Create Index Column in both tables by going to Add column->Index Column.
2)Perform Merge operation and select Index Columns from both tables.


Let me know if it works.

Thanks,
Sanket
