How to match two fields with the same values, located in different tables not relationated

[Anonymous]

Hi everydody,

Maybe someone could help me to develop this task. I´m trying to match two fields that contain the same values in one app, but they are not located in the same model. It consists on create a currency artifact with the aim of calculate the exchange rate of a huge amount of values. You can see a first view of the artifact in the file I attach here in this post.

I have decided not to create a relationship between these two tables because the second one (currency artifact) could modify the values of the other filters of the app.

Thanks in advance
