I have related two custom sql query in Tableau (via making relationship)
The outcome of the queries looks like :
Q1 : (It shows the starting time of the valid budget.If a user has multiple rows in this table, it means his/her budget has been updated with new amount)
id_user
budgete_start_date
budget_amount
1234
06-11-2021
120
1234
06-07-2022
200
56789
06-01-2022
1200
56789
06-07-2022
2000
643
05-05-2022
30
Q2 :(It shows the budget usage)
id_user
budgete_usage_date
amount_usage
1234
01-12-2021
50
1234
05-08-2022
100
56789
10-02-2022
60
56789
07-08-2022

I need to find a way to create the following view to know what was the valid budget at
budgete_usage_date.
id_user
budgete_usage_date
amount_usage
valid budget
1234
01-12-2021
50
120
1234
05-08-2022
100

56789
10-02-2022

1200
56789
07-08-2022
500
2000

How can I do that with calculated field in Tableau (with db made by relationship)?
If that's not possible, how can I do that directly in query? (changing the relationship to a single query)
