How to fill the gaps in values between dates

[Anonymous]

1. Sorry for my English.

2. Here is the question.
I have gaps in dates, beacause rates set up not every day.

What i need is a measure that give me day to day values of rates.
for example:
Date-Rate
07/03/18 - 26.60
13/03/18 - 26.20
16/03/18 - 26.50
03/04/18 - 26.30

the goal is to have
07/03/18 - 26.60
08/03/18 - 26.60
09/03/18 - 26.60
10/03/18 - 26.60
11/03/18 - 26.60
12/03/18 - 26.60
13/03/18 - 26.20
14/03/18 - 26.20
etc.

I know that this is VERY easy task, but i cant handle it.

PBIX

3 tables.
2 dimention tables: DimCurrency (PK Guid), Calendar (PK Date)
1 fact table: FactCurrenciesRates (FK DimCurrency.Guid, FK Calendar.Date)

Thank you all in advance.
