Hi Sam and guys.

I would like your help to solve a problem that I´m facing on my modeling approach

A same “contract” could change its values acording some considerations. So I have an specific data with valid values between an initial date and an end date.

I´d like to build a table where I could bring for any date the valid data in this specific date, so that I could apply all the time inteligence paterns and treat my model as an static one.

What I´ve already done:

I construct a sample model with two date tables and I can select the values filtering in different periods through 2 date slices.once for each table.

```
Margem =
SUMX(Contratos;IF(Contratos[Movimentacao]="Compra";
-(Contratos[P]*Contratos[Q]);Contratos[P]*Contratos[Q]))
PnL_Data_Filter_Ini =
VAR vData = MAX('Calendar_Ini'[Date])
RETURN
CALCULATE([Margem];FILTER(Contratos;Contratos[DfimVig]>=vData && Contratos[DiniVig]<=vData))
PnL_Data_Filter_Fim =
VAR vData = MAX('Calendar_Fim'[Date])
RETURN
CALCULATE([Margem];FILTER(Contratos;Contratos[DfimVig]>=vData && Contratos[DiniVig]<=vData))
```

`Pnl Delta = [PnL_Data_Filter_Fim]-[PnL_Data_Filter_Ini]`

so I can calculate the results for different dates and compare them.

my problem is that as I need use an waterfall chart to explain the changes through time I would like to build an unique table where I can bring the valid data in each date.

So for this I imagine that I have to put in one table the valid values and consider just one date table.

How can I construct a table with this logic ?

Is my approach feasible?

Thanks in advance!
