Filling gaps with last value available

I think I finally found a solution for my own problem.

Steps to solution:

1. Table is filtered at each line using as criteria the item, the date (it must be lower than the one in the actual line) and I remove all the BLANK lines in the value column
2. Now I have a table without BLANK values, for the given item and for all the dates lower than the one in the actual line
3. I get the max date of this table
4. I get the value of this max date using a SUMX applying once again another filter based on the max date found previously

test = 
VAR CurrentItem = Table[Item]
VAR CurrentDate = Table[Date]
VAR FilteredTable = FILTER(Table;Table[Item] = CurrentItem && Table[Date] < CurrentDate && Table[Value] <> BLANK())
VAR Last_Max_Date_Value = MAXX(FilteredTable;[Date])
VAR FilteredTable_MaxDate = FILTER(FilteredTable;[Date] = Last_Max_Date_Value)
VAR Value_For_Last_Max_Date_Value = SUMX(FilteredTable_MaxDate;[Value])
RETURN
    IF(
        ISBLANK(Table[Value]);
        Value_For_Last_Max_Date_Value;
        Table[Value]
    )

The final table just for item 1:
