Cummulative sum with reference date in another table

Hi, cferraz_hemav 

Based on your description, I created data to reproduce your scenario. The pbix file is attached in the end.

Table1:

Table2:

There is no relationship between two tables. You may create a measure or a calculated column as below.

Measure:

Accumulated Measure = 
var _fieldid = SELECTEDVALUE(Table2[field_id])
var _infodate = SELECTEDVALUE(Table2[info_date])
var _startdate =
LOOKUPVALUE(Table1[start_date],Table1[field_id],_fieldid)
var result =
CALCULATE(
    SUM(Table2[data]),
    FILTER(
        ALL(Table2),
        Table2[field_id]=_fieldid&&
        Table2[info_date]>=_startdate&&
        Table2[info_date]<=_infodate
    )
)
return
IF(
    ISBLANK(result),
    0,
    result
)

Calculated column:

Accumulated Column = 
var _fieldid = Table2[field_id]
var _infodate = Table2[info_date]
var _startdate =
LOOKUPVALUE(Table1[start_date],Table1[field_id],_fieldid)
var result =
CALCULATE(
    SUM(Table2[data]),
    FILTER(
        ALL(Table2),
        Table2[field_id]=_fieldid&&
        Table2[info_date]>=_startdate&&
        Table2[info_date]<=_infodate
    )
)
return
IF(
    ISBLANK(result),
    0,
    result
)

Result:
