Return the context value, in a new column of measure

[PietroFarias]

My question is for a question focused on a didactic example. I retrieved the table below with the measurement shown below. I am using Dax Studio for this example.

EVALUATE
ADDCOLUMNS (
    SUMMARIZE (
        CALCULATETABLE ( fSales, KEEPFILTERS ( dCompany[ID] = 5 ) ),
        [groupProduct],
        "totalSales", [totalSalesInPeriod]
    ),
    "totalSales_v1", [totalSalesInPeriod]
)

The totalSales column returned with the correct values for each group. The totalSales_v2 column returned without any filter.

My question is:
What would be the best practice to return in the column totalSales_V2 equal to the column totalSales? And why the filter context of the groupProduct is not applied in this column?

And the other question is, is the use of KEEPFILTERS in the example, a good practice or would using FILTER be better?

Well, what should have happened is that in the SUMMARIZE it should be for the group and the company ID while in the second, it should just be the group without the company id. You would need to implement the filter for the second one to have both the same. And I would just use FILTER and not KEEPFILTER that seems way more intuitive to me. But, that's just one opinion.
