Power BI Sum cells grouped by same ID

问题

How can I make a formula which sums all the cells which have the same ID?

Edit: Both of these columns are in the same table. I need a new column which calculates the sum of all the hours with the same ID.

回答1:

In that case, I would create a new summery table:

SummeryTable = 
SUMMARIZE(
    'TableName';
    'TableName'[ID];
    "Time_summed"; SUM('TableName'[TimeColumn])
)

Then you will end up with a table with distinct [ID] on each row and the sum of all hours corresponding to this ID from the original data table. Which you can use to create a relationship with the original table.

EDIT_1:

Yes you can if you use a calculated column like this:

SumTime = 
VAR thisID = [ID]
RETURN
CALCULATE(
    SUM('TableName'[TimeColumn]);
    ALL('Tablename');
    'TableName'[ID] = thisID
)
