Power View using Tabular Model (Numeric data)

Hi all,

I've 2 tables as following which I imported into a tabular model.

Here's the data. Both these tables are joined using column "Main_No"

Table 1

Main_No           Name       

1                        TRAN001

2                        TRAN002

3                        TRAN003

Table 2

Detail_No         Detail_Name        Main_No        Amount

1                       D0001                   1                     200.00

2                       D0002                   2                     100.00

3                       D0003                   1                       50.00

4                       D0004                   3                     100.00

When I go to Power View and dragged the following columns into the report view.

Name, Amount

The output came as following which is incorrect. I've selected the option "Sum" under the column Amount in Power View.

Name             Amount

TRAN001          450.00

TRAN002          450.00

TRAN003          450.00

The output came as following (which is incorrect as well ). I've selected the option "Do not Summarize" under the column Amount in Power View.

Name             Amount

TRAN001          200.00

TRAN002          100.00

TRAN001            50.00

TRAN003          100.00

What should I do to get the proper aggregation as following.

Name             Amount

TRAN001          250.00

TRAN002          100.00

TRAN003          100.00

Any help would be much appreciated.

Thanks
