Weighted Measure

Hello to all,

I am trying to do some dashboards for Logistics departmento and I am having trouble calculating a weighted measure.

I have the calculated columnes "Lead Time" and "Dif Date".

Lead Time : Days between date create and date receipt

Dif Date : Days between date delivery and date receipt

Sample data: 



What I want to do is to weight this two measures by the quantity receipt.

What I have done is exporting the data by provider and week to another table: 

Provider & Week Level (Table) = 
ADDCOLUMNS(
	ALL( Table1[Provider] ; WEEKNUM ( Table1[date receipt] );
	" Total received Quantity " ; Table1[received quantity]
)

and importing that data back into the original table. This way I can divide the "Quantity Receipt" by the "total" from that provider and week.

For Weighted (column) =
DIVIDE(
	Table1[received Quantity] ; RELATED( 'Provider & Week Level'[ Total received Quantity ] )
)

Weighted Lead Time =
IF(
	HASONEFILTER(  Table1[Provider] );
	SUMX( Table1 ; [Lead Time (column)]*[For Weighted (column)] );
	BLANK()
)

This is not a really nice way to do it... but it is the only way I have found to do it.

The bad thing about this is that I can only view the weighted Lead time and Dif Date by provider and week, otherwise the measure is wrong.

"For Weighted (column)" has to be a measure that gives me the total of quantity receipt based on the filter applied on the slicers in the report.

E.G.: I would like to see the weighted lead time of the family 2 or store 3. The end user has to be able to play with all the slicers.

I hope you can help me...
