## Calculating delta of product Quantity between two dynamically selected dates

I am trying to calculate the delta of product quantity for two dynamically selected dates. I have a table populating the beginning, ending and the delta inventory for both the dates. Now I am having trouble calculating the delta between DI2-DI1 as shown in the image. The date selection is dynamic and User selected. The sample data and the .pbix files are uploaded to Goggle Drive. Any help is appreciated.

Here are the steps you can follow：

1. Create calculated table.

``Table = SUMMARIZE('Inventory Changes','Inventory Changes'[as_of_date])``

Result: 2. Replace the second slicer with [as_of_date] of the newly created table 3. Select the slicer above, select Edit interactions of Format, and select the Filter flags in both tables 4. Create measure.

``````_begin =
SUMX(FILTER(ALL('Inventory Changes'),[as_of_date] in SELECTCOLUMNS('Table',"1",[as_of_date])&&[product_identifier1]=MAX([product_identifier1])),[opening_inv])``````
``````_end =
SUMX(FILTER(ALL('Inventory Changes'),[as_of_date] in SELECTCOLUMNS('Table',"1",[as_of_date])&&[product_identifier1]=MAX([product_identifier1])),[closing_inv])``````
``````Delta_Inventory1 =
[_end]-[_begin]``````
``````Delta_Inventory2 =
SUM('Inventory Changes'[Delta_Inventory])-[Delta_Inventory1]``````
