How to build the a sum with differnet start dates?

Hello,

i have my articles with the date of the last inventory. I want to determine the number of the products that I have bought since the last inventory up to a certain date .

For example: For the Product Tee: From the inventory date 1.1.2016 up to 31.1.2016

= 30 units

(Date dd,mm,yyyyy)

DateUnits
31.12.201510
07.01.201615
01.02.201615
05.02.201620
10.02.201615

How can I solve this in one table?

Many thx

best regards

Christoph

May be this:

=Sum(If(Datum >= [Inventory Date] and Datum <= vDate, Units))

Where vDate comes from user input

Alternatively if you have a unique combination of each row, you can also use Set analysis:

LET vDate = '1.1.2016';

Inventory:

LOAD * INLINE [

    ID, Article , Inventory Date

    1, Tee, 01.01.2016

    2, Milch, 20.12.2015

    3, Zucker, 24.12.2015

    4, Brot,  01.01.2016

];

Purchase:

LOAD *,

  RowNo() as Key;

LOAD * INLINE [

    ID, Units, Datum

    1,10,31.12.2015

    1, 15, 07.01.2016

    2, 15, 07.12.2015

  1, 15, 10.02.2016

  1, 15, 01.02.2016

  1, 20, 05.02.2016

  2, 5, 22.12.2015

  2, 10, 15.01.2016

  2, 4, 05.02.2016

  3,10,31.12.2015

    3, 15, 07.01.2016

    3, 15, 07.12.2015

  4, 15, 10.02.2016

  4, 15, 01.02.2016

  4, 20, 07.03.2016

  4, 5, 22.12.2015

  4, 10, 19.01.2016

  4, 4, 06.02.2016

];


I created Key which is Unique for each ID and Datum. Now I can use this in my set analysis like this:

=Sum({<Key = {"=Datum >= [Inventory Date] and Datum <= vDate"}>} Units)
