  Hello.

  I have a table (say orderlines) with orderrows,    There is a column that holds the "Year"  of the orderline.

  I like to write a  userdefine function that calculate how many years in a row that item has been sold from today and back.

   

  For examle :

  If I in the table have:

  ItemA    2020

  ItemA    2020

  ItemA  2019

  ItemA  2019

  ItemA  2019

  ItemA 2017

   

  The result is two year (since 2017 is not in a row)

   

  IF I have

  ItemB     2019

  ItemB     2019

  ItemB   2018

  ItemB   2018

   

  the result is 0  because it is not sold 2020

   

  How can I accomplish this?
