Cleaning dates issue

[GeekAlfPro]

Hi there,

i've a file, i need to clean.

in my samples data below, i have to keep the last date (Justif - Date fin absence) by people, but only if the column (Regroupement) is the same, and if the date date are in the same periode.

e.g. the first 4 lines should be one line because the dates follow each other (09-11-2020 to 07-12-2020)

inversely, for the last 3 lines, i should have 2 lines (02-11-2020 to 04-11-2020) and (18-11-2020 to 24-11-2020)

Yes, it´s aexactly the same as what was done in the thread I pointed to earlier. Place the following M code in a blank query to see the steps. The forst two steps are just to enter your sample data. #"Add Column" is the crucial step. It could be made into a function to make it more legible

let

Hi @AlB 

thanks a lot, the result is exactly what i need !

i wouldn't have found it on my own.

thanks again and have a good day

Hi @GeekAlfPro 

Can you share that table in an excel file? I cannot quite copy it correctly, with the aligned column names. And please include also a second table with the expected result.

You have to share the URL to the file hosted elsewhere: Dropbox, Onedrive... or just upload the file to a site like tinyupload.com (no sign-up required).

We recently solved something that is similar. Have a look:

Hello @AlB

You will find 2 tabs with the expected result !

thanks for your time
