Pivottabel: Pivottabel sidste 4 uger -

For at oprette en pivottabel, der viser de sidste 4 ugers data (dvs. rullende 4 uger), kan du tilføje en hjælpekolonne til kildedataene for at markere poster i de sidste 4 uger og derefter bruge hjælpekolonnen til at filtrere dataene i drejetabellen. I det viste eksempel er den aktuelle dato den 25. august 2019, og pivottabellen viser 4 komplette forrige. Når nye data tilføjes over tid, fortsætter pivottabellen med at spore de foregående 4 uger baseret på den aktuelle dato.

Felter

I den viste pivottabel er der fire felter i kildedataene: Dato, Salg, Uge og Filter. Filter er en hjælpekolonne med en formel, der markerer de sidste 4 uger. Uge er en hjælpekolonne, der returnerer mandag for en given dato (kun for nemheds skyld). Salg er værdifeltet, og Uge er tilføjet som et rækkefelt til at gruppere efter uge:

Formel

Formlen, der anvendes i D5 (Uge), kopieret ned, er:

=B5-WEEKDAY(B5,3)

Denne formel returnerer mandag i ugen for en given dato.

Formlen, der anvendes i E5 (filter), kopieret ned, er:

=AND(B5>=TODAY()-WEEKDAY(TODAY(),3)-28,B5

This formula checks for dates in the last n weeks. It returns TRUE when a date is in the last 4 complete weeks, and FALSE if not. See the link for a full explanation.

Customizing week count

To customize the weeks displayed, adjust the Filter formula as needed to increase or decrease days. For example, to display the last 6 weeks (42 days), use:



=AND(B5>=TODAY()-WEEKDAY(TODAY(),3)-42,B5

Steps

  1. Add helper column for Week with the formula above
  2. Add helper column for Filter with the formula above
  3. Create a pivot table
  4. Add Sales as a Value field
  5. Add Week as a Row field
  6. Set number formatting for Week as desired
  7. Add helper column as a Filter, filter on TRUE
