Hello @Guilherme_Zambonato
Thanks for posting your question!
The solution you are looking for can be achieved by using JavaScript code. Please follow this Community post to import a new field, “Workdays in Status by months”
When you update your eazyBI advanced settings with the code in the Community post I shared, please select a new field, “Workdays in status by months,” for import and use it in your report similarly to the screenshot below. Note that the code will only work at the month level.
Best wishes,
Elita from support@eazybi.com
