Hello everyone,
How can I fix this error:
Expression.Error: We cannot apply operator - to types Date and Number.
Details:
Operator=-
Left=20/04/2022
Right=1
I'd like to substract 1 from the date.
Thank you
Hi @FranckGbadamass ,
You might wanna consider this M Power Query:
Date.AddDays ( [Merged.1], -1 )
Does this help?

Hi @FranckGbadamass ,
I may have reproduced your wrong scenario.
You should use Date.ToText() and Number.ToText().
Best Regards,
Stephen Tao
