Hi there.
I need to create a specific datetime to put in a sharepoint datetime field.
I have 2 datetime fields: one is with datetime, one is empty. I start from this situation, format is dd/MM/yyyy hh:mm :

I set a get item() function to take this specific element from my list.
I create a variable to set the time:

Then, I need to extract the date from the first field and concatenate it with the variable contains the time, and I use a compose:
the expression used to extract the date is
formatDateTime(items('Applica_a_ogni')?['Inizio'], 'dd/MM/yyyy')

The output seems correct:

then why in my list appear this?

some hints?
Thanks.
