Daily Rank Entries from Customers

[HMJSomerset]

I have a table where providers submit their capacity each day. Sometimes, if a new slot opens up they complete the form a second time to update their capacity. What I want to do is rank each entry for each provider each day.

e.g

Provider	Timestamp	Capacity	Rank
A	24/05/2021 10:18	1	1
A	24/05/2021 09:18	0	2
B	24/05/2021 10:20	0	1
A	23/03/2021 10:30	1	1
B	23/03/2021 09:20	2	1

Daily Rank =

RANKX(

FILTER(

ProvCapacity,

ProvCapacity[ProviderID]=EARLIER(ProvCapacity[ProviderID])

),

ProvCapacity[Timestamp]

)

With this formula, I get the correct rank for 24/05/2021 but 23/05/2021 is assigned a rank of 3.

How can I adjust the expression to reset the calculation for each day?

@HMJSomerset , Create a date from from Timestamp

Date = [Timestamp].date
or
Date = date(year([Timestamp]),month([Timestamp]),day([Timestamp]))

and then try this rank column

Daily Rank =
RANKX(
FILTER(
ProvCapacity,
ProvCapacity[ProviderID]=EARLIER(ProvCapacity[ProviderID]) && ProvCapacity[Date]=EARLIER(ProvCapacity[Date])
),
ProvCapacity[Timestamp]
)

Thank you.  I have amended the DAX and it now works correctly.
