Count of Rooms Let based on DateArrive and DateDepart

[KAZ]

Hi,

I am trying to get rooms let figure for all room night bookings within a particular Month.

My data source is SQL.

I have a table with DateArrive and DateDepart.

e.g Data

DateArrive   DateDepart    NoOfNights

01/10/2022  03/10/2022   2

28/09/2022  04/10/2022   6

31/10/2022  11/11/2022  11

31/10/2022  31/10/2022  0

I am looking at October room nights and a guest arrives in September I am only after the nights the guest is staying in October i.e if a guests arrives in September from the above example I need to only include the 3 nights they are staying in October.  The same goes if the guest is arrivng in October and departing in November. Also note if a guest arrives after night audit the noOfNights is 0. This has to be treated as 1.

Hi @KAZ ,

I created a sample pbix file(see attachment) for you, please check whether that is what you want. You can create a measure as below:

Measure = 
VAR _mindate =
    DATE ( 2022, 10, 1 )
VAR _maxdate =
    DATE ( 2022, 10, 31 )
VAR _ardate =
    SELECTEDVALUE ( 'Table'[DateArrive] )
VAR _deptdate =
    SELECTEDVALUE ( 'Table'[DateDepart] )
RETURN
    SWITCH (
        TRUE (),
        _deptdate < _mindate
            || _ardate > _maxdate, BLANK (),
        _ardate >= _mindate
            && _deptdate <= _maxdate
            && _ardate = _deptdate, 1,
        DATEDIFF (
            IF ( _ardate > _mindate, _ardate, _mindate ),
            IF ( _deptdate >= _maxdate, _maxdate, _deptdate ),
            DAY
        )
    )

If the above one can't help you get the desired result, please provide some sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.

Also note if a guest arrives after night audit the noOfNights is 0. This has to be treated as 1.

There will be ambiguity if they arrive late (after midnight) but then stay for more than one night.  How are you planning to handle that?  Ideally you would have an additional column indicating late arrival.
