Filter a lookup field based on another list columns

hi guys,

 

my 2 lists used for my app are :

Reservation { Name, Registration Number(LookUp Field), Destination }

Vehicules { Registration Number, Brand, Status(availability) }

 

i want to filter the displayed choices of the registration number lookUp field based on the availability of the vehicule (the status field),

is it possible to do this ?

and if so what should i do ?

 

thank you in advance.

Hi medBrami,

 

Can you take some screenshots of the controls and their formulas?

You can also break the formula up to see which parts work and which don't separately, before stringing it all together - so;

 

use this on the Items: property of a dropdown;

Filter(Vehicules, Status="Available").RegistrationNumber

or just 

Filter(Vehicules, Status="Available")

and set the Field: property of the dropdown control to RegistrationNumber

 

If this returns the expected result, then move onto the next piece and so forth.  Test each piece separately and perhaps we can find where it's breaking down.

You can also post some screenshots that show the controls and formula's and perhaps any errors and we can try resolve from there.

 

 

Kind regards,

Hi medBrahmi,

 

By the looks of it, the common key between the two lists is the registration number.

You could do this by filtering the Choices/DropDown control in the Reservation form.

 

So on the Reservation form datacard for RegistrationNumber, set the Items: property of the dropdown/choice control to;

 

Filter(Choices(Reservation.RegistrationNumber), Value in Filter(Vehicules, Status="Available").RegistrationNumber)

This will filter the available options down to those that have an "Available" status in the Vehicules list.  Just be aware that if you have more than 500 reservations you may run into delegation issues.

 

Hope this helps,
