powerapps filter?

[js86]

Hi,

maybe this is obvious, but i am new to powerapps. I have 2 tables:

1. Location table with just one column

Location

A

B

C

2. Transaction table

Transaction; Property; Location

Buy; House; C

Sale; Apartment; A

I want to create dropdown control, where i want to see the list of locations from table 1, which cannot be found in table 2, but there have to be condition that i will check only property "House".

Hope that makes sense

thank you

Jan

Set your items property on the dropdown to the following:

Filter(LocationTable,
           !(Location in Filter(TransactionTable, PropertyType="House").Location)

        ).Location

This will first filter the Transaction table based on only records with property types of "House" and will feed that filtered set of locations to the IN operator of the LocationTable filter.

Notice the ! operator.  This is the same as Not.  (since you mention you are new to PA, just mentioning it so you don't get confused)

So, in english this filter reads as follows:

FilterTheRecords of LocationTable if the Location is NOT in the Filtered records of the Transaction table where the property type is "House".

Pretty sure that's what you're looking for.

Enjoy
