Filter collection by values of another collection.

I have two, single column tables from two different sources that I'd like to compare and filter the first table based on whether the values are present in any record of the second table in the different source collection. Example:

Table1
----------
Value1
Value2
Value4
Value5

 

Table2
---------
Value2
Value3
Value5


I would then like Table1 to be filtered to look like

Table1
--------
Value2
Value5


I'm trying to avoid creating a new table in this scenario, which has complicated things a bit. I specifically need to filter the original table, since I'm trying to filter the default items of a combobox and it seems to be very particular about the Items table being the same source as the DefaultSelectedItems table.

Hi @AdamD 

 

you can try using the below expression:
Filter(Table1,Column1 in Table2.Column2).Column1
Here Table1 is my first table and Column1 is the name of its column, Same for Table2, it has a column named Column2.
 
The result will be the values from table1 that exist in Table 2MicrosoftTeams-image (90).png

 

Hope this Helps!

This thread helps me to get the formula to not insert a record in the collection if it's already exist.  1. Clear and Collect in Collection ClearCollect( Collection1, AzureAD.GetGroupMembers("AzureADGroupObjectID#1").value ); 2. Collect and Do not Collect a record if existing in the collection  Collect( Collection1, (Filter(AzureAD.GetGroupMembers("AzureADGroupObjectID#2").value, Not(mail in Collection1.mail))) ); I hope this helps someone looking the same scenario I have. 🙂

I used this formula to filter a data table from a lookup table. I put this in the OnVisible of the screen:

 

ClearCollect(colQuestionsList,(Filter(CCAQuestions, QGroupKey in Filter(CCAChartQGroup, ChartKey = varRecord.ChartKey).QGroupKey)))

 

I then put 

Filter(colQuestionsList, QGroupKey = varQGroupRecord.QGroupKey)

in the Items property of the gallery, where varQGroupRecord is set by the user through another gallery on the same screen.

That gallery's Items is set to :

Filter(CCAChartQGroup, ChartKey = varRecord.ChartKey)

Works beautifully!
