Anyone knows what is [@Filter] and disambiguate same name columns of a filtered result

each time I start typing Filter while coding in PowerApps, intellisense proposes as a first choice [@Filter].

does anyone know what is this for?

 

it would be amazing that this could disambiguate a filtered result like:

 

AddColumns(Filter(Collection, Field1="matched"), "NewColumn", lookup(table, table[@field2]= ???[field2], field3))

 

unfortunately [@Filter][@field2] doesn't do the trick...  so I have to renamecolumns one of these same named fields in order to avoid ambiguity and get what I want.

Here's an example of how to correctly apply the syntax.  I assume what you are trying to do here is join matching results from the datasource called table and show the value for Field3 in NewColumn.

AddColumns(
    Filter(Collection, Field1="matched") As your_other_table,
    "NewColumn", 
    Lookup(table, Field2 = your_other_table[@Field2], Field3)
)

 

If this idea does not work for you please share some sample data as well as how the desired result looks.

@SergiP ,

I cannot test this presently, but you can use As for the disambiguation.

AddColumns(
   Filter(
      Collection,
      Field1="matched"
   ) As Matched, 
   "NewColumn", 
   LookUp(
      table,
      field2= Matched.field2,
      field3
   )
)
