Ok, let's contemplate the next scenario with powerapps:
We have a simple filter:
Filter(datasource, column1 = "condition")
After that you can refer a column like that:
Filter(datasource, column1 = "condition").Column2
But I realized that can't refer to a lookup column:
Filter(datasource, column1 = "condition").Column2.Value
So I can't do thigs like that:
Filter(datasource2, columnX in Filter(datasource1, column1="condition").Column2.Value
(column2 is a lookup column)
How could I filter a column using a "list" extracted from a filter with a lookup column? (as above)
Hope have explained well, thanks!
