I have a dropdown where you can select your country. It's filled as follows:
Sort(Distinct(PurchaseOrderTable,Country_Column1), Ascending)
The PurchaseOrderTable is the table on the canvas. The Country column in that table is filled like this:
Sort(
Filter(
AddColumns(
PurchaseOrderHeadersV2,
"Country",
LookUp(
VendorsV3,
VendorAccountNumber = 'Vendor account'
).AddressCountryRegionId
),
(
IsBlank(TextPOSearch.Text) ||
(
TextPOSearch.Text in 'Purchase order' ||
TextPOSearch.Text in 'Vendor name' ||
TextPOSearch.Text in 'Vendor account'
)
) && Country = DropdownVendorsCountry_1.Selected.Result
),
'Purchase order',
Descending
)
Now there is this error on the dropdown: "Warning: The columns produced by this rule are all nested tables and/or records, however the property expects at least some columns of simple values"
How can I reference the Country column in the table, without having this error?
