Hello @v-bofeng-msft ,
Thank you for answering.
I tried doing your solution,
Collect(existingCollName, ShowColumns(Filter('SP List','ID No.' = _itemSelected.'ID No.'), "Col1","Col2","Col3", "Col4", "Col5")));
But I got this error, "The collect cant contain values of this type."
This is what I did if I only have to get 1 item with the selected ID, but I don't really know how to collect the other items.
Collect(
existingColName,
{
Col1: _itemSelected.Col1,
Col2: _itemSelected.Col2,
Col3: {Value: _itemSelected.Col3},
Col4: _itemSelected.Col4,,
Col5: {Value: Int(_itemSelected.Col5)}
}
)
