how do I import indicies with excelimport.xem???

Hi all,

i have the following exceltable:

And the following importdefinition:

Table Indexdefinitionen=Table.Index.IndexColumn: Indexnumber=Comment, Indexname=<Parent>, Field=Column, Aufsteigend=Ascending

The 3 indexes are created, but not the indexcolumns, i tried both versions of fieldnames with tablename and without, i also switched on and of the option "create object if not exists", but no results, do i try to bind the field to the wrong object/collection within Table.IndexColumn?

Thanks for any advice
