Column 3 (Parent Cost Center) The following values do not exist for Cost Center

Hi there people .
I have been trying to upload a tree of cost centers
But for some reason that i cant figure out .
ERPNext keep giving me this error

Column 3 (Parent Cost Center)

The following values do not exist for Cost Center : (All the parent accounts in this column)

Google sheets link to the file

Please help.

You would have to upload parent cost centers first and then the child cost centers. If you do both simultaneously in a single upload you will get errors.

Yes . Thank you .
That exactly was the case .
If a parent is not there - the child in the same sheet will not be created.
So in a way, one single import can not create both parent and child cost center.
Thank for the help.
