Hello Everybody,

I’m trying to import all of my Assets Maintenance & Asset Maintenance log but the import tools show this error:

Row No 21: Error for row “***K-01” Error: Value missing for Asset Maintenance Log: Maintenance Status

frappe.exceptions.MandatoryError: [Asset Maintenance Log, ***K-01-2020-9]: maintenance_status

my excel import file:

The row 21 “Maintenance Status” is completed :’(

Can anyone help me?
