One or more configuration keys are disabled in the data entity in D365 AX

Hello expertise,

I have  deployed a new sandbox environment for D365 Finance & Operations with update 15. and trying to import data like chart of accounts , customers , vendors .

But when import the record by using entity , its generating below error for all entity .

"One or more configuration keys are disabled in the data entity , 'Main account'. A field is available to be used in data management if the configuration key of the field, its table and its data entity are all enabled"

Please suggest how to solve this issue.

Thanks.
