When an user tries to create an asset in SM the error message is appearing:
Error Number: -2147216903
Error Description: NM3 FlexAttrGrid Error
Invalid Property value
Refresh Record Line :204
The error appears when there is either a duplicate value or duplicate sequence in the same Asset Domain.
Open NM0301 Asset Domain form and find the duplicated sequences and then end date one of them, leave only one available. Save changes.
