System.Data.Entity.DbUpdateException

{System.Data.Entity.DbUpdateException: An error occurred while saving entities that do not expose foreign key properties for their relationships. The EntityEntries property will return null because a single entity cannot be identified as the source of the exception. Handling of exceptions while saving can be made easier by exposing foreign key properties in your entity types. See the InnerException for details. ---> System.Data.UpdateException: An error occurred while updating the entries. See the inner exception for details. ---> System.ArgumentException: Parameter value '12.50000' is out of range.

Got above error while performing database.save() of Entity Model .

The reason for failure was the decimal field in DB which was set for DECIMAL(6,5) whereas the value trying to be saved was 12.00000 .

This is how it works :

e.g.
decimal of (4,1) can hold upto 999.9
decimal of (3,1) can hold upto 99.9
