Answer 1

If you must write to the identity column, use

SET IDENTITY_INSERT YourTableName ON

just as the error message suggests.

Otherwise, don't try to write to the identity column.

Answer 2

Your statement

insert into ENG_PREP

will try to insert values into all of the columns of your table - including the IDENTITY column, where you should never insert a specific value.

What you need to do is specify which columns of your table you really want to insert values into, and leave out the IDENTITY column - that'll be automatically handled by SQL Server itself:

 INSERT INTO dbo.ENG_PREP(column1, column2, ...., columnX)
 VALUES(values1, values2, ...., valuesX)

You only need to specify those columns that you really want to set a value for (e.g. you can probably skip most of those columns where you just insert a '' in your example).
