Explicit value for the identity column in table error?

Question

I get the below error message, I have debugged both identity inserts and they execute with no problems. Has anyone had trouble with this error before and does anyone know how to fix this?

Msg 8101, Level 16, State 1, Line 1
An explicit value for the identity column in table 'c365online_script1.dbo.tProperty' can only be specified when a column list is used and IDENTITY_INSERT is ON.

Code:

declare @Source_Database_Name varchar(255) = 'Production2';
declare @Destination_Database_Name varchar(255) = 'c365online_script1';

declare @Company_Id int = 1 --declare a companyid 

CREATE TABLE #CompanyID (ID bigint)

INSERT INTO #CompanyID(ID)
    VALUES('15')

-- Copy over company records from tCompanytable

--FIRST CURSOR LOOP THROUGH THIS TABLE
CREATE TABLE #TableList (
    processorder int,
    tablename NVARCHAR(100)
    )
INSERT INTO #TableList (processorder, tablename )
VALUES
(1, 'tProperty');

DECLARE @Counter INT = 0  -- counting variable

-- company cursor

SELECT ID from #CompanyID;

open copyCompanyDataCursor

        SELECT processorder,tablename from #TableList order by processorder;

        open copyTableDataCursor

        while @@FETCH_STATUS = 0
        BEGIN

Well, the error says it all:

An explicit value for the identity column in table 'c365online_script1.dbo.tProperty' can only be specified when a column list is used and IDENTITY_INSERT is ON.

So your INSERT statement MUST use a column list!

Use

INSERT INTO dbo.Table(col1, col2, ...., colN) VALUES(Val1, val2, ...., ValN)

and not just

INSERT INTO dbo.Table   VALUES(Val1, val2, ...., ValN)
                     ^^^^  no column list defined!! 

then it'll work!
