How to prevent a new record sequence number to be created for a period of 14 days

Question

ALTER proc [dbo].[spCreateSequenceContainerFill]
(@containerID as nvarchar(64),
@lotNum as bigint,
@customerID as int = 1164,
@productID as int,
@fillDateTime as datetime
as
BEGIN
declare @checkcontainerID as bigint
DECLARE @ID int;
set nocount on
SELECT @checkcontainerID = CONVERT(bigint, SUBSTRING(@containerID, 1, 6)) FROM ContainerFillHistory WHERE containerID = @containerID
IF (@checkcontainerID is null)
SELECT @ID = COALESCE((SELECT MAX(ID) + 1 FROM ContainerFillHistory), 1)
ELSE
SELECT @ID = Max(ID) FROM ContainerFillHistory WHERE containerID = @containerID AND @fillDateTime >= DATEADD(DAY, 14, CAST(fillDateTime as DATETIME))
IF (@ID is not null)
SET @ID = @ID + 1
INSERT INTO ContainerFillHistory(ID, containerID, lotID, customerID, productID, fillDateTime, purchorderNum)
VALUES(@ID, @containerID, @lotNum, @customerID, @productID, @fillDateTime, null)
END
If there is a no record with an ID then a new record is created and inserted in the table.  After 14 days it is OK to add another record with that ID and bump up the sequence number of the total records in the table.  Handling the non existing
case the first time is OK, but the restriction of 14 days if a new record is trying to be inserted has to be ignored.
So far I have this TSQL code.

Please try the following and tweak accordingly.
ALTER proc [dbo].[spCreateSequenceContainerFill]
(@containerID as nvarchar(64),
@lotNum as bigint,
@customerID as int = 1164,
@productID as int,
@fillDateTime as datetime
AS
BEGIN
SET NOCOUNT ON;
DECLARE @ID int;
IF EXISTS (select * FROM ContainerFillHistory WHERE containerID = @containerID)
BEGIN
SELECT @fillDateTime = DATEADD(DAY, -14, @fillDateTime)
IF EXISTS ( SELECT *
FROM ContainerFillHistory
WHERE containerID = @containerID
AND CAST(fillDateTime as DATETIME) > @fillDateTime --AND @fillDateTime >= DATEADD(DAY, 14, CAST(fillDateTime as DATETIME))
BEGIN
RETURN; --//14 Days condition not met
END
ELSE
BEGIN
SELECT @ID = Max(ID) FROM ContainerFillHistory
WHERE containerID = @containerID
AND CAST(fillDateTime as DATETIME) <= @fillDateTime
END
END
ELSE
BEGIN
SELECT @ID = MAX(ID) FROM ContainerFillHistory ;
END
IF @ID IS NULL
BEGIN
SET @ID = 1 ;
END
ELSE
BEGIN
SET @ID = @ID + 1 ;
END
INSERT INTO ContainerFillHistory(ID, containerID, lotID, customerID, productID, fillDateTime, purchorderNum)
VALUES(@ID, @containerID, @lotNum, @customerID, @productID, @fillDateTime, null) ;
END
