calculate percentage based on dates met

hello folks,

I am wondering if anyone could offer some help in a calculation based on two dates.

I have a date field called: requested delivery date, and another date called: Actual Delivered Date

I need to compare them and calculate the % based on how close, or far the Actual Delivered Date (when product actually arrived to customer) is from the Requested Delivery Date (requested by the customer).

Give us some sample data + expected output of what you're trying to pull off here.

here is some data attached.

if order was delivered on the requested delivery date it means work_completed 100%

if
then in item was not delivered on the date show percentage of how close or far from the requested delivery date, 70 % or 80% or 90% an so on....

I tried this:

(DATEDIFF(DAY, [RequestedDeliveryDate], [ActualDeliveryDate]) / CAST(365 AS FLOAT)) * 100

Open in new window

But for rows with dates like:

Requested Delivery Date
2013-04-23 00:00:00.000

Actual Delivery Date
2013-04-21 00:00:00.000

I get:
-0.547945205479452

Another one is

Requested Delivery Date
2013-06-26 00:00:00.000

Actual Delivery Date
2013-04-28 00:00:00.000

It gives me:
-0.161643835616438360

But it should be positive because it was delivered way before the Requested Delivery Date

And when the actual delivery date equals the requested delivery date, I get 0%, but is should be 100%

try this.

;WITH CTE AS (SELECT *,DATEDIFF(DD,RequestedDeliveryDate,ActualDeliveryDate) Diff
                FROM Test),
     CTE1 AS (SELECT *,
					 MAX(Diff) OVER (PARTITION BY 1) Max_Diff,
					 MIN(Diff) OVER (PARTITION BY 1) Min_Diff
				FROM CTE)
SELECT ItemNumber,RequestedDeliveryDate,ActualDeliveryDate,
       ROUND((1-(Diff*1.0/CASE WHEN Diff < 0 THEN Min_Diff ELSE Max_Diff END))*100,0) Close_Far
  FROM CTE1

is there a way to do this in an already existing query? I am not sure how to add your example to my stored procedure query

It is not working for me because that select is the select of an insert into to populate a variable table in my stored procedure.

so the part:

      INSERT INTO @SalesOrderLeadTime
      (
            [ChainName]
      ,      [OrderNumber]
      ,      [ItemNumber]
      ,      [ItemDescription]
      ,      [OrderDate]
      ,      [RequestedDeliveryDate]
      ,      [PromisedDeliveryDate]
      ,      [PostingDate]
      ,      [ActualDeliveryDate]
      ,      [ReqDeliveryDateMet%]
      ,      [QuantityOrdered]
      ,      [QuantityDelivered]
      ,      [LeadTime_NumberOfDays]
      )
WITH Original_CTE <<< this does not work
