Overdue calculate

Question

Hi Experts,
How to Caluculate the below overdue situation:
'For analysis priority for confirmed delivery date will be given as this confirmation is given by vendor.If confimation is not updated in PO then requested delivery date will be considered.If both exists then priority for confirmed delivery date will be given.Below is the logic
*Consider first date of "This week" from input.
*Search Purchase Orders for delivery dates from (first day of selected week - 365 days) to (first day of selected week - 1 day)
*First search purchase orders "EKES-EBELN" in EKES. To get Purchase Orders, select Delivery date "EKES-EINDT". "From date" is  (first day of selected week - 365 days) & "to date" is (first day of selected week - 1 day)
*Sort Purchase Orders for Vendor EKKO-LIFNR,Plant EKPO-WERKS from input,Storage Location EKPO-LGORT
*Count not delivered Qty for above sort criteria.
Not Delivered Qty= (Sum of EKES-MENGE)-(Sum of EKES-WEMNG)
*If Purchase Order history is blank in EKES,then select delivery date from EKET.Search purchase orders "EKET-EBELN" in EKET. To get Purchase Orders, select Delivery date "EKET-EINDT". "From date" is  (first day of selected week - 365 days) & "to date" is (first day of selected week - 1 day)
*Sort Purchase Orders for Vendor EKKO-LIFNR,Plant EKPO-WERKS from input,Storage Location EKPO-LGORT
*Count not delivered Qty for above sort criteria.
Not Delivered Qty= (Sum of EKET-MENGE)-(Sum of EKET-WEMNG)

Hello,
I do not know why are you doing this exercise in EXCEL, when SAP has provided ready-made solution for this?
Execute FBL5N - Open items
Change Layout (Ctrl+F8)
Select "Arrears after net due date".
Just for your information: Overdue date are the difference between the "Current Date" and "Net Due Date", but NOT "Document Date" and "Net Due Date".
Out of SAP Scope:
If you want to find out the number of days between two dates then
A1 = 31/10/2008
A2 = 29/12/2008
A3 = Formulae = DAYS360(A1,A2)
Please make sure that the values in cells A1 and A2 are in DD/MM/YYYY (valid date format)
Hope this will help you.
Thanks,
Ravi
