Due date falls on 80 days from base line date ........but end of that month

Question

Hi All
Can any one please guide me in creating a payment term
The Base Line Date would be 80 days from Posting date ........... But end of that month
Example
Posting date 01.01.2009 so the base line date would be on 21st March
01.01 ;          31.01 ;                            31 Days
01.02 ;          28.02 ;                            28 Days
01.03 ;          21.03 ;                            21 Days               80 Days              
But due date should fall on end of that month 31st of march
So irrespective of any day calculated as above in that month  it will always take the baseline date as last day of the month    
Its Picking up the posting day as Baseline date from Transaction VA01 -> Additional data tab -> ETD ( Festinated Time of Departure)
From this date it need to calculate the due date as above ( 80 day but last day of the month)
Please Guide
Many thanks in advance

Hi Aditya,
You may have to create 2 payment terms using the day limit option to meet this requirement.
Follows the below steps -
T-code OBB8
Term 1
Payment terms = xxxx (as you wish)
Day limit = any number between 10-15 (you may fix an appropriate date as you think fit for your business)
Default for baseline date = Posting date
Payment terms/fixed date = 31
Payment terms/additional months = 2
Term 2
Payment terms = same name as above
Day limit = 31
Default for baseline date = Posting date
Payment terms/fixed date = 31
Payment terms/additional months = 3
Logic here is... for all invoices with posting date on or before 10th-15th of a month, 80th day will fall definitely on the 2nd month. Invoices with posting date after 15th, the 80th day will fall on the 3rd month.
You have to take a concious decision on the day limit number. Because 80 days will not exactly work for all the months.
