ATP+ issue margin query

(0) ShareShare
ReportReport
Posted on by 330

Hi All

I am trying to setup ATP + issue margin and getting some strange results (I'm sure they're correct - I just don't understand how they are being worked out).

I have setup a simple stocked item that has no inventory.

I have pointed it to a coverage group that has an issue margin of 5 days. The coverage group is setup to use a standard calendar with working times Mon-Fri 9:00 to 17:00). The master planning parameters is set with 'Safety Margin In Day' to Working Days = ON

In my sales ledger parameters I have set the ATP time fence to 5.

I don't have any demand or due supply for the item.

I create a sales order (order date 6th Feb) and add the item line for my item and the requested ship date is changed to the 19th Feb - a lead time of 13 days. I'm a bit unsure how this is worked out but assume it is on the premise that 10 working days INCLUDING today (as I don't have a cutoff time) takes me to the 19th.

If I then change master planning parameters set 'Safety Margin In Days' = Working days = OFF I get the following...I can only assume that AX is counting forward 9 days from today's date and getting to the 15th - seeing that is a Saturday and therefore suggesting the 17th (the Monday) as the earliest?

Why is the lead time 11 days? 

Note that working days still suggests it is set to YES even though it is not.

Thanks in advance for any help.

    Hi Miller,

    The ATP calculation uses Calendar day even though you closed on the weekends.  But the issue margin can be calculated as calendar days or working days.

    For the first screenshot,

    February 6th (order date) + 5 days (ATP) + 2 days (weekend) + 5 days (safety margin) = February 18th

    So shipped on February 19th     Lead time = 19-6 = 13 days

    For the second, not considering working day

    February 6th + 5 days + 5 days = February 16th      Ships on February 17th

    For ATP calculation shipments, you can see this: organicax.com/.../

    Hi Miller,

    Do you mean show Sat/Sun in Available ship and receipt dates form(screenshot)? If so, you need to set Sat/Sun as Open in related calendar,such as shipping calendar.

    Hi

    Yes that's the form I'm referring to, I would like to show Sat/Sun even though they are NOT shipping dates (i.e. they should remain closed).

    Hi Miller,

    If so, the OOB function cannot achieve it.
