AX 2009 ATP Ignoring Purchase lead time

(0) ShareShare
ReportReport
Posted on by 145

I have a situation which results in incorrect confirmed delivery date on sales order. If there is an item which is only bought when there is a sales order and volumes are very low, the ATP time fence is 100 days, purchase lead time is 30 days, there is no stock on hand, no purchase order and no planned purchase order. In this situation, when a sales order is created, the confirmed delivery date is today + 100 days.

What do I need to setup so that confirmed delivery date is today + 30 days and the overnight run creates planned PO.

    Hi,

    Can you check the delivery date on the sales order line ? What value is  filled? Today, or another date? Is the 100 days here already?

    Hi, Andre

    The requested delivery date and requested ship date is today and confirmed delivery date and confirmed ship date is 100 days later.

    When I created sales header, I ticked "Confirm dates" tick box so that while creating order lines over the phone with customer, Order processing can suggest delivery dates.

    Kind Regards

    ATP is what is available to promise. You will not in the AR Parameters you can include planned orders as well, but the logic is to look for the stock you have and the commitments you have with vendors whether they are planned or firm depending upon the flag. In your scenario you have no stock and you have no planned or firm orders in the time fence and therefore the amount that is "Available" for you to promise is 0 so it puts the lead to to the time fence of ATP and says 100 days.

    What you are looking for is for the system to look 100 days and if it finds nothing to then suggest the commitment of 30 days based upon the lead time. This is "Capable" to Promise or CTP where the calculation looks in a similar manner to what is available and if not calculates when you are capable of supplying, which in this example would be 30 days. Look at the CTP option on the order you are playing with and hopefully it will give you what you want.

    Hi

    I am aware of CTP functionality in AX 2012. Is there anything in AX2009 which works like CTP.

    Apologies forgot about AX2009. I would say no but it was a long time ago now and I do not have easy access to the system, it was probably one of the reasons they expanded the limitations of the delivery date control in AX2009. If the delivery date control is sales lead time, ATP and None then that is your answer - it does not exist in AX2009.

    Hi

    I think that was our conclusion. The workaround we are going to implement is by setting item specific ATP to be equal to purchase lead time. That way, the maximum AX will add to confirmed delivery date is purchase lead time. There are some implications of these settings on master planning. For example, If positive days set in coverage group is less than ATP days setup for the item, then Master planning ignores on hand stock when raising a planned order. But we can setup positive days for coverage group to be equal to coverage time fence.

    Thanks you for your help.

    Regards
