Sales Order has multiple confirmed schedule lines

[Former Member]

I am hoping this is going to be a quick one to answer, a sales order is created with Material A, order quantity 1. There is no stock at the plant so a Purchase Order is created for quantity 1, the confirmed quantity on the schedule line is set to 1, delivery date is in the future.

Then something happens & 2 new schedule lines are created all with confirmed quantities of 1, so we now have 3 schedule lines :

1 - Confirmed quantity = 1, referenced to Purchase Order & Purchase order item, delivery date "today"

2 - Confirmed quantity = 1, appears to be a copy of schedule line 1, with no purchase order item referenced, delivery date in the future

3 - Confirmed quantity = 1, no reference to a Purchase Order, stock coming from the plant, delivery date in the future

The Order quantity is now showing as 3 when it should be 1.

Can anyone advise why we have 3 schedule lines - all showing confirmed quantities ? Why does the order quantity now show 3 ?

Are there any ATP / MRP settings that I need to check ?

You should read the following SAP notes and check if they apply to your situation:

207942    MRP: Problems with requirements from sales order/de

149428    Double purchase requisitions by requirements

63704      Duplicated purchase order for sales order

Thank you for the SAP notes, but have found what is causing the multiple confirmed schedule lines. If the schedule line initially has a PR (and PO) against it but then our users decide to take the stock locally (they do this via a custom screen), then it adds a second schedule line - with a confirmed quantity. We then have 2 confirmed schedule lines.

I need to investigate our custom screen & how it works / confirm the correct procedure with the business in the particular scenario.
