Overconfirmation-Sum of confirmed quantity exceeds sum of stock

[murat_mrdn]

Hi,

We have stock for a material but on the CO06 screen cumulated ATP quantity is negative. Although there is only one open sales order.

How can I correct the problem. Thanks.

Hello Murat

Negative ATP is a serious condition which might have happened because of a) wrong settings in the scope of check- Example Sales requirements being included in the scope for Deliveries (OVZ9) , b) business transactions (e.g. Purchase Orders) getting postponed/canceled, and/or, c) bad user practices like frequent manual intervention to unconfirm one order (MRP Element) to confirm another.

Please review the following OSS notes:

1) 547118 - FAQ: Result of ATP calculation- Question 4

2) 153355 - No availability owing to negative ATP quantity

3) 835219 - FAQ: ATP composite note

Hope this helps. Thanks.
