Warehouse Management - Clear Negative Stock from 902 Stype

[Eddie88]

Hi Experts,

I would like to request your assistance and guidance regarding an issue we are facing with negative stock appearing in storage type 902 due to a user error.

Scenario Overview:

1. A Purchase Order was created with line item 10 (Material ABCX) and a PO quantity of 10.
2. An inbound delivery was created, and the PGR was posted successfully. In the PO history, the 101 movement type with the material document is completed.
3. The issue occurred when a second inbound delivery was mistakenly created and received with a quantity of 20, resulting in an additional 101 movement.
4. Upon realizing the error, the user attempted to reverse the second material document, which posted a 102 movement.
5. After this reversal, negative stock remains in storage type 902 under both “Stock for Putaway” and “Pick Quantity” columns. Please refer to the attachment.

Additional Notes:

The Purchase Order has no remaining open quantity to receive (Still to be Delivered = 0).  I checked LB13 and LT24 and found no open transfer orders or documents that can be processed.

At this point, I am looking for guidance on how to clear or flush out the negative stock from storage type 902 caused by this human error. I would greatly appreciate any advice, recommended steps, or corrective actions.

Thank you in advance for your support.

The -20 on your 902 line indicates that there is still a quantity to be processed.

I’m not familiar with the configuration of your internal WM system, but generally, when you reverse a 101 movement, the system generates a 102 movement, as you mentioned. This also creates a transfer request, which is then followed by a transfer order. This step can be either automatic or manual, depending on your system setup.
When you confirm the transfer order, a quantity of 20 will be posted to your 902 line. In your case, the 20 entered against the -20 would bring the line to zero. To do this, there must be a positive quantity of 20 of that material somewhere in your bin location.

However, in your screenshot, I only see the -20 on the 902 line. Where is the corresponding 20 from the second inbound delivery?
