Cannot post goods issue (PGI) or delete a delivery with assigned HU's

Issue

Cannot post goods issue (PGI) or delete a delivery after the serial number has been deassigned from Handling Unit (HU) when:

• Transfer orders in Warehouse Management (WM) have been confirmed
• HU already posted in WM to interim storage bin for goods issue Reproducing the Issue

1. Create outbound delivery (transaction VL01N / VL10)
2. Create transfer order to pick stock (LT03)
3. Confirm transfer order and HU's are updated to the outbound delivery (LT12)
4. Deassign the serial number from the HU (IE02)
5. Cannot goods issue / delete the delivery (VL02N)

Root Cause

• Serial number has been deassigned from the HU
• Transfer orders in WM have been fully confirmed

Solution

The storage unit / handling unit must be moved back to the source storage bin in order to reset the pick quantities on the delivery.
Depending on whether or not the storage location is HU managed, follow the relevant case below:

Non HU-managed storage location:

1. Transfer orders can be reversed using transaction LT0G
2. Confirm the new TO (LT12)
3. In the main delivery overview screen (VL02N), select the required item numbers, click on Edit, select "Copy Pack Quantities As Dlv. Quantities" & Save (Ctrl+S).
4. Delete the delivery or repick the delivery (based on your requirement)

HU-managed storage location:

1. Use transaction LT09 to move the SU back into it's original bin
2. Confirm the new TO (LT12)
3. On the pack screen for the delivery, delete the assignment of the HU's to the delivery
4. In the main delivery overview screen (VL02N), select the required item numbers, click on Edit, select "Copy Pack Quantities As Dlv. Quantities" & Save (Ctrl+S).
5. Delete the delivery or repick the delivery (based on your requirement)
