How To Fix VL458 - Batch main item &1 is already packed. HU management is not possible

SAP Error Message - Details

• Message type: E = Error

• Message class: VL -

• Message number: 458

• Message text: Batch main item &1 is already packed. HU management is not possible

What causes this issue?

For the item category of the main batch item, an <DS:DE.CHHPV>indicator
</> controls that all the cumulated total quantity of all split items
should be packed for an item with batch management requirement. This
setting is overwritten by the system if at least one
<DS:GLOS.3526BE8FAFAB52B9E10000009B38F974>batch split item</> is
assigned to a HU-managed storage location. This ensures that only the
split items are packed (compulsory if you use
<DS:GLOS.35CEB720B3CC735DE10000009B38F982>Handling Unit Management
</>).
The checks on the delivery have shown that the main batch item &V1& is
already packed. Therefore, you cannot assign a HU-managed storage
location to the dependent batch split item because it is not possible to
pack the split item as long as the main item is packed.

System Response

The system outputs this message in order for you to correct the
delivery. You cannot save the delivery as long as the packing data
contains errors.

How to fix this error?

Call the packing transaction and unpack the main batch item &V1&, or
ensure that none of the batch main items for item &V1& is assigned to a
HU-managed storage location.

Procedure for System Administrators

If necessary, check your Customizing settings to see whether the item
category is set up correctly. To do this, choose the activity
<DS:SIMG.SIMG_CFMENUOLSDVOLB>Define Item Categories for Deliveries</> in
Customizing for Shipping.
