Issue Summary

When Reporting Picking on a Shipment, IFS is seemingly randomly changing the Handling Unit ID associated with a Shipment Line. 

The issue occurs approximately 1-2 times a month and we can’t understand the cause and therefore unable to recreate the issue the test environment.

Issue Detail

2 Shipments have been processed on 10/1/25 for the same Qty of the same Lot Batch of a foods.

Part Description: LAVANDA F  214581

Lot Batch: 49121/24

Qty: 25KG

Original Handling Unit ID: S25KG (1 container)

The Inventory Transaction History shows the following:

On Shipment ID: 61259, the Report Picking correctly Issued / Received / Shipped the 25kg in the Handling Unit 728221.  Working as expected.

However, on Shipment ID: 61258 which was processed 15mins earlier, between the PICK-IN and OESHIP Transactions, the Handling Unit ID has been changed from 1 x S25KG (728220) (1 x 25kg Steel Drum) to 250 x A100G (250 x 100gram containers).

We’d like to understand what triggered the Change Handling Unit on Shipment 61258.  I can confirm both Shipments 61258 & 61259 were processed by the my self followed the same steps to Create Pick List and Report Picking.
