Shipment created in ECC when difference in quantity from EWM during PGI of TU

Hi,

I've created an Outbound Delivery Order in EWM through STO from ECC which had a material of quantities 2, and 3 units each in Two HUs. I loaded these HUs to a TU and assigned the OBO to the TU and I posted the Goods Issue for the TU.

Got an error that a difference in assigned and total quantity observed and hence a new shipment is created in ECC resulting in failure of the process.

Please let me know, how to track the newly created shipment?
