Specifying Serial Numbers for Warehouse Task Creation
Use
In Extended Warehouse Management (EWM), you can work with predetermined serial numbers in outbound deliveries and posting changes. For example, the ERP system can send serial numbers to EWM in outbound deliveries.
If, for example, you use an advanced shipping notification to specify serial numbers in inbound deliveries, EWM does not take the specification from the inbound delivery into account initially. EWM only copies these serial numbers into the corresponding warehouse task once you have confirmed the corresponding warehouse task.
Features
When EWM receives serial numbers from another system, it checks whether they are predetermined serial numbers. For inbound deliveries, EWM copies the predetermined serial numbers into the inbound delivery notification and into the outbound delivery request for outbound deliveries.

or
Serial Numbers at Warehouse Number Level
. EWM copies the predetermined serial numbers into the delivery documents of the inbound and outbound deliveries. However, you must ensure that EWM creates the pick-warehouse task in accordance with the predetermined serial numbers for the outbound delivery order. You must therefore also confirm the storage bin that specifies the respective serial number.

Serial Numbers in Inventory Management
. EWM copies the predetermined serial numbers into the delivery documents of the inbound and outbound deliveries. EWM also determines the corresponding location data and handling unit (HU) data for the predetermined serial numbers. EWM needs this data to create corresponding warehouse tasks. If EWM cannot determine this data for the predetermined serial numbers, EWM triggers a
pick denial
in the outbound delivery process. While EWM carries out the pick denial, the system determines the serial numbers for which the system could not create warehouse tasks.
If you are working with predetermined serial numbers in inbound deliveries, you can manually overwrite these serial numbers. If you are working with predetermined serial numbers in outbound deliveries, you can confirm these serial numbers only. You cannot specify any other serial numbers in the corresponding warehouse task.
If EWM displays a warehouse task in display mode, then you can also only display the corresponding serial number.
Executing a Pick Denial
If you or EWM carry out a pick denial, EWM saves the serial numbers for the quantity difference in the outbound delivery order. EWM flags unconfirmed serial numbers as invalid. This prevents EWM from creating new warehouse tasks for these serial numbers. You can display the indicator in the outbound delivery order. On the

Splitting Warehouse Tasks
It is possible that EWM may have to split a warehouse task. For example, if the outbound delivery quantity exceeds a certain capacity. EWM splits the warehouse task into two warehouse tasks. One for the allowed outbound delivery quantity and one for the excess outbound delivery quantity. EWM reassigns the predetermined serial numbers in accordance with this split and the outbound delivery quantity. EWM also does this for outbound delivery splits that occur during packing (see Integration of the Serial Number in the Delivery under ‘Delivery Item Split’).
Cancelling Warehouse Tasks
If you cancel a warehouse task in the user interface for the outbound delivery request or the outbound delivery order, EWM also deletes the corresponding reservation of predetermined serial numbers and unlocks these serial numbers.
EWM does not display these serial numbers in the warehouse task or save them.
