You can work with serial numbers if you or Extended Warehouse Management (EWM) create warehouse tasks, or when you confirm warehouse tasks.
If you confirm a warehouse task in the foreground, you can assign serial numbers manually. If you confirm a warehouse task in the background, EWM automatically assigns the serial numbers known to the system. A prerequisite for this is that a complete quant removal occurs and that the serial numbers have been defined.
You can display the serial numbers in the warehouse management monitor after saving (see Using Serial Numbers in the Warehouse Management Monitor). On the SAP Easy Access screen, choose Extended Warehouse Management ® Monitoring ® Warehouse Management Monitor. Select a warehouse task by double clicking it. EWM jumps to the display transaction for warehouse tasks (transaction /SCWM/TO_DISP).
EWM displays serial numbers in open, confirmed and archived warehouse tasks. EWM does not display or archive the serial numbers for quantity differences.
If you want to display serial numbers from open, confirmed or archived warehouse tasks, on the SAP Easy Access screen, choose Extended Warehouse Management ® Execution ® Confirm Warehouse Tasks. Select a warehouse task and display the serial numbers in the detail view for the item on the Serial Numbers tab page.
● If you confirm a warehouse task in the foreground, you can assign serial numbers manually in the following way:
○ From the list of predetermined serial numbers, choose the one which is required.
On the SAP Easy Access screen, choose Extended Warehouse Management ® Execution ® Confirm Warehouse Task and go from the detailed overview for the item to the Serial Number Current Value pushbutton on the Serial Number tab page.
○ Specify a serial number manually.
On the SAP Easy Access screen, choose Extended Warehouse Management ® Execution ® Confirm Warehouse Task and from there, go to the detail view for the item on the Serial Number tab page then Create. Set the Actual indicator for each serial number and manually specify the serial number.
○ If EWM cannot display a list of serial numbers, for example if a product has the serial number requirement Serial Numbers for Document Items or Serial Numbers at Warehouse Number Level, you can assign whole serial number ranges to a warehouse task.
On the SAP Easy Access screen, choose Extended Warehouse Management ® Execution ® Confirm Warehouse Task and go from the detailed overview for the item to the Serial Number Current Value pushbutton on the Serial Number tab page.

● If you want to confirm a difference quantity and you are working with a serial number requirement, you can specify serial numbers for the current value and the difference quantity. You can specify serial numbers for the difference quantity by using Serial Numbers Diff. instead of Actual Serial Number in the detail view for the item or setting the Diff. indicator instead of the Actual indicator for each serial number.
If you enter differences for a warehouse task, and you select Serial Numbers Diff., EWM attempts to determine possible predetermined serial numbers and displays them in the input help.
● If you are using the warehouse task for the low stock check, select Serial Numbers LS instead of Actual Serial Number in the detail view for the item, or set the LS indicator for each serial number instead of the Actual indicator.
● If you confirm a warehouse task and use the Check pushbutton in the overview for the warehouse task, you receive information about whether you have to enter serial numbers. This is dependent on the processing situation, that is, whether you want to specify an exception code or a difference quantity, or you whether you want to work with the low stock check.
● If you only want to partially confirm a warehouse task and you therefore split the warehouse task, EWM displays the serial numbers that have already been assigned to the warehouse task for the first warehouse task to be split. A prerequisite for this is that you have manually entered the outbound delivery quantity and the serial numbers.
● If you attempt to confirm a warehouse task without serial numbers, then EWM checks whether serial numbers exist for this warehouse task and, if so, it uses them. If no predetermined serial numbers exist and you carry out a complete stock pick from the storage bin, EWM uses serial numbers that belong to this quant. If no serial numbers exist and you only carry out a partial stock pick from the storage bin, you must confirm the warehouse task in the foreground and enter the serial numbers manually.
If you confirm handling units completely, you do not have to enter any serial numbers.
An exception occurs if you have implemented the Business Add-In (BAdI) /SCWM/EX_CORE_CO_SN_FORCE in such a way that the user must always enter serial numbers when confirming warehouse tasks.
