You can optimize system performance during radio frequency (RF) picking.
Recommendation
Use asynchronous processing only when necessary as quicker response times increase system load, which can have a negative effect on the required system sizing.
During pick warehouse task confirmation, the system also updates the corresponding outbound delivery order item. To improve the response time of the warehouse task confirmation step, the system can perform the delivery update asynchronously in a Remote Function Call (RFC) queue. You can monitor the queue for message queue group /SCWM/INT1 - Warehouse Internal Messages
in the warehouse management monitor under .
You can activate asynchronous delivery update on the SAP Easy Access
screen under .
To improve the response time of the warehouse task confirmation step, you can activate asynchronous pick warehouse task confirmation. With asynchronous pick warehouse task confirmation, the system presents the next RF screen before updating the database. You can activate asynchronous pick warehouse task confirmation on the SAP Easy Access
screen under .
The asynchronous pick warehouse task confirmation can fail if, for example, the Customizing settings for the storage type allow the available quantity to be a negative value. For more information, see Error Handling.
The system creates the pick-handling unit (pick-HU) warehouse task from the resource to the destination bin when confirming the first pick warehouse task into the HU. To improve the response time of the warehouse task confirmation step, the system creates the pick-HU warehouse tasks asynchronously in an RFC queue. You can monitor the queue for message queue group /SCWM/INT1 - Warehouse Internal Messages
in the warehouse management monitor under .
You can activate the asynchronous creation of pick-HU warehouse tasks on the SAP Easy Access
screen under .
The asynchronous creation of pick-HU warehouse tasks can fail if, for example, the destination bin for the pick-HU is blocked. For more information, see Error Handling.
Warehouse task printing and HU printing are called during warehouse task creation and warehouse task confirmation. The function modules call the Post Processing Framework (PPF) which reads the relevant Customizing and calls the schedule condition for all active PPF actions. The schedule condition checks whether the warehouse process type or the packaging material type has a determination procedure from the assigned condition technique. If there is one, the condition technique is called, and based on the result, the system determines whether or not to print.
If you know that you do not want printing as part of this process, you can control whether or not the PPF is called.
The queue has a field (QUEUE_PRINT
) for setting up printing during warehouse task creation and confirmation. The field has the following possible values:
' ' – call PPF
1
– do not call PPF
You can change the value of this field in Customizing for Extended Warehouse Management
under .
The resource has a similar field (RSRC_PRINT
) with the following values:
1
– call PPF
2
– do not call PPF
' ' – the queue value decides whether or not to call the PPF
You can change the value of this field on the SAP Easy Access
screen under .
With the RF framework, you can send messages from the warehouse management monitor to resources. However checking for potential messages can consume system performance. Therefore you can turn messaging off on the SAP Easy Access
screen under .
