Processing of Changes and Deletion of Forwarding Orders and Forwarding Quotations 
The forwarding order data received from your ordering party can change during the process. The change controller in SAP Transportation Management (SAP TM) checks whether forwarding orders or forwarding quotations have changed and propagates the changes to the freight unit. You can define how the change controller executes the changes as follows:
Synchronous
Asynchronous
Synchronous with fallback to asynchronous
You have defined the way the system propagates the changes to successor documents in Customizing for SAP Transportation Management under
and under
You have implemented the batch report Background Job to Process Triggers Periodically (/SCMTMS/PROCESS_TRIGGER_BGD), in case you process the changes asynchronous.
You have created the necessary change controller strategies and change controller conditions in Customizing for SAP Transportation Management under .
You have specified whether freight units can be deleted or canceled in Customizing for SAP Transportation Management unter .
You can change forwarding orders or forwarding quotations, for example, dates, locations or weights. The system updates the freight units automatically when saving the data.
You can change and update forwarding order or forwarding quotation data and add and delete items, even if the freight unit is already built and the planning is completed. The system updates the freight units when saving the data.
If you perform the changes asynchronously, the system can change the freight unit even if another process locks it. The system updates the freight unit as soon as the freight unit is unlocked. The system processes the changes in the background using the Report Background Job to Process Triggers Periodically (/SCMTMS/PROCESS_TRIGGER_BGD).
You can check in the application log if the system correctly propagated asynchronous processed changes. Open the log in the SAP Easy Access Menu under .
If you perform the changes synchronously, the system informs you immediately about a locked freight unit. You can not propagate the changes.
In case the forwarding order or forwarding quotation has the approval status Approval Needed and with your change the approval becomes redundant, the system deletes the workitem from the workflow.
You can cancel forwarding orders and forwarding quotations. The system either deletes or cancels the freight unit. If you have specified, that the system can only cancel freight units, the freight unit remains with the status Canceled. Otherwise, the system deletes the freight unit.
In case the forwarding order or the forwarding quotation has the approval status Approval Needed, the system deletes the workitem from the workflow.
