How to Confirm SiteLogisticsTask via Webservice?

Dear community,

I would require your help regarding a confirmation call to a SiteLogisticsTask.

The system has an open task (nr. 5), which resulted from an inbound delivery. The task is to put the material on stock, hence an inbound task.

I would like to confirm the task with the actual quantity (in this example open quantity = actual quantity).

I do get a "5Saved Successfully" response, but the task is still marked as open and I don't see the confirmation on the UI.

Do you have any ideas on what might be the issue here?

What is missing / too much to trigger the creation of a confirmation?

Thanks in advance for your help!
