Automatic UD for partial lots

Hi,

We have set up a prototype to use QM for the ARM material inspection in a customer returns process.

We use inspection type 10 to create inspection lots when booking GR on the return delivery. This works fine but in ARM SAP Standard always creates exactly one partial lot for the delivery quantity.

Now when recording the results and everything is fine, I would like to automatically close the UD using QA10. But I can not find any customizing or function modules which would allow me to take an automatic usage decision on lots containing partial lots or partial lots.
Can this only be done interactively?
