Unable to reserve stock from a Pick List v15

I am currently using ERPNext v15.88.1 and I am a new user to ERPNext.

When submitting a Pick List from a Sales Order, I am unable to create a Reservation entry. The option is available but clicking the button doesn’t do anything. I have checked the following:

  • I have available stock and the stock is in the corresponding warehouse.
  • “Enable stock reservation” is selected in the stock settings
  • “Is stock item” is checked

I have noticed that when submitting the Pick List, the “Picked Qty” is filled out automatically and if I check the option for “Scan Mode”, the pick quantity needs to be entered in order to submit the Pick.

Is there a known bug with this version or is there something I am missing?

I have since worked out that my issue is regarding Product Bundles. When a normal item is added to a sales order, the reservation works fine. However when using Product Bundles, the items within the bundle are not able to be reserved.
