When setting up return reason codes, it is possible to map a default location, which is very useful.

There is also the possibility to tick a Boolean "Inventory Value Zero' against a return reason code.

This Boolean does nothing, when it should allow to bring stock back, with no inventory cost transactions recorded.
This way, a return reason code of 'damaged' could be used to bring stock back , but not reverse the CoS of the product.

In some cases, this would be a really useful feature, and it's frustrating that the feature appears to be present, but does nothing at all.
