We have found that while posting a packing slip through the item arrival process, some users quantity parameter is set to ‘All’ and others are set to ‘Registered’.
For the ones that are ‘All’, we did find the setting in setup → parameters that will prompt the user as to whether or not they want to change it.
It seems that you cannot change the value in the field from the form itsself like you can if you are posting the packing slip directly from the purchase order.
With different users having different values, obviously there is a way to change the value.
How would you go about changing a users value from ‘All’ to ‘Registered’?
