What causes this issue?

You have not specified a PO Box postal code for a PO Box address,

check customizing in the general settings.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

If the 'PO Box postal code required' flag is set, you must maintain the
PO Box postal code if a PO Box is specified (or the 'No PO Box number'
flag is set).
