Bug Fixes and Minor Adjustments

• Fixed: in P9, model options on a general assembly item would get popped twice.
• P10: fixed issue that attempted to set the job ID to a blank string on a PO, which prevented the PO from saving.
• P10 will now respect the “Disallow all unpost buttons” security setting.
• Changed trip selector dropdown to only show valid trips rather than all trips when the “All Warehouses” checkbox is checked.
