"Lot size value" error message whlie register arrivals

Hi,

May be you can check the debug console to find out what is the exact place for this error. You can get a indication like whether that come from event or IFS db code

@Link I just run a select to see where this text is displayed. I see it’s coming from a Shop Order

Is this a PO that originated from a Outside Shop Order operation? I would suggest to check the Shop Order linked to this PO.
