Hello,

 

I had a quick question. We are trying to reserve supplier material for a part but we keep running into this error message? Any thoughts? Does this have to do with the inventory availability planning? Thanks.

Hi ​@jayoneil98,

The reason for this message is that the 'Availability Check' check box on Inventory Part (Misc part Info tab) is ticked. Hence when executing the RMB Reserve in Supplier Material for Purchase Order Line, and entering a qty to be reserved, the system performs an availability check. Even though you may see enough on hand quantity in the inventory for this part, some of this quantity could be with ownerships: customer owned or supplier loaned. Then stocks with that type of ownerships are excluded by the availability check.

 

This problem can be get around by unchecking the "Availability check" tick box on the component part (Inventory Parts). Basically, we should not perform the availability check against the parts with ownership type "Customer Owned" and "Supplier Loaned" as these parts are not belonging to us. 

Thank you!

Hi,

Yes, you can say that. One or more components are using the “availability check” (the toggle is selected) defined on Inventory Part.

And here, when doing reservations, system really gives you hard errors if the availability check lookup doesn’t find enough “Plannable Qty”. In your case plannable qty goes below zero.

Cheers,

Mats
