While testing the process of creating warehouse shipments I stumbled across an interesting issue. After creating the warehouse shipment from the sales order, I was presented with the message below:

Success! I’ve created the warehouse shipment. I clicked OK but was then presented with the message below:

Hmmm. Something isn’t right. I’ve created warehouse shipments before following the same steps and never had that message. To ensure the shipment had created correctly I clicked Navigate > Whse. Shipment Lines and was presented with the shipment lines as per below. Everything must be fine after all.

I made a note of the warehouse shipment number and hopped over to the Warehouse Shipments page to continue my task however SH000010 wasn’t listed.

I checked for filters and it was at this point the penny dropped. When I setup my user I didn’t add myself as a “Warehouse Employee” for all locations.
Therefore, to fix the issue I went to the “Warehouse Employees” page and added myself as a user of this location:

Warehouse Employees
Once I had done this I could see the warehouse shipment. This also explains the strange “The record you tried to open is not available. The page will close of show the next record” message when creating the warehouse shipment.
Thanks for reading
