Hi @Ruth Entwistle,We had a similar situation in #NAV2016 where the users had appropriate permission but received that error when using a limited license.
I'm not sure of the exact limitations of the limited license, but we found if they open NAV, and go directly to the table/page (i.e. Purchase Orders) they're needing, they're able to do what they need.
However, if they go to other pages first (i.e. a Sales Order, then the customer card, then the requisition worksheet, then the Purchase Order), they would receive the error.
The only other way to get around the error, that we found, was to assign them a full user license.
