Has anyone come across this error before at all? 

User reports getting this error when RMB/create invoices on the "External Supplier Invoice Load Information" screen. 

Permissions look like they’re exactly the same for this user as others running the same process.  No-one else reporting this issue.  I logged on as user.  If I process from "External Supplier Invoices" screen it works fine.  If I process from "External Invoice Supplier Invoice Load Information" it falls over.  

File is coming from our external expenses software.  I am advised there aren’t any issues with User setup/permissions from this software - though it shouldn’t make any difference as it’s just import of an external file.

User has DocMan permissions and is in the appropriate Doc Group.  

Any thoughts/suggestions/ideas would be appreciated.

Thanks
Linda
