This clip I've been asked to effort it with a modular tract --- EmployeeID, astatine the AccountingEntry.Item level. I've added the beneath enactment to the XML representation arsenic shown successful the guide:

And the existent Excel record lets maine adhd the column, and doesn't kick erstwhile the accusation is saved; it creates a income diary introduction voucher. However the Employee ID is empty:

I besides tried with information benignant xs:string alternatively of tns:IDType --- aforesaid result. I don't think it's a question of information benignant compatibility (the maximum magnitude of IDType is fixed arsenic 60 characters), arsenic the External Reference astatine header level has a maximum magnitude of 35 characters, but I'm blessed to beryllium proved wrong. Has anyone immoderate ideas?

Thanks,

Lewis
