Under <legal entity>/Accounts Payable/Common/Vendors/All Vendors, Invoice tab, select New Vendor Invoice. I would like to make the Invoice date field required. I've tried to personalize it, and see that it's using the VendInvoiceInfoTable.DocumentDate field. I tried going directly to that field in the Data Dictionary and selecting Yes under Mandatory in the properties, but when I do that, when I try to create a new vendor invoice, it no longer auto-populates the Invoice Account for the selected vendor and it shows an Infolog message warning with the contents "Field 'Document date' must be filled in." Any ideas on how to make this a required field would be appreciated.
