I upgraded the new Coresuite 4.0 on my system SAP Business One 8.82 PL13 last week.
But since then, it's no more possible the user the Swiss Payment. (All the rest is going good).
The error "No External Documents Found" and "Method not found: 'Void SAPBobsCOM.IDocuments.set_AttachmentEntry(Int32)' is always Coming when I try to validate an invoice from the Record Payment Slips window.
I guess it's coming from the new "External Documents" windows on the left side of the Record Payment Slips and the new menu "Readsoft Integration" in the Swiss Payment configuration.
Can anyone help me solving this problem ?
