Hi Elena
I might need more information to understand your request.
Let me recap:
1. You receive an invoice and book it as the type Supplier invoice - choose supplier and a contra account and a department.
2. Then you want to look at the supplier ledger card and see invoices according to department.
Is that correct?
And if so how does it benefit you so have the purchases split into departments?
As e-conomic is designed the department is attached to the account, not the supplier. The full amount is owed to the supplier, but can be split into more accounts and departments. I hope that makes sense :)
