value entries are not generated

I have the following problem. I have found value entries witch are generated from the delivery note and not from the invoice. All other value entries are generated from invoices. What is the reason for this problem?

Hi Dirk, I’m not sure I understood your problem, if you post Ship and Invoice the value entry is created only by the invoice, if you post only Ship and after you post the Invoice, the value entries are created by both documents. Elena
