SAP Note 27945 - Subsequent debits/credits in long invoices

Symptom:

You want to post subsequent debits/credits for a purchase order containing so many items that these items cannot all be displayed on one screen page of the order item selection screen. You enter a "subsequent debit" indicator on the initial screen as a default value for all items. Then you choose 'Select all' on the selection screen and enter unplanned delivery costs.
When you post the invoice, all lines as of a certain line are no longer characterized as subsequent debits/credits. As a result, the purchase order history in the respective order items is updated differently than required.
