Setting the Earmarked Funds to Complete 
You definitely have to set the "Complete" indicator if the amount of the earmarked funds is greater than the invoice amount. As long as the earmarked funds is not marked as complete, budget is linked to the amount of the difference amount between earmarked funds and invoice amount.
An earmarked funds can either be set to "Complete" (end indicator) in the earmarked funds document itself or from the transaction for the request.
All invoices, which are to be assigned to the earmarked funds, have come in.
The complete indicator has the effect that:
The assigned values updated by the earmarked funds are canceled. This means that the assigned value of the FM account assignment is reduced and the unused funds are returned to the budget of the FM account assignment.
This item from the earmarked funds document can no longer be changed;
Reference can no longer be made to this item in the posting procedure.
Note
The complete indicator can be canceled in the earmarked funds document per document item.
