Processing Invoices After Background Verification 
Use
If invoices were verified as containing errors or were saved with the Invoice Verification type No Invoice Verification for time being, you have to process them manually before they can be posted.
Prerequisites
You use the Invoice overview to generate a list of invoices verified as containing errors and of those not verified.
Features
You can change the allocation criteria assigned to incorrect invoices or those not verified at all, for example, the order number might have been entered incorrectly and has to be changed or an additional allocation criterion entered.
You can change the item data (such as the quantity, the amount or the tax code) of incorrect invoices or those not verified at all.
You can change document header data, such as unplanned delivery costs.
If you save an invoice with the Invoice Verification type No Invoice Verification for time being and you now want to have it posted, you can change the Invoice Verification type to Invoice Verification in background at time point 1 or 2.

If an invoice was verified in the background as incorrect, you can change the Invoice Verification type to Invoice Verification in background again to have the system verify it again. You would do this, for example, if you had not yet entered the delivery to which the invoice refers.
