There is a function in the application that uses the most common coding as a coding suggestion. For this to apply, the following is necessary:

• The invoice is a cost invoice.
• The invoice has no cost lines coded.
• There is a "most common" coding on the current company + vendor to apply. For this it takes that at least 3 invoices have been coded the same and are final posted.
• The UseFrequentAllocationProposal parameter is enabled.

This also includes that if you have the parameter UseFrequentAllocationProposal activated and have coding suggestions that only code reverse tax will work to "take over" and put in the most common coding instead. To get around this, you add a cost line in the coding suggestion with reverse tax.
