After testing the Collection process automation is was identified that project invoices were not included.

This is a known issue for Microsoft but it seems that is not on their roadmap.

We understand that a feature like this only make sense if it covers all type of invoices. Processing collections only for part of the debt of a customer is ot an option.

If the company only process project invoices then it even can't use the feature.

Please, conside to include the projet invocies on the collection process automation as soon as possible.
