The Process automation in Accounts payable can be used to schedule and automatically generate payment journals using Payment proposal. This process uses a Vendor disbursement journal name. On Vendor disbursement journal name setup, there is a flag to Summarise amounts in bank account and ability to define summarisation criteria however the Process automation doesn't consider or respect this setup when the journal is created, for e.g. if you have summarisation setup, the summarisation flag on the payment batch header will still be No summarisation and has to be manually updated. The idea is for the Process automation to consider and respect this setup on the Journal name.
