If an invoice from Dimensions is not showing in Access Approve, it could be for one of the following reasons:
If this is affecting a single user (and your other approvers are seeing transactions as expected, then please check whether the user in Dimensions or Financials is set up with access to the Invoice Register, is an approver, and the transactions in question are going to the correct account.
If invoices are not appearing in approve for any user, the first step to take is to make sure the aCloud Approve Service is running. This will usually need to be checked by your IT department (note that if you are an Access Hosted Client, you will need to raise with Support to have this checked).
Go to the server which the aCloud Approve Service is running on.
If the service is not switched on, right click and press start.
If either your service is already running, or you are an Access Hosted Client, please raise a new case online.
