Ideally how much time it takes to upload the scanned invoice of size less than 20 MB
SAP Business ByDesign
Depends on few things like size, if there is an issue processing, etc it will keep retrying in the background. but in the front end will have status 'Scanning In Process' and you wont see if it failed for any reason the first time, but later it worked for the second retry etc.
This is just an example for reason why one document might take longer than the other.
We don't expect the upload to take more than 1.5 minutes on a max
