Hi,
We are finalizing our setup with Business Central SaaS, but have other internal warehouse management software that we use to match purchase invoices to our bookings and also for creating sales invoices. Sales invoice image is created on our on-prem folder and this image should be available for Business Central. How could this be achieved? We have API integration to put header and line text-level information to BC, but how about the actual image files? I know there is Attachment API available, but are there any other possibilities? Could we for example use SharePoint? Save the file from WMS to SharePoint-folder and BC could access the invoice image from there? That way no files would have to be moved, only link to the file.
Also as for our purchase invoices, we have an operator who uploads our purchase invoices to our FTP. From there they are uploaded to BC via ExFlow (finvoice transformation tool). The purchase invoice is then forwarded from BC to our WMS for matching adn approval. If we use attachment API to forward the actual pdf-image, it would grow amount of storage eventually needed as the files are stored on multiple locations.
So therefore i am wondering how would be the best way to integrate SaaS version with our on-prem environment? SharePoint would be one possibility, but there is not much information available.
