Combining a Linux capable CPU and MCU is not new or that weird... I think a Cortex A9 and Cortex M4 appeared on a combined SoC on the IMX6 platform around 10 years ago.
I integrate into SAP for manufacturing and the users can certainly do every transaction they need to do to account for cost and shipping product and keep finance / supply chain happy.
But yes, to actually plan and run their manufacturing area, that's where the software I write comes in... as well as a ton of spreadsheets :)
The cost/implementation of SAP is so big that the decision to use it can only be signed off at C-Level.
Any company who is looking at SAP is likely doing business in the US - Sarbanes-Oxley means CFO and CEO have to personally sign off on the financial accounts and are criminally liable (am sure it's the same in other countries).
SAP at it's core is all about financial control. SAP sell SAP to CEOs and CFOs by telling them it will provide strict financial controls to their company and avoid them personally going to jail / paying huge fines. It's an easy sell
Plenty of use cases in embedded!
