Going by your description, are you using Power Automate desktop or the Automate feature in excel? I was more thinking of the cloud service (it used to be called MS Flow) for this, however… the cloud service would need access to one drive, your data warehouse and the SAS reporting service to do this. And, as pointed out previously, the learning curve for Power Automate can be frustrating but once you get the knack of things it can be really useful. Perhaps a long term plan!
Good Luck with getting this sorted, things like this drive me mental at work!!
