At this time the best method I have successfully used in several Multi-Company Environments is.
Create Company_UD.LogoPath_c and since its on the Company table it will easily exist in RDDs. You can also then use it in BarTender, BAQ Reports etc…
Add it to Company Config and give the Epicor Service Accounts or All Users Readonly access to the Logo UNC Path.
In SSRS / BarTender its then just about referencing the external image.
However the Key is that you put a fixed dimension for all logo’s if you have MC. Make each one fit in lets say a 500 x 311 box, don’t vary in dimensions.
For a single company or single-plant, you can just embed… But in a MC company, imagine embedding 20 images
