Incomplete download to AC800M controller
A download has been done to a PM861A controller, but it marked the download as incomplete. Now any subsequent downloads require a cold download to the controller which cannot be done since it’s a common controller for providing data to multiple controllers. Could this be a memory problem? Is there a way to clear this message or to not check the memory quota to enable a download without a cold download.
If this is related to memory, splitting the application will be considered and a larger controller will probably be installed, but this will be during a maintenance shut.
For now, it would be great if a warm download is possible.

It happens. Sorry.
It seems to happen more often when your controller is being downloaded with many many changes ie during commissioning. The existing application is still running but you will need to cold restart the controller to be able to make any more changes.
Is this a "memory problem" ? Its hard to say. Every time I have seen the problem it does seem to be related to memory creep or fragmentation that occurs every time you download. Cold starting a controller after a long period of commissioning does seem to make subsequent downloads much faster.
At Online analysis sub-display (after you press download and select the controller -> Download) there are Restart choises - you have to select Warm there or Init.
Please check if Cold is selected instead?
What does it mean download is incomplete? Did you succeed to download without this message? Is the application running?
Please check explanation for RESTART in help of Control Builder
I think this Message means that the last download was actually not successful, Control Builder crashed or something similar.
If you are downloading from multiple Engineering Stations, try to use the same Station as for the last download to the Controller, but if you get the same Message i believe there is no other solution than to reset the Controller.
