Yes, there is a Capita known issue with OneDrive and 'SIMS My Documents'. Apparently only around 3 or 4 people have logged it so far.
If you redirect your My Documents folder etc to OneDrive rather than a network or local drive you will no longer be able to run reports. The reports issue is apparently because when you run a report it stores the base report in your 'SIMS My Documents' and also a macro to build the data within Excel, for example. However SIMS cannot reference the Macro from OneDrive and therefore fails. This happens whether the report is stored or created Ad-hoc.
Capita are aware of the issue and their initial response was that SIMS was built prior to OneDrive so we won't be implementing a fix and I should wait for their online version to come out. While I understand the response (not about their online version!) I would have thought they might want to create a fix with so many schools starting to think about OneDrive. They could have an .ini file to redirect 'SIMS My Documents' to a local drive.
I have escalated the issue within Capita however haven't heard anything since.
