not enough rights use table 'last value' (SysLastValue)

“not enough rights use table ‘last value’ (SysLastValue)”

I’ve asked an end user to delete their usage data for form related issues/problems they are having. The end - user received the above error. Is this permission related?

AX 2009, on a terminal server where I have no problems.

So, how is the user deleting this? It sounds a permission related issue.
