We have an issue where we find users gets unassigned from projects which leads to access issues. The only way is to add them back. We have seen this issue in previous versions as well. Anyone else faces this issue and is there anyway we can put some trigger or mechanism to capture when this happens or to prevent it?
I haven't experienced this. But, I did a quick search of GTAC and as you say, it has happened in previous versions.
On the post below, the customer reported they used query_xml utility daily which output projects and members. Maybe you could utilise this method somehow? Export a report daily, and a script could compare it with the previous days report and highlight differences?
