We have a question about the attribute properties drop down in AF. In particular, we would like to better understand the use of “Configuration Item” flag. We can read from the definition that this flag indicates that any attribute edited having this flag requires there to be a check in. My question is, what was the motivation behind this flag and this behavior (in AF, in PI Vision, in…)? The only thing we could think of is that several attributes taken together all having this flag could be checked in at the same time – that a configuration for a system is usually not just a single attribute but a group of attributes. Having a check-in enforces that all attributes change at the same time (which perhaps is better for an AF Analysis).
