Hello,

Can you tell me how does Proprietary Archive archive trend? Is it related to the quality of variables? Is there any difference between 'by change' and 'by period'(of course I mean the quality of variables)?

For example, when using 'by change',the bad quality of variable will not be archived even if value changed, yes? What about 'by period'?

Thanks

BRs,
Mark

Hmmm your question is not so clear Mark.

Are you talking ONLY about the case of bad quality or in general?

sorry for that.

ONLY about the case of bad quality for 'by change' and 'by period. But of course,if I can know more, it's better.

So, anyway 'on change' or 'by period' is the same whatever is for quality or value or TS.
The rule is:
- On change: Record the last point VTQ according the period defined on the trend IF V or T or Q change.
- On period: Record the last point VTQ according the period defined in the trend WHATEVER V, T or Q change or not. You can call it sampling mode.
