When an analysis is backdated in vintrace the system will try to roll forward the analysis, there are a couple of restrictions with this however.
The first is if another analysis has taken place already, if the metric that had analysis recorded against it has had a more recent reading the analysis will not be rolled past this point.
The second is if a new revision of the wine is created (this happens when wine is topped, blended, partially transferred, pressed, etc. In short, anything that could change the composition of the wine or split it up). In this case the analysis will be rolled forward to this point.
If the wine has changed vessels between the scheduling of analysis and the recording of it and the revision is the same the system will ask if you want to apply the analysis to the current state as well.
Included below is a couple of screenshots of examples where a roll forward of metrics will be stopped to help visualise it better.
This first one demonstrates an analysis backdated behind a pressing operation. The analysis will apply to the extracted must that was recorded prior to the backdated analysis.
This one demonstrates a Malic analysis backdated past two additions and a treatment, but is stopped by the top analysis because it also contains a Malic reading.
If you have any other questions regarding how metrics are backdated in the system feel free to contact support.
