#358 Model Writer do not safe all raw data in case of One-Step Fit

[Matthias Filter]

In case of models created with the one-step-fitting approach it seams that the Model Writer node save / attach only one data record (several times) to the model instead of saving / attaching all different data records used for model fitting.
See attached workflow.

[Armin Weiser]

the workflow has only one single estimated primary model named "TEST-Model". But different secondary models and timeseries data sets.
Firstly: the database structure is not designed for "one primary" vs. "many time series"
Secondly: Even the estimated secondary models do not correspond logically with the time series (i.e. estimated secondary model ids point to different time series)

[Christian Thöns]

That's the structure for models created by "One-Step-Fit". There is a global model (primary + its secondary models), that is combined with each time series.

I know, that the DB is not designed for "One-Step-Fit" models. So we have to decide, if that feature is important enough to implement it in the DB.

We should consider to make the necessary adjustments to the DB somewhen.
