One team I support has created a configurable product structure with multiple level migrated from ERP variant configurator.
The surprise for them has shown up at the time or doing variant updates via reconfigure (a lower level configurable module components have changed). On reconfigure the system determines there is input match but the structure has changed (no-matching-variant), and it offers to update the variant. However, it only updates/iterates the level at which you configure, AND creates NEW intermediate variants in the path up from where the change happened (instead of iterating them or offer level by level updates).
I see that there was a case open (Article - CS213714) but it seems it has been dropped by R^D after some time.... Has anybody found a workaround or alternative way to achieve interation/updates on all levels instead of creation of new variants? Or enven some approach to organize these types of models in a diffferent (more robust manner to limit variant proliferation).
