What is the use of prefixing product IDs?
A prefix distinguishes items from different shops or integrations. Under Basic settings, set a stable, unique shop prefix when your setup requires it.
In the normal mode, the ID combines the shop prefix, the feed country code and the product ID. Fictional example: prefix BM, United States and product 6 produce BMUS6. A combination adds the configured separator and its ID, for example BMUS1v2.
Simple ID mode removes the prefix and country code, but retains a combination suffix when combinations are exported separately. PRO can offer other identifier sources; check its active mode.
Avoid changing existing IDs: this can create new Google items and break advertising-tracking matches. Compare an actual XML value with the tracking value before any change. See formulas and examples.
