Error message: "DIMENSIONIERUNG_UNGUELTIG / _NICHT_VORHANDEN / _WERTE_IDENTISCH" - (Dimensioning invalid / not available / identical)
This error occurs when a SKU is combined with other SKUs in a productReference and thus exists as a variant, validation stage 2 checks whether the desired variant formation can take place on otto.de. However, if there are no variant-creating attributes, if the SKUs do not differ in the variant-creating attributes, or if the SKUs within a productReference have different variant-creating attributes maintained, otto.de cannot combine them into one offer on otto.de.
To avoid this error, It must be ensured that at least one variant-creating attribute is maintained (e.g. color) and that the SKUs within a productReference differ in this.
To identify the variant-creating fields of otto.de, the field "featureRelevance=VARIATION_THEME" must be read from the category retrieval and displayed in the mapping interface.
