can we add validation constraints on categories attributes

[former_member692234]

hi Expert,

as we can see that categories is not direct attribute of product Model its coming from relation. so my requirement is to apply validation constraint on this categories attribute. i tried the below code but unfortunately did not work.

INSERT_UPDATE NotNullConstraint; descriptor(enclosingType(code), qualifier); id[unique = true, allownull = true]                 ; qualifier[allownull = true]; severity(code, itemtype(code)); target[allownull = true]                   ; type(code) ; constraintGroups(id)                                              								    ; message[lang = en];
                                ; Product:supercategories             ;ProductSuperCategoryNotNullConstraint              ; supercategories            ; WARN:Severity               ; de.hybris.platform.core.model.product.ProductModel   ; Product ; defaultBackofficeValidationGroup,defaultBackofficeCoverageGroup ,rcValidationGroup,rcProductSuperCategoryCoverageGroup     ; Product super category must not be Null
