inUse property

Indicates whether this attribute has been used by any products.

True if at least one Product is using this attribute in Product.attributes. Otherwise, this field is False. CatalogAttribute can be pre-loaded by using CatalogService.AddCatalogAttribute, CatalogService.ImportCatalogAttributes, or CatalogService.UpdateAttributesConfig APIs. This field is False for pre-loaded CatalogAttributes. Only pre-loaded catalog attributes that are neither in use by products nor predefined can be deleted. Catalog attributes that are either in use by products or are predefined attributes cannot be deleted; however, their configuration properties will reset to default values upon removal request. After catalog changes, it takes about 10 minutes for this field to update.

Output only.
