Returns the Product associated with the ProductVariant. Whereas the `ProductService.findOne()`
method performs a large multi-table join with all the typical data needed for a "product detail"
page, this method returns only the Product itself.
### getSaleableStockLevel

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, variant: <a href='/reference/typescript-api/entities/product-variant#productvariant'>ProductVariant</a>) => Promise<number>`}   />

Returns the number of saleable units of the ProductVariant, i.e. how many are available
for purchase by Customers. This is determined by the ProductVariant's `stockOnHand` value,
as well as the local and global `outOfStockThreshold` settings.
### getDisplayStockLevel

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, variant: <a href='/reference/typescript-api/entities/product-variant#productvariant'>ProductVariant</a>) => Promise<string>`}   />

Returns the stockLevel to display to the customer, as specified by the configured
[StockDisplayStrategy](/reference/typescript-api/products-stock/stock-display-strategy#stockdisplaystrategy).
### getFulfillableStockLevel

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, variant: <a href='/reference/typescript-api/entities/product-variant#productvariant'>ProductVariant</a>) => Promise<number>`}   />

Returns the number of fulfillable units of the ProductVariant, equivalent to stockOnHand
for those variants which are tracking inventory.
### create

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, input: CreateProductVariantInput[]) => Promise<Array<Translated<<a href='/reference/typescript-api/entities/product-variant#productvariant'>ProductVariant</a>>>>`}   />


### update

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, input: UpdateProductVariantInput[]) => Promise<Array<Translated<<a href='/reference/typescript-api/entities/product-variant#productvariant'>ProductVariant</a>>>>`}   />


### createOrUpdateProductVariantPrice

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, productVariantId: <a href='/reference/typescript-api/common/id#id'>ID</a>, price: number, channelId: <a href='/reference/typescript-api/common/id#id'>ID</a>, currencyCode?: <a href='/reference/typescript-api/common/currency-code#currencycode'>CurrencyCode</a>, customFields?: CustomFieldsObject) => Promise<<a href='/reference/typescript-api/entities/product-variant-price#productvariantprice'>ProductVariantPrice</a>>`}   />

Creates a [ProductVariantPrice](/reference/typescript-api/entities/product-variant-price#productvariantprice) for the given ProductVariant/Channel combination.
If the `currencyCode` is not specified, the default currency of the Channel will be used.
### deleteProductVariantPrice

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, variantId: <a href='/reference/typescript-api/common/id#id'>ID</a>, channelId: <a href='/reference/typescript-api/common/id#id'>ID</a>, currencyCode: <a href='/reference/typescript-api/common/currency-code#currencycode'>CurrencyCode</a>) => `}   />


### softDelete

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, id: <a href='/reference/typescript-api/common/id#id'>ID</a> | <a href='/reference/typescript-api/common/id#id'>ID</a>[]) => Promise<DeletionResponse>`}   />


### hydratePriceFields

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, variant: <a href='/reference/typescript-api/entities/product-variant#productvariant'>ProductVariant</a>, priceField: F) => Promise<<a href='/reference/typescript-api/entities/product-variant#productvariant'>ProductVariant</a>[F]>`}   />

This method is intended to be used by the ProductVariant GraphQL entity resolver to resolve the
price-related fields which need to be populated at run-time using the `applyChannelPriceAndTax`
method.

Is optimized to make as few DB calls as possible using caching based on the open request.
### applyChannelPriceAndTax

<MemberInfo kind="method" type={`(variant: <a href='/reference/typescript-api/entities/product-variant#productvariant'>ProductVariant</a>, ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, order?: <a href='/reference/typescript-api/entities/order#order'>Order</a>, throwIfNoPriceFound:  = false) => Promise<<a href='/reference/typescript-api/entities/product-variant#productvariant'>ProductVariant</a>>`}   />

Populates the `price` field with the price for the specified channel.
### assignProductVariantsToChannel

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, input: AssignProductVariantsToChannelInput) => Promise<Array<Translated<<a href='/reference/typescript-api/entities/product-variant#productvariant'>ProductVariant</a>>>>`}   />

Assigns the specified ProductVariants to the specified Channel. In doing so, it will create a new
[ProductVariantPrice](/reference/typescript-api/entities/product-variant-price#productvariantprice) and also assign the associated Product and any Assets to the Channel too.
### removeProductVariantsFromChannel

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, input: RemoveProductVariantsFromChannelInput) => Promise<Array<Translated<<a href='/reference/typescript-api/entities/product-variant#productvariant'>ProductVariant</a>>>>`}   />
