# 3.10.8

Release Date: June 20, 2022

## **Store Manager**

### Child item cost is updated when a purchase order or transfer in containing parent item is received

Starting with release 3.10.8, when a purchase order or transfer in that contains a parent item is marked as received, if the store uses a **Cost Update Method** (Last Cost, Weighted Average, or Landed Cost) to calculate item cost, the item cost for both the parent and child items are updated. Prior to release 3.10.8 only the item cost of the parent item was updated.

The **Cost Update Method** is selected under **File** | **Configuration** on the **Inventory Rules** tab. If a Cost Update Method is selected, the formula used to update the item cost of a child item is **\[new cost of parent item] / \[child item quantity]**. The new cost of the parent or child item displays in the **Cost** field on **General** tab of the Item screen. The quantity of the child item displays in the **Child Quantity** field on the **Special** tab of the Item screen.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.rmhpos.com/releases/old/3-10-8.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
