# 链式转化报告中的推荐窗口说明
你必须了解 2 个推荐窗口： *链式动作推荐窗口* 之间。 *点击推荐窗口*。推荐窗口只能在以下部分中更改： *模板条款* 部分中，在……下 **合同** 位于左侧导航菜单中。
1. 在左侧导航菜单中，选择  **\[互动]** → **合同**.
2. 选择 **模板条款**。你可以修改或设置模板条款并指定推荐窗口。
了解更多关于 [合同和模板条款](/brand/zh/what-would-you-like-to-learn-about/platform-features/contracts-and-template-terms/learn-about-template-terms-and-contracts.md).
{% tabs %}
{% tab title="链式动作推荐窗口" %}
此链式动作默认期限为 5 年，因此从跟踪父级动作到跟踪某个子动作之间可间隔 5 年。超过 5 年后跟踪的子动作将不会与其对应的父级动作关联。此时长可调整为更短。
{% endtab %}
{% tab title="点击推荐窗口" %}
此链式动作默认期限为 180 天，因此从合作伙伴带来的首次点击到跟踪父级动作之间可间隔 179 天。如果父级动作（例如应用安装）发生在首次点击后 180 天以上，则不会跟踪父级动作。根据业务决策以及对品牌在各事件之间的合理性，此时长可调整为更短。
{% endtab %}
{% endtabs %}
示例场景
作为品牌方，你希望将推荐窗口设置如下：推荐窗口和点击窗口均设为 45 天。
你还拥有链式动作：免费试用注册和付费订阅事件。你将把这些付费订阅事件批量导入，并将归因策略设置为如下：免费试用注册获胜，然后级联到最后点击。
如果在 45 天后提交动作会怎样？为了让推荐窗口和点击窗口在文件于 45 天后发送时仍然适用，提交文件时提供的日期必须少于 45 天，或在指定的推荐窗口和点击窗口范围内。如果动作日期超过 45 天，impact.com 会将其归因于点击；如果点击窗口也超过 45 天，则会报错且不会找到推荐来源。
超出两个窗口之外的动作将出现以下错误原因： `NO_VALID_REFERRERS_FOUND OUTSIDE_ASSOCIATION_WINDOW`。你可以在……中找到这些动作 [无效转化](https://app.impact.com/secure/advertiser/engage/actions/admin/integrated/viewReport.report?handle=adv_invalid_conversions) 报告中。

## 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://help.impact.com/brand/zh/what-would-you-like-to-learn-about/platform-features/actions-and-payouts/chained-action-reports/referral-windows-for-chained-action-reports-explained.md?ask=&goal=
```
`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.
