2020-02-24 Add Activity & Chatte

目前有个需求是需要在每个Object的Page Layout的显示Activity，Chatter的tab，但是有些 Custom Object需要一些设置才可以看到。
1.关于Activity Tab的显示，我们可以通过以下步骤去设置，也可以参考文档https://help.salesforce.com/articleView?id=000324086&language=en_US&type=1&mode=1：

Lightning: 

1. Go to Setup | Object Manager 
2. Open the custom object from the list
3. On the Details click Edit
4. Select the Allow Activities checkbox under 'Optional Features'
5. Click OK on the confirmation dialog to finalize
6. Save

2. 关于Chatter Tab 的显示，其实就是Enable Feed Tracking，具体步骤如下：

Step 1: Go to Setup, search Feed Tracking in Quick find box. Then select Feed Tracking.

Step 2: In the available object list click on Custom Object.

Step 3: Check Enable Feed Tracking check box.

Step 4: Select which field we need to track. In Custom Object we will track Amount and Date field. So check these two fields as shown in below picture.
Step 5: Then click Save. Finally we enabled the chatter for Custom Object

这样我们的设置就完成了，是不是很简单！！！
