我迅速检查了一下在香草的情况下。这些是我的观察。

I quickly checked in a vanilla instance. These are my observations.

实际上有两种挂锁。

红色挂锁。这不会以呈现的形式显示挂锁。

Red padlocks in form editor. This will not show padlock in rendered form.

当系统根据需要将其启用时，它将显示在编辑器中的字段标签旁边。尝试从表单中删除它们会给您消息。例如。合同模板，发给客户的账单等。

This will appear next to field label in editor when system enabled it as system required. Trying to remove them from Form will give you message. Eg. Contract Template, Bill To Customer, etc.

您要删除的字段是系统或企业所必需的。

The field you are trying to remove is required by the system or business.

当系统定制程序将特定属性锁定在 字段属性-锁定下时，表单编辑器中的字段会出现相同的红色挂锁。 code>。尝试从表单中删除该字段时说：

The same Red padlock appears for fields in form editor, when System Customizer locked that particular attribute under Field properties - Locking. Trying to remove that field from Form says:

您要删除的字段已锁定，无法删除。

The field you are trying to remove is locked and cannot be removed.

黑色挂锁以浏览器呈现的形式。该字段的控件在表单编辑器上显示为蓝色。

Black padlocks in browser rendered form. This field's control appears blue in color on form editor.

对于诸如CreatedOn，所有汇总字段，所有计算字段之类的系统字段，将出现。

For system fields like CreatedOn, All Rollup fields, All Calculated fields this will appear.

这将出现在字段属性-字段行为 下将字段设置为只读时，呈现时控件旁边的控件（文本框，查找）旁边。同样适用于禁用脚本的字段。

This will appear next to control (textbox, lookup) while rendering when the field is set as read-only under Field Properties - Field Behavior. Same applies to script disabled fields.

自动生成的ContractID，Currency，Originating Contract，Discount等字段将在创建记录后更改时被系统锁定没有道理。同样，这也会影响业务渠道。

Fields like auto-generated ContractID, Currency, Originating Contract, Discount will be locked by system as changing these after record creation does not make sense. Also this will impact the business pipeline.
