What can be modified on standard object fields?

The ability to modify standard object fields in Salesforce allows for customization to meet specific business needs. Focusing on the capability to change Help text for standard object fields, this feature provides guidance for users regarding the purpose and use of the field. Help text can enhance the user experience by clarifying what is expected to be entered into the field, making it particularly useful for ensuring data accuracy and consistency.

Other types of modifications to standard object fields are more restricted. For instance, while labels and default text may sometimes be customizable depending on the Salesforce environment, field types and picklist values in standard fields are typically immutable. Standard object fields come with pre-defined attributes that are integral to the system's functionality, leading to stricter limitations on what can be changed compared to Help text, which is specifically meant for user support. This aspect of modifying Help text makes it a practical tool for tailoring standard objects to suit specific organizational requirements while adhering to the foundational structure of Salesforce data models.
