What is Global Picklist ? And Why do we use it in Salesforce?

Hello Shariq,

A custom picklist is tied to a particular object as a field on the object. Unlike a custom picklist field, a global picklist exists independently as a global picklist value set. Its values are shared with any picklist that’s based on it.

A global picklist is a restricted picklist by nature. Only a Salesforce admin can add to or modify its values. Users can’t add unapproved values, even through the API.

From Setup, enter Picklist in the Quick Find box, then select Picklist Value Sets.
Next to Global Value Sets, click New.
Enter a label for the global value set. This name appears in Setup, and when users create a picklist based on this global value set.
To tell users what these values are for, enter a specific description of the global value set. This text appears on the Picklist Value Sets list page in Setup.
Enter the values, one per line.
Optionally choose to sort the values alphabetically or to use the first value in the list as the default value, or both. You can’t change these settings later.
If you select both options, Salesforce alphabetizes the entries and then sets the first alphabetized value as the default.
Click Save.

Your global value set is ready to be used in custom picklist fields. You can reorder the values by clicking Reorder.

Salesforce provides a way to create a custom Picklist on any Object or modify any existing Picklist values. But such type of Picklist is limited for that particular object and no other objects. Salesforce provides a flexibility to use “Global Picklist” value sets to share values across objects and custom Picklist fields and to restrict the Picklist to only the values that you specify.

A global Picklist value set is a restricted Picklist by nature. Only a Salesforce administrator can add to or modify its values. Each value set can have total 1000 values including both active and inactive and each salesforce org can have 500 global Picklist value sets.
Thus, we can create a Global Picklist value set to specify Org wide common details like Country codes, business product specific properties which can be shared by any other object in the Org.

Thanks
