Working with Custom Fields

In Zoho CRM, you can add new fields as per your requirements. These fields will be available to all the users added to your organization's CRM account.

  • Customize Zoho Defined Fields: You can edit, delete and hide some of Zoho defined fields, but note that there are some fields that you cannot delete, remove, rename or change from mandatory settings. These Zoho defined fields are mandatory in Zoho CRM. For example, Last Name in Leads, Subject in Tasks etc.

Note
  1. Custom fields are not available in the Free edition of Zoho CRM.
  2. Lookup and Formula fields are not available in the Standard Edition of Zoho CRM.

Custom Field Settings

On adding or editing a custom field, you will be able to accomplish a bunch of actions on it. For example, you can edit a field's basic properties, mark it as required, make it a unique field and so on. Following are the various custom field settings that are available in Zoho CRM.

  • Add Custom Fields
  • Edit Custom Fields
  • Set Field Permission
  • Mark a Field as Required
  • Mark a Field as Unique
  • Set External Field
  • Remove/Delete Custom Fields
  • Map Dependency Fields

Add Custom Fields

In each module, you can add custom fields to capture important data specific to your business requirements by specifying some field-related information.

To create new custom fields

  1. Log in to your Zoho CRM account with Administrative privileges.
  2. Go to Setup > Customization > Modules and Fields.
    Module refers to the Leads, Accounts, Contacts, etc. tabs.
  3. Click the desired module to open the layout editor.
  4. From the New Fields Tray on the left, drag and drop the required field type into the desired module section on the right.
  5. Name the field and define the Field Properties as required for the field.
  6. Click Save Layout.
Note
  1. The [Module] Name field of a custom module can be renamed whereas the [Module] Name field of a pre-defined module cannot be renamed.
  2. In the case of the Name field for a custom module, the user can choose between the field types, Text and Auto Number. Once chosen, the default Name field type cannot be changed.

    Also, if the Name field of the custom module is an Auto Number field, the respective module cannot have any other Auto Number field as only one Auto Number field is allowed per custom module.
    Existing custom modules cannot have the Auto Number as the default Name field. So a work-around would be to create a new custom module and choose Auto Number as the Name field type and then import the existing records.
  3. Once the field is created, you cannot change the 'data type' of the field. For example, an Integer (digits) field cannot be changed into a Currency field.
  4. You can edit the custom fields to change the length of the following types of fields. - Currency, Text, Number (Integer), Decimal, Phone, Long Integer and URL.
  5. You cannot add custom fields in the Log a Call page. However, you can customize the existing fields using page layout customization.
  6. The Also create for Accounts, Contacts, Deals option will be available only while creating fields for Leads.
  7. The Also create for Sales Orders, Invoices option will be available only while creating fields for Quotes.
  8. In the picklist field type, you can enable the history tracking of a particular field. See also: Picklist Tracking History
  9. In case the picklist field value is translated, you can use the Reference Values to define the custom functions, merge fields, formula fields, and so on. Learn more about reference values in Translations
  10. In the Picklist field for Meetings module, you can associate color to each picklist value. These colors will be shown across calendar, related lists, reminders, home page, list view etc.. Read more about Pick List Fields

Edit Custom Fields

To edit custom fields

  1. Log in to your Zoho CRM account with Administrative privileges.
  2. Go to Setup > Customization > Modules and Fields.
    Module refers to the Leads, Accounts, Contacts, etc. tabs.
  3. Click the desired module to open the layout editor.
  4. Go to the field you want to edit and rename the field or edit the Field Properties.
  5. Click Save Layout.


Set Field Permission

You can set the different field permissions for different users when you create a field or even at a later time.

To set field permission

  1. Log in to your Zoho CRM account with Administrative privileges.
  2. Go to Setup > Customization > Modules and Fields.
    Module refers to the Leads, Accounts, Contacts, etc. tabs.
  3. Click the desired module to open the layout editor.
  4. Go to the required field, click the Settings icon and select Set Permission. 
  5. In the Set Permission popup, define the permissions for each profile.
  6. Click Save.
  7. Click Save Layout.

Mark a Field as Required

To mark a field as a required field

  1. Log in to your Zoho CRM account with Administrative privileges.
  2. Go to Setup > Customization > Modules and Fields.
    Module refers to the Leads, Accounts, Contacts, etc. tabs.
  3. Click the desired module to open the layout editor.
  4. Go to the field you wish to edit, click the Settings icon and select Mark as required. 

Mark a Field as Unique

A unique field is that field in a record whose value makes the record unique. Email addresses of people are good examples of unique fields because clearly, two people cannot have the same Email address. It is a very unique attribute. Other examples include Social Security Numbers, Passport Numbers, Product codes and the like. In Zoho CRM, you can mark a field from any module as "Unique". Once marked as "Unique", these fields play a vital role in managing duplicate records in Zoho CRM in various instances including manual creation of records as well as records created via import, APIs, lead/sales order/quote coversion.

To mark a field as unique

  1. Log in to your Zoho CRM account with Administrative privileges.
  2. Go to Setup > Customization > Modules and Fields.
    Module refers to the Leads, Accounts, Contacts, etc. tabs.
  3. Click the desired module to open the layout editor.
  4. Click the Settings icon on the field that you wish to mark as unique.
  5. Select the Do not allow duplicate values option from the Settings drop-down list.
    This option is applicable if the field that you want to mark as unique is a predefined field.
    Marking the Primary Email field for the Leads/Contacts module as unique will ensure email duplication check for the selected module.

    If the field you wish to mark as unique is a custom field, then select Field Properties from the Settings drop-down list.
    In the Field Properties popup, select the Do not allow duplicate values checkbox.
  6. Click Save Layout.

In the Fields List View page, under the Data Type column, the field for which you have selected the Do not allow duplicate values option will be indicated as a Unique field. For example, Text (Unique).

Note
  1. The Unique Fields feature is available only in the paid editions of Zoho CRM.
  2. Only users who have the Customize Zoho CRM Permission enabled in their profiles will be able to mark a field as unique.
  3. A module in Zoho CRM can have 2 unique fields. Following are exceptions to this condition, as they can have 3 unique fields.
  4. Leads/Contacts/Custom modules (Email address + 2 fields)
  5. Products module (Product Code + 2 fields).
  6. Only Text, Email, Phone, Integer, Long Integer, URL fields can be marked as unique across all modules. The Twitterfield can be marked as unique for the Leads/Contacts module.
  7. The unique fields are NOT case sensitive. That is, if the incoming unique field's value is "ABC" and in the existing record, it is "abc", Zoho CRM will still identify this as a match.
  8. Once a field has been marked as unique, it may take a little while for Zoho CRM to index this change in the database. That is, after marking a field as unique, if you immediately create a record in the module with the same value, Zoho CRM may not recognize the unique field value. It may allow the duplicate to be created, because the change has still not been indexed. In such a case please try after a few minutes.
  9. Task, Calls and Meetings (Activities) modules cannot have a unique field.
  10. In Zoho CRM, unique fields are supported for records that are created manually and via imports, APIs and leads/quotes/sales orders conversion.
  11. Unique fields are not supported for records that are created via CRM migration, MS Outlook and Google synchronization, restoration from the Recycle Bin.
  12. Unique fields are not supported for records in the Zoho Sheet View.
  13. When you mark a field as unique in the Leads module, you will see an option to enable duplication check for converted leads as well.
    Consider a scenario. You have followed up with and converted a lead called James. Now James is record in the Contacts module. Another sales rep in your team adds the same lead (James), without knowing that the lead has already been followed up with. In that case, there is no need for James to be added as a lead again - it will simply be a duplicate entry.
    In this case, you can stop the creation of the same lead by enabling duplication check for converted leads. Once you have enabled this, whenever a duplicate entry is added in Leads, CRM will check existing leads as well as converted leads for matches. 

    To enable Duplication check for Converted Leads, click the Change Preference link, which appears when you mark a field as unique. In the Duplicate Check Preference popup, select the Check duplicates on converted Leads alsocheckbox and click Save. You can always change this setting later. 
    You can also enable duplication check from Settings > Setup > Customization > Modules > Leads. Click the More icon on Leads > Duplicate Check Preference.

Set External Field

A custom single line field can be marked as an external field where information about the record from a third-party application can be stored. When you integrate an application with CRM you can upsert API call to search, create or update, and delete records using the external ID.
For example, if the patients IDs are stored in an external database you can use it in the external field to refer, update or delete details in CRM.
Similarly you can use other fields that refer to the patient's records as well.
There are two types of external fields:
  1. User based: A different external ID will be generated for each user. For example, if a contact is managed by two different users in the org, each one will have his own external ID for the same contact.  
  2. Organization based: All the users in the org will have a common external ID.  
To set a field external or to create an external ID
  1. In the module builder, drag and drop the single line field.
  2. Click Edit Properties and select Set External Field.
  3. In External Field Type select Organization or User.
  4. Select Field visibility as Show or Hide.
  5. Click Done.
      
Note 
  1. While performing Find and Merge action, the external ID of the master record will be retained, that is the external ID of other duplicate records will be overwritten.
  2. When a record is cloned the external ID will not be copied to the new record. You can later update the value in the field (external ID) through API.
  3. During the conversion of a record such as lead, orders, quotes etc. you will be allowed to map an external field only with another external field present in the subsequent module.
  4. During data import any field present in the .CSV file can be mapped with an external field present in the CRM module. The value of the external ID field can be updated only through API.

Remove/Delete Custom Fields

The fields that you have created can be removed, in case you do not need them. When you remove a custom field, it is moved to the Unused Fieldssection. This means that it is only removed from the layout and not the CRM itself.
To delete the field permanently from the CRM, you must delete it again from the Unused Fields section.

To remove custom fields from the layout

  1. Log in to your Zoho CRM account with Administrative privileges.
  2. Go to Setup > Customization > Modules and Fields.
    Module refers to the Leads, Accounts, Contacts, etc. tabs.
  3. Click the desired module to open the layout editor.
  4. Click the More icon and select Remove Field.
  5. Make sure to read the instructions in the pop-up box and then click Yes, move to unused fields to remove the field.
    The removed fields are pushed to the Unused Fields section.
Note
  1. When a custom field is moved to the Unused Fields section, it is only removed from the module's layout and not Zoho CRM. As long as the removed field is in the Unused Fields section, you can restore it by dragging and dropping it back in the required section.
  2. Restoring a field from the Unused Fields section restores its associated data as well.
  3. When a removed field is in the Unused Fields section, it is still part of the database. Therefore the total number of fields allowed for your Zoho CRM Edition includes the fields in the Unused Fields section.
  4. To delete a custom field permanently from Zoho CRM, you must delete it again from the Unused Fields section.
  5. Once deleted from the Unused Fields section you cannot bring back the custom field and its associated data.
  6. Standard fields that are provided in Zoho CRM by default can be moved to the Unused Fields section but cannot be deleted permanently.

Map Dependency Fields

Map Dependency is available for the picklist fields present in the Subforms too. 

There are certain fields whose values depend on another field's value. This can be defined as a parent-child relationship. For example, let's say there are two fields - Country and State - in your Leads module. The values in the State field will depend on the country that you select from the Country field. Similarly, the values for the Sub-Department field will depend on the Department field that you select. This kind of relationship is established by mapping dependency fields. You can define which values will appear in the Child field when a certain value is chosen in the Parent field.

Note: The parent and child fields will display all the picklist fields present in the layout and subform. 

To map field dependencies

  1. Log in to your Zoho CRM account with Administrative privileges.
  2. Go to Setup > Customization > Modules and Fields.
    Module refers to the Leads, Accounts, Contacts, etc. tabs.
  3. Click the desired module to open the layout editor.
  4. Click the Settings icon and select Map Dependency Fields.
  5. In the Map Dependency Fields page for the selected module, click New.
    • Select the Parent Field from the drop-down list.
    • Select the Child Field from the drop-down list.
    • Click Next.
    • Select the values for each parent field value.
    • For example, if the parent field is Branch of Studies, then, select the Courses relevant for the selected branch.
    • Click the Previous or Next links, if required, to map the all the Parent field values to the Child field values.
  6. Click Save.
    Now when you create a new record in the module, the values on the child field differ based on the value chosen for the Parent field.
