Data Loader is not showing up the field for mapping . I checked the field accessibility and the field is read only. Why is the field not available for mapping?

  • What operation are you performing? What field is it? Please edit your post to be more specific.

  • Did you just modified the Field Level Permissions (After Login into the Data Loader), If yes, then you need to log out and login again.

  • You can't map into read-only fields. They're read only.

    @Sumanth You need to make the field editable for your profile, then log out of the data loader and log back in to the Data Loader.

The Data Loader won't allow read-only fields to be mapped. Make sure the field is editable to the user's profile. If you change field permissions, you need to log out of the Data Loader and log in again.
