An app builder has created a new report type but users are unable to select it from the Report Type list when making a new report for records they…

When a new custom report type is created in Salesforce, its default status is "In Development." In this state, the report type is only visible to and usable by administrators and users with the "Manage Custom Report Types" permission. To make the report type available for all other users to select when creating new reports, an administrator or app builder must explicitly change its status to "Deployed." The scenario described, where users cannot see a newly created report type, directly points to it not being deployed yet.

A. Access to the necessary object is unavailable.

While lack of object access can prevent a user from seeing a report type, the question states users are reporting on records they own, which implies they have access.

B. The report type is in a status of Deployed.

A "Deployed" status is what makes the report type visible to users. This is the required state, not the cause of the problem.

C. Access to Create and Customize Reports is disabled.

If this permission were disabled, users would not be able to initiate the report creation process at all, rather than just being unable to find a specific report type.

1. Salesforce Help, Manage Custom Report Types:

Reference: Under the section "Edit a Custom Report Type," the documentation states: "When you create a custom report type, it has a status of 'In Development.' When you’re ready to let your users create reports from it, deploy it." It further clarifies, "Report types in development are only visible to authorized administrators..." This directly supports that an "In Development" status (Option D) is the cause of the issue.

2. Salesforce Help, Considerations for Custom Report Types:

Reference: This document outlines visibility rules, stating: "To see a custom report type in the report wizard, a user must have 'Read' access to the primary object and all objects that have a 'with' relationship to the primary object in the report type." While this supports the logic for option A, the most common and direct cause for a newly created report type being invisible is its deployment status, which acts as a primary gatekeeper before object-level permissions are even considered for end-users.

3. Trailhead, Reports & Dashboards for Lightning Experience, Create Reports with the Report Builder:

Reference: In the "Create a Custom Report Type" unit, the process of creating and deploying a report type is detailed. It implicitly and explicitly shows that deployment is the final step to make a report type available for general use, reinforcing that a non-deployed ("In Development") status prevents user access.
