# Epicor Prophet 21 License and Domain, Manuals and User Groups > Source: https://netray.co/erp-help/epicor-prophet-21-license-domain-manual-user-group > Publisher: Netray (netray.co), AI and integration engineering for ERP and manufacturing systems. > Section: ERP Help ## Short answer Prophet 21 licensing is issued and managed by Epicor against your customer account and tied to your modules and user counts, so changes and renewals go through Epicor or your reseller. The word 'domain' can mean your Windows or Active Directory domain used for sign-in, or the P21 environment and server your users connect to. Documentation is delivered through Epicor's customer portal and in-product help, and user groups run through Epicor's community and events. ## Kind how-to ## System epicor ## Erp Epicor Prophet 21 ## Module Licensing / Administration / Community ## Query epicor prophet 21 license domain ## Alternate Queries - epicor prophet 21 user manual - epicor prophet 21 user group - prophet 21 license key - p21 documentation ## Applies To Epicor Prophet 21 (P21), on-prem and hosted ## Steps ### How to sort out license, domain and resources **Items:** - Clarify which 'domain' you mean: Windows/AD domain for authentication, the P21 server or database environment, or a web domain for the P21 web client and APIs. - For licensing, find your license details in the Epicor customer portal or from your account manager. Licenses are tied to modules and concurrent or named user counts. - If a user cannot sign in because of license limits, check the number of active sessions and whether stale sessions are consuming seats, then have an administrator clear them. - For authentication domain issues, confirm the user's P21 user ID mapping and that the server can reach the domain controller if directory sign-in is used. - For documentation, use the in-product help and the user guides on Epicor's customer portal for your version, and download the guide that matches your release. - For peer help, search the Epicor community forums and the user group channels, and attend the user conference sessions for distribution topics. - Contact Epicor support for license file or key issues. Do not share license keys on public forums. ## Sections ### Licensing basics **Body:** P21 licenses control which modules are enabled and how many users can connect. Because the terms are contractual and tied to your customer record, changes (adding modules, users, or moving environments) are handled by Epicor or your reseller. Moving the server or restoring a database to a test system may require a separate non-production license arrangement. I cannot give exact file names or screens for license import because they change by version. Your administrator guide for your release has the authoritative steps. ### What 'domain' usually means **Body:** Most often this question is about sign-in: users authenticate with their own P21 credentials or through a Windows domain account. Mismatches between the user ID in P21 and the directory account are the usual cause of 'cannot log in' tickets. A second meaning is the web address of your P21 services, used by integrations and the OData or middleware APIs. Confirm certificates and DNS names when you move servers. ### Manuals and user groups **Body:** Epicor publishes versioned documentation and training for Prophet 21 through its customer portal. Always use the guide for your running version, because screens and fields change between releases. User groups and community forums are useful for distribution-specific practice: pricing, rebates, drop ship and warehouse workflows. Treat forum advice as input to test in a non-production environment, not as a production instruction. ## Pitfalls - Using the guide for a different P21 version leads to missing fields and wrong menu paths. - Posting license keys or server names publicly is a security risk. - Restoring production to test without checking license terms may break sign-in or breach terms. - Stale sessions silently use license seats and block new logins. ## Ai Angle Many P21 questions are answered by reading manuals and your own configuration. A private assistant that indexes your P21 documentation, release notes and internal runbooks on-prem (Netray DataRay does this over local files) can answer 'how do we do X in our version' without sending documents to a public service. ## Faq ### What is the Prophet 21 license domain? **Answer:** The term is ambiguous. It may mean your Windows authentication domain, the P21 environment or the web domain of the services. Licensing itself is issued by Epicor against your account. ### Where is the Epicor Prophet 21 user manual? **Answer:** In-product help and the guides on Epicor's customer portal, by version. Download the one matching your release. ### Is there a Prophet 21 user group? **Answer:** Yes. Epicor runs community forums and customer events, and distributors form their own regional groups. Ask your account manager for current options. ### Who can change my P21 licenses? **Answer:** Epicor or your reseller, through your account. Your administrator applies the updated license in your environment following the guide for your version. ## Search terms epicor prophet 21 license domain, epicor prophet 21 user manual, epicor prophet 21 user group, prophet 21 licensing, p21 license seats, prophet 21 documentation, p21 sign in domain, prophet 21 community --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
