# Epicor: No Employee Attached to User, Supplier Not Approved, Serial Mask Tokens > Source: https://netray.co/erp-help/epicor-no-employee-attached-to-user-supplier-not-approved > Publisher: Netray (netray.co), AI and integration engineering for ERP and manufacturing systems. > Section: ERP Help ## Short answer "No employee attached to user" means the signed-in user account is not linked to an employee record in that company, so shop floor and time entry screens cannot identify who is working. Fix it by linking the user and the employee. Supplier-not-approved errors come from approved supplier settings, and serial mask tokens are configured on the serial mask setup used by the part. ## Kind error ## System epicor ## Erp Epicor Kinetic ## Module Setup / Security / Purchasing / Serial Tracking ## Query epicor no employee attached to user ## Alternate Queries - epicor supplier not approved for operation - epicor kinetic create serial mask tokens - epicor user not linked to employee ## Applies To Epicor Kinetic and Epicor ERP 10; exact field locations can differ by release, so verify on your screens ## Steps ### How to fix these three setup errors **Items:** - For no employee attached to user: open User Account Maintenance and Employee Maintenance for the company you are signed into and check the user is linked to an employee record. - Confirm the employee is active and belongs to the right company and site, because the link is company-specific. - Sign out and in again, then retry the shop floor or time entry screen. - For supplier not approved for operation: open the job operation or purchase setup and check the supplier is on the approved list for that part, operation or outside processing. - Either approve the supplier in the supplier or part approved list setup or choose an approved supplier, following your quality procedure. - For serial mask tokens: open the serial mask setup used by the part's serial number format and review the tokens and their order. - Create the mask with the tokens your numbering needs, assign it to the part's tracking settings, and test with a new serial number. - Document each change, since these are quality and control settings. ## Sections ### No employee attached to user **Body:** Many shop floor programs record labour, so they need to know which employee a login represents. If the link between the user account and an employee is missing, the program stops with this error. It is common for new hires, for users added by IT without an employee record, and in a new company after a copy. The fix is administrative: make sure the employee exists, is active, and is linked to the user in that company. Because employees are company-level data, a user may work in company A and fail in company B. ### Supplier not approved for operation **Body:** This is a control, not a bug. The system is preventing a purchase or outside processing from going to a supplier who is not approved for that part or operation. Quality teams use approved supplier lists to enforce this. Do not remove the control to clear the error. Get the supplier approved through your process, or pick an approved one. If the supplier should have been approved, the fix is in the approved supplier setup rather than the job. ### Serial mask tokens **Body:** A serial mask defines the format of serial numbers using tokens for fixed text, counters, dates and other parts. The mask is then used by parts that are serial tracked. If tokens are missing or in an unsupported order, generation fails or produces a format you did not intend. Design the mask on paper first, including how it resets and how long it can be. Test with a non-production part and a handful of serial numbers before applying it to live inventory. ## Pitfalls - Linking users to employees in one company and expecting it to work in another. - Removing the supplier approval requirement to clear an error. - Changing a serial mask on a part that already has serials in stock without a plan. - Creating inactive or duplicate employee records. - Not documenting changes to quality controls. ## Ai Angle An assistant that can read your user, employee and supplier setup can list users without an employee link, or show which suppliers are approved for a part, so a support person can answer in minutes. With ERPray this is a read-only question with the query shown, and any fix stays an administrator's decision. ## Faq ### What does no employee attached to user mean in Epicor? **Answer:** The login used is not linked to an employee in the current company, so screens that record labour or time cannot identify the person. Link them in the user and employee setup. ### Why does it work in one company but not another? **Answer:** Employees are defined per company. A user linked in one company must also be linked in each other company where they need those screens. ### How do I resolve supplier not approved for operation? **Answer:** Approve the supplier through your approved supplier process for that part or operation, or choose a supplier that is already approved. Do not bypass the control. ### How do serial mask tokens work? **Answer:** A mask is built from tokens that represent fixed text, counters or dates, defining the serial number format for parts that are serial tracked. Test on a non-production part first. ## Search terms epicor no employee attached to user, epicor user not linked to employee, epicor supplier not approved for operation, epicor approved supplier list, epicor serial mask tokens, epicor kinetic serial mask, epicor employee maintenance, epicor user account maintenance --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
