# Getting error message while creating a new user: 'The Username already exists in the system. Please try a different Username'

## Symptom

- When I try to create a new user, the system displays a message 'The Username already exists in the system
- Please try a different Username', indicating that the username already exists, even though I know there is no user with the same username in my company

## Cause

- SAP Fieldglass validates usernames globally. When a username is entered during user creation, the system checks the entire SAP Fieldglass database — across all buyers, suppliers, and workers — to ensure the username is unique
- If the username already exists in any other SAP Fieldglass account, even if it is not related to your company, the system will prevent the creation.

## Resolution

Use a different username that is not already in use in the SAP Fieldglass global database.
