There are several ways in which a warehouse management system UPWMS protects users from errors.
Some of the measures implemented to prevent errors in a UPWMS include:

1. Data validation: A UPWMS is configured to validate data as it is entered into the system to ensure that it is accurate and complete. This can help to prevent errors caused by incorrect or missing data, and can also ensure that data is consistent and conforms to established standards or rules.

2. Process controls: A UPWMS is configured to enforce process controls and checks to ensure that tasks are completed accurately and consistently.
For example, a UPWMS may require that certain steps be completed in a specific order, or that certain information be verified before a task can be completed.

3. User permissions: A UPWMS is configured to grant different levels of access and permissions to different users, based on their roles and responsibilities within the organization.
This is help to prevent users from accidentally making changes or performing actions that they are not authorized to do.
