The SAP error message
/SCWM/WM_SEL021 No resource selected
typically occurs in the context of SAP Extended Warehouse Management (EWM) when a user attempts to perform an action that requires a resource (such as a warehouse worker or a piece of equipment), but no resource has been selected or available for the operation.Cause:
- No Resource Assigned: The most common cause is that there are no resources assigned to the task or operation you are trying to perform.
- Resource Status: The resources that are available may be in a status that does not allow them to be selected (e.g., they may be busy, inactive, or not available).
- Selection Criteria: The selection criteria used to find resources may not match any available resources.
- Configuration Issues: There may be configuration issues in the EWM system that prevent resources from being recognized or selected.
Solution:
- Check Resource Availability: Ensure that there are resources available in the system. You can do this by navigating to the resource management area in EWM and checking the status of the resources.
- Assign Resources: If no resources are assigned, you may need to assign them to the relevant task or operation. This can be done through the resource management interface.
- Review Resource Status: Check the status of the resources to ensure they are active and available for selection. If they are busy or inactive, you may need to wait until they are free or change their status.
- Adjust Selection Criteria: If you are using specific selection criteria to find resources, consider adjusting these criteria to broaden the search and include more resources.
- Configuration Review: If the issue persists, review the configuration settings in EWM to ensure that resources are set up correctly and that there are no restrictions preventing their selection.

SAP messages fall into 3 different categories: Error messages
(message type = E), Warnings (W) or Informational (I) messages.
An error message will prevent you from continuing your work - it is a hard stop and you need to fix the error before you can proceed. A warning message will stop your work, however, you can then bypass the warning by pressing the Enter key on your keyboard. That said, it is still good practice to investigate the cause of the warning message and address it. An information message will not stop your work and is truly just for informational purposes.
