You may see the following error when planning a works order:
Order code [order code]
Error in process definition, process [process name] Resource [resource name] Same resource relationship type cannot be used on multiple capacity resources. Remove the same resource marker from the dependency with op 2 or remove the task overlaps option on the resource [resource name].
Why this happens
This error occurs because Allow Task Overlaps and Same Resource are switched on at the same time on a multi-capacity resource. These two options are not compatible with each other.
A multi-capacity resource is one where the units available is 2 or above. This applies when:
You click Edit from the Resources menu and the units available is set to 2 or above.
A labour resource has a quantity adjustment higher than 1 from the default shift pattern assignment.
The Same Resource relationship type can only be used on a resource with a maximum of 1 unit available. Same Resource tasks cannot be assigned to a resource where Allow Task Overlaps is ticked and the units available is 2 or above.
Resolution
To resolve this error, you need to do one of the following on the relevant process or resource:
Remove the Same Resource marker from the dependency on the relevant process operation step.
Remove the Allow Task Overlaps option on the resource mentioned in the error.
📌Note: Same Resource tasks can be assigned to resources where Allow Task Overlaps is not ticked, regardless of the number of units available.
