We see Other Work showing on Staffing Plan but not on the new Staffing Module.
Is this working as designed?
Yes it is working as designed.
The Staffing Plan was the original module for staffing in MUX and includes Other Work.
As more functionality was introduced, especially with Custom Investments, the idea is to move away from Classic Other Work and use the Custom Investments instead.
Release : 16.0.1
Component : Clarity Resource Management
If you want to see Other Work for the Staffing, use the Staffing Plan instead or move Other Work items to Custom Investments.
