Capable Resources vs Implementing Resources

Hello,

I don’t quite understand the difference between defining capable resources on the operation and creating a link betweeen resource and operation. 

My goal is to have my resources visible for the particular operations in the work instructions (jigs etc.).

I’ve managed to do this with the Process Engineer role by defining the implement links between operation and resource with the Assignment Manager command. No capable resources are defined. And the assigned resources are visible in the work instructions with the assigned mfg items.

I’m trying to figure out, whether I can achieve the same thing by using MFN+MGA widget roles. But I can’t find a way to define those implement links between resources and operation in the widget apps. There is only an option to define capable resources and that does not seem to do the trick.

Does anyone have some idea how to go about this?
