Production Line - Discrete Job

Hi All,

As per the WIP user guide

"Production Lines:
You can define and update, but not delete, production lines. A production line describes a unique set of operations, departments, and/or manufacturing cells that produce one or more of your products.
You can associate production lines with repetitive assemblies, discrete jobs, and work order–less completions."

How can we associate a Discrete Job with a production Line?

Tried using the Associate Lines and Assembly. In this form, I cannot chose a discrete WIP class.

Any pointers on the same, do let me know.

Regards,

VN
