Conditional Stage Execution in EPM Pipeline

Hi,

I’m using EPM Data Integration → Pipeline and need conditional stages:

• At run time I pass a parameter (or pick from a list), e.g. A or B.
• If the value is A, a specific stage should run.
• Otherwise that stage should be skipped (rest of the pipeline continues).

How can I achieve the above?

I saw Stage Execution listed as a default variable on the Variables tab but couldn’t find documentation on whether it does this or how to wire it to individual stages.

Thanks.
