Why do you need this change?

We are currently working on an upgrade project and implementing the MRP system. For this, we need to influence the planning behavior during the SKU loop iteration.

Specifically, we need to adjust prioritization between demands and supplies within the loop, which requires controlling the planning state dynamically.

At the moment, the parameter NextState in the publisher OnPlanItemOnBeforePlanThisSKULoopIteration is passed by value, which prevents us from modifying the planning result within our extension.

By changing NextState to a var parameter, we would be able to adjust the planning state dynamically in a clean and supported way, without modifying standard code.

This is a minimal and non-breaking change that improves extensibility and aligns with common patterns in Business Central.

If possible, we would highly appreciate having this change already in BC27, as it is required for our current project timeline.
