Business Process LOV in Debrief

People,

In what business case is there a need for the business process LOV at the debrief form?

I mean, one can choose any business process defined in the system, but why would you allow a choice? The SR type is connected to one Business Process that is linked to all allowed SAC's and billing types. By allowing the choice of a business process you allow the engineer to debrief whatever he wants, not debrief what you have defined within the borders of the business process.

From my perspective there is enough flexibility in defining different SAC's.

There's probably a reason. Could you/anybody shed some insight?
