AUC disposal

HI Experts ,

We have couple AUC from Investment measure module and business want to dispose them without hitting FI . According to my experience is not possible .

we have only 2 options I BELIEVE

1) Reverse the settlement and post back to internal order and then write off .

or

2) settle to Final asset and change Dep key to 0000 and then scrap.

Do we think we have another solution .?

Many Thanks

Regards
