Business requirement to Skip the approval second time after changing some information in Invoice for specific invoice Source.  We have multiple approvals level in the system, (like 4-5 stages, it takes lot of time).

So business would like to skip the approval second time.

If there is any change in amount, it should trigger for approval. Business changes Account/Cost Center, Period (Multi period accounting case).

Pleas suggest best way to achieve this.
