API Incremental Backflush - Ignore Exception still erroring out

Hi friends.

I'm developing together a friend a customization which calls the API gme_api_pub.incremental_backflush.

We are passing the parameter p_ignore_exception as FND_API.G_TRUE because we know sometimes the process won't have enough ingredients to backflush and the requirement is not stop the process and yield the product anyway.

The problem is, even passing this parameter we are gettting these errors:

E - Incremental Backflush is completed with material exceptions.

E - All records failed after line validation

E - Quantity must be less than or equal to Available to transact

Retrieving a debug file from server we found the error in the line:
