Addition Event Class

We have quirky scenario here.  In Mass Additions an line is brought in with 3 units and split.  After the split and before posting, the cost of each of the assets is adjusted.  The total of all 3 still equal the priginal cost.  We thne post the asset and run creat accounting.  A journal entry with the event class Additions, event type Additions fails.  Below is the journal it si trying to create:

Debit Asset Cost                           500                         Adjusted cost of the asset

Credit Asset Clearing                               525             Original cost of the split line

Debit?????                                     25                         Adjustment amount 

From partial account string given with the error, it looks as though it is trying to use a clearing account.  Is it from a diffferent event class, Adjustment????
