Assets Depreciation Expense Account, Expense account from assignment was selected

Hi There,

We are having a situation, when asset is depreciated and create accounting was run, we are observing that the Debit entries generated are being picked from Expense Account from Assignments. There are no SLA changes done for Event Depreciation, only seeded rules are used as listed below..

Journal Line Definition ->Assets Standard Accounting-All16,

Journal Line Type -> Periodic Depreciation Expense and

Account Derivation Rule – Assets Depreciation Expense Account.

I also notice in the Account Derivation Rule condition that there are 2 conditions

Priority 1 -> Generated Code Combination Identifier

priority 2 -> Expense Account Code Combination Identifier.

As mentioned above some how the first condition is missed and the expense account was picked. Not really sure why, Is this an intended behaviour to pick expense account? Can you please let me know the logic of deriving the Code combination for condition 1 (Generated Code Combination Identifier).
