Can EBS post to a cost center and income statement G/L Account?

I am trying to post directly to a cost center instead of using a clearing acct. The clearing acct is determined via user exit and acct modifier.

How would I post directly to a cost center?

Please see OSS note 494777 and 155596 for explanation of the function exit_rfebbu10_001 (enhancement FEB00001) for EBS processing... You might also want to reference OSS note 0124655 that describes supported functions of the EBS...

We use a custom "Z" table (this data is treated as transportable configuration) that contains our cost center values for posting to P&L accounts processed in EBS... this table supplies the values in the user-exit (above)...
