Need different accounting for non-recoverable Tax than item expense

Summary:

hi,

For Leases in IFRS, there are short-mid-and long term accounting requirements. Means, when lease is booked originally, depending on duration of lease term, it needs to be reported differently. For this reason, our client has dedicated an item expense account for leases and would like to dedicate a separate account for non-deductable tax portion of those leases.

Currently in Oracle, Non Recoverable Tax will always take the Account Combination of Item Expense it relates to.

This means manual reclassification of booked lines which is a lot of work.

Does anyone have a more intelligent solution for accounting of the non-deductable tax, (much like you can have a dedicated account for the deductible part of the tax amount)
