How to update xla trial balance tables after changing accounting class assignments

Hi All,

I would like to modify the report definition for Open Account Balance Listing (AP, AR) to track also the Tax account class and accrual (AP only). I have modified the corresponding 'Post-Accounting' programs by adding  new 'Accounting Class Assignments'.

Is there a way to make this change working also for past periods, so the report will show the Tax accounts for past periods as well? As far as I understand the XLA trial balance tables are populated when data is sent go GL only?

Regards,

Maciej
