Open the row definition used by the report being generated.
Go to Edit | Rounding Adjustment from the MR toolbar.
Note the row codes specified in this setup window and confirm they are as desired. Any rounding adjustment will be placed in the row code specified as the adjustment line. The values may be blanked out on this window to temporarily turn off the rounding adjustment. It can be helpful to do this and regenerate the report to get a more accurate view of the balances being included on the report and the out of balance. There could potentially be GL accounts that were recently added in SL and need included within the row definition of this report.
