Currently when we view revenue information via the Corporate Structure process, we get different amounts when there is a write off.  

From BB support:

I received word from RDO that the Corporate Structure report and the Employee Information Individual Summary report were built with two different requirements in mind for the Giving Totals for Employees.

Currently, the functionality for these reports is as follows:

The Corporate Information > Employee information does not pull Write-off amounts from pledges. The Corporate Structure > Employee Giving is different because it also pulls in Write Off amounts from pledges.
