Adjustments to Funds-Distributed Projects through the General Ledger

There are times that we need to make an adjustment or accounting correction to a project prospectively and do not want the adjustment to go through Funds Distribution.  We would like to do this through a GL entry that updates Project Costing, including the distributed amount. The goal is to make a correction and have that correction update the distributed amount so that we don’t have a problem with the threshold on the funds distribution rule.  We use the threshold for reporting so need to make sure that it remains accurate, as well as the distributed amount.

Is it possible to do this with an on-line entry into GL?  If so, which Analysis type should be used?
