We have a few large charges that need to be split between multiple SubTowers based on a predetermined %. Any idea how to make that happen?  Anyone else encourage termed this?

Create a new object between your IT resource towers and the Other cost pool objects with a table that defines the % of each expense that goes to each subtower

One way to do this would be to use a Use Map Table.  Basically, you create a table that has the unique ID from the sending object, the unique ID from the receiving object and a weighting column.  Then, click on the Advanced allocation option (see below) and enter the following formula: =Use_Map_Table(table:weight_column[,source_column,target_column][,format)]

You can find more details by searching for Use_Map_Table function in your help section or talking to your Customer Success Manager.
