Oracle PeopleSoft- Travel and Expenses - Rounding Rules for Split Distributions

Hello,

What are the Rounding Rules for travel and expenses (Oracle PeopleSoft) when there are multiple distribution lines/split?

My organization is currently on Image 41 (Tools Release 8.59.04). I have a question about rounding, specifically in the travel and expense module in Oracle PeopleSoft. In our organization we have speecharts that may have multiple distribution lines and/or splits. For example, we may have employees whose distribution split may be 90/10, 90/5/5 etc. We also have Agencies where the distribution split may be 86/5/2/2/5.

We are trying to determine how the system rounds values for travel and expenses. Is there a specific formula or code that the system utilizes? If so, where can I locate this information. I have seen where the system may add a penny (0.01) to the second row of the distribution and remove the penny from the 4th distribution line. How does the system decide which row to increase and/or decrease due to rounding when the amount is a penny or 2 (0.01 or 0.02) off?
