PO: Split Requisition Line/Distribution

[mjm]

We are running 12.0.4. My users are using iProcurement to enter a Req. with project information. I have a requirement to split the line (or distribution) into two lines (or two distributions on the same line). This should happen as part of the approval process. Has anyone done anything like this? I am looking for an API that I can call. Any suggestions?...
