Official Self approval process in CfTE

Question

Issue:
Cost center Owner is submitting the Expense report and you have to restrict
him from approving his own Expense report.
Conclusion:
There is a scoping question in BC to allow or switch off Self-approval.
If Self approval is switched off then the approver receives the approval task in his Inbox but cannot approve,a self -approval error message prevents him.In this case he has to manually forward the task to another user.This is the Official Self approval Prevention solution for SAP Cloud for Travel.

Answer 1

Task assignment in SOA are done via human task assignment i.e. the .task component in BPEL. Now this task assignment can use various features to compute whom to assign the task to.
1. Static: This is when you specify the group name or the user name directly into the task.
2. Dynamic : This is when you assign the approver to be a variable and in your SOA workflow before task assignment you assign value to this variable.
3. External Routing: This is when you assign a java code inside the .task to do all the assignment and escalations. When using this you can have complex implementations done.
What I meant by looping is that you will need to call this .task two times, first time of the first approver and second time (if the first approves it) for the second approver. Thus when you are inside the loop you need to get the appropriate value from the payload (payload is sent from OIM to SOA when you submit/approve the request) and set it into the appropriate variable so that .task reads that variable and assigns the task to that person.
I would recommend going through the BPEL developers guide for better understanding. Start with a simple process and see how it behaves when it runs and then pile on top of it.
