Hi experts,
I have created a customized BO with approval process defined. Currently, I have 3 problem with this.
1. I have errors while submit the instance to approval as below. The error message is "Process definition exists with configuration error Task type exists with instantiation lock"

2. I tried to modify the approval process, but the system prevent my changes with errors. "Cannot maintain the process; Instantiation lock is set for task type YI676K31Y_APP2_APP"

3. If I want to have a multi choices in the work distribution dropdown box, just like what we have in the Approval Process for Contract like below, how to achieve this?

Thanks for your help.
