Hello, @Huma Naaz2 , I facing the same kind of issue, State is changing to scheduled when we click on request approval UI action in SOW and can see work flow ia getting attched by skipping all the conditions and approval process,  but working as expected in Default view

1. I  customized normal change work flow on change policies and approvals in default view and  it is working as expected in default view,

customizations

1. If conditions 

2. peer review process based on assignment groups

3. Percentage of approvals in change policies

2.. When tested in through Service operational workspace, change is moving to scheduled state after clicking on 'Request approvals' UI action , when i see the additional details tab in sow, it shows change policy's attached but no approvals triggered.

3. When i checked the workflow it is skipping the change policy's and moving to scheduled state

4. Thought of removing 'New change request ' option in SOW but end up with how to guide user to change management from SOW, like UI action which directs to default view .
