Workflow Background process not picking up deferred requisition approval

Morning,

I have created a New Entity on our test instance, new Busines Group and Operating Unit  and everything. I am testing requisions through iproc, and the requision approval stays in deferred 'waiting for background process'. I have run the background process manually, and it does not change. Is there a way that I can see why it is not picking up my requisition?

if I want run the background process for specific item types, I dont see a requisition approval item type, only PO Approval? Is that for requisitions?? The only requisition item type is just plain 'requisition' on its own.
