I am doing setup in a new instance.
All the setups are complete in Purchasing but PO’s are not getting approved.
Even after clicking on the approve button system does not starts the approval WF and order shows as incomplete
Please check if 'owner can approve' check box is enabled or not
PO: Set up > Purchasing > Document Types
Check whether approver is there or not , if approver is there check approved level.
Take Own employee as approver
After completed all the employee setups, approve attributes and purchasing Hierarchy; run the request: Fill Employee Hierarchy
Request > Submit new Request Run > Fill Employee Hierarchy
