SAP: CJI5. How does the system determines open POs?

Dear all,

I like to ask.

On what conditions does an entry appears in the CJI5 report for open POs.

I have been reading on the internet that as long as Goods Receipt has been performed, the open PO line item will not be displayed.

Are there any other factors implicating it? Example, Invoice Receipt, Goods Receipt amount, Delivery Complete indicator.

Please advise.

Thanks,
Taylen
