how to find the unprocessed entries in the element entry page.

We have a requirement where we need to find the unprocessed entries, but the scenario is where the amount to be paid is not paid fully that means the amount has been paid partially because of that in the BIP report we used pay_event_relationships which has approval_status as C(Completed) so we were not able to find the unprocessed.

in the frontend element entry page it looks unprocessed but because of the partially paid amount it is showing C(Completed) in the BIP report output.

Can anyone please help me to resolve this issue.

Thanks in Advance.
