RE: Unapproved invoices report
You can check this report in AP > Inquiries and reports > Invoice > Invoices not approved report.
However; I think this topic was discussed before in this forum. Don't remember the subject line of that thread.
Anyway.. for all type of documents, if you want to see the work item is pending with whom and since when; then you can refer to the Workflow history report in Organization Administration module.
Take help of developer to add columns to display relevant details in this report.
I had the same requirement from one client for which we didn't touch the standard "Workflow history" report. Instead; we delivered a new customized report, almost same as workflow history report but added few new columns as required by them.
Details you can pick from workflow history of the document (journal, PO, PR etc..) and explain the developer. That's it.
Attached is the report we developed.
