List of Documents to be cleared through MRKO

Hi Experts,

I have a requirement where the user wants a report to display all the documents that can be settled by MRKO. So I need to have a criteria to select such documents so that they can be listed. Can anyone please help me inform the criteria? I know that the PO for consignment needs to have item category as K and the movement for goods movement as 411. But I need to list the documents posted by MB1B. So how can I have this selection?

Thanks and Regards,
