SAP Standard extractor

Hello, i have a question about 2LIS_17_I0CAUSE extractor. I see that data comes from 3 tables like QMEL, QMFE and QMMA. i see a notification is in QMEL table but when i fill my setup table without any filters it leaves that one notification out. i want to know what type of filter is there for this extractor or what is the reason why that one notification is not coming to this extractor.

Thanks.
