2LIS_02_SCL get repeat records when extracting

Hi.experts:

I encounter a problem that 2LIS_02_SCL extract repeat records on REVERSE IMAGE,and then I get over 10 000 records about one purchase order,which has just one order item and 4 schedule item.

I use AFS in my system,who can help me about this?

Your quick response will definitely get high points.
