Get invoice list

Question

Hi all
        I have come accross an anomaly while testing invoice list. The following is my code for getting the invoice list. The problem its that when i test it with customer no 1000 it displays invoice list of 1050 too. This happens ONLY for cutomer no 1000, testing with other entries gives the desired result. Is there anything that i am doing wrong w.r.to the coding part? Thanks

hard to read the code, but did you check to see if FOR ALL ENTRIES IN pt_customer_list  has rows in the PT_customer_list?  If you didn't I'd suggest a review of documentation of FOR ALL ENTRIES.  If you did make sure pt_customer_list isn't empty, then disregard.
