Missing delta records for the Z extractor

Question

Hi,
I have created a Z extractor for the table BUT050 in CRM. I have created a function module and have included the delta logic on CRDAT which is the created date, CRTIM - created time, CHDAT - change date, CHTIM - Change time. I have initialed the delta and started doing the delta loads. I found that there are few missing records in the extractor when compared to the table. I'm attaching my code below.Can anyone please look into it and tell me what the issue is.
