Delta records are missing for 2LIS_13_VDITM data source

Hi all,

Am using 2LIS_13_VDTIM and 2LIS_13_VDKON data source.

Have taken downtime, filled setup table and pulled full data to BW and initilized delta.

After 2 weeks  i ran my delta infopakage and was continuing daily with my delta run daily at morning 9 o'clock.

But later noticed that the delta records are missing and most of them are cancelled invoices.

No clue why the records are getting missed out.

Please let me know if any way to slove/handle this issue.

Thanks,

Malathi
