HI,
if you the numeric pointers and if the changes in R/3 create a new record with a new numeric pointer which is different then the original record then it will get pulled as delta.
In numeric pointer option you can give the field name of the table which can be a any numeric or char field like document number.
If the posting is happening at the same time then depending upon the offset given it will come in the next load.
Thanks,
Phani.
