I am trying to make a generic extractor -delta enabled.
i am confused about this --<b>upper limit and lower limit </b>in saftey interval.
for <b>time stamp, numeric pointer, date</b> fields.
could anyone kindly explain me what r these upper limit and lower limit and how they work in regarding this three field types.
i even read hw to generic delta document. but i got stuck with these two --terms.....
plz explain me in simple language. plz ihave even read in help i could only understand about saftey interval but not about upper limit and lower limit.
thanks and regards.
Let me take an example of GL data extraction for explaining upper limit and lower limit.
Assume that I am extracting GL financial documents and have already extracted data till 10 Nov 2005.
Now if the upper limit for extraction of GL data is 1 that is till previous day.
The next time when I extract data the lower limit will be all GL documents posted subsequent to 10 Nov 2005 and the upper limit would be all documents posted till 16 Nov 2005 i.e. till the previous day, assuming that the data is being extracted on 17 Nov 2005.
In FI there are certain tables BWFI_AEDAT, BWOM2_TIMEST, BWFI_AEDAT which help keep track of change documents.
Moreover you could also do the setting for the parameter
BWFISAFETY in the table BWOM_SETTINGS
for maintaining the settings for delta safety.
I am not very sure how the same could be used in the Generic delta, but just to give you an idea.
Hope it helps.
