Loading flat files with "Additive Delta"
Whiles loading flat files with "Additive Delta"
following describes the scenario:
Suppose there is flat file containing data:
I will initialize delta selecting "Additive Delta" Option in infosource transfer structure and create ODS with these fields and create update rules and then load infopackage with initialize delta option and load the data.
Now i will change the flat file as every thing same as above but "Quantity will be changed to 8".
then with delta options i load data and no doubt i got the changed ones only...
But According to additive delta concept it is like this : first initialize with delta taking the old file and later load with delta with the another file taking quantity as -2 (so that it results like:+10-2=8).
How to achieve this ? is it possible?
instead of loading with 8 i will load it with -2...will it reflect and give me 8? (+10-2=8???)
Thanks & Regards,
