HI guys
i am trying to develop a delta capable FM Extractor , my question is can some one give me some basic info on how it works.
what i know is in R3 when the user enters certain info it gets updated in some tables in R3. what i dont understand is how would i know that this transaction is a new record. , what logic do i use in the FM to pickup only changed records from these tables. i understand there are some fields that give u new image or old image distinction. where do i get those from.
secondly how does the bw side track the delta pointers where is that info stored. if i init load a cube or oDS today in bw when i run delta next time how will the cube know that it needs only new data.
thanks
