I have a situation where I need to bring new master data into BW. The only way I have to bring these new fields is by customizing/enhancing extractor 2LIS_11_VAHDR. But the rest of my data flow is reading data using 2LIS_11_VAITM. in other words, I need to to get new data into 0SD_O02, I need to look it up from 0SD_O01 filled using the enhanced extractor (2LIS_11_VAHDR).
1) since I already have data in target (0SD_O01/0SD_O02), do I delete everything and full load or use Full Repair request 0SD_O01 / 0SD_O02
2) to bring the missing data 0SD_O02 which feed the rest of data from I need to look up data from 0SD_O01. Does this lookup be done in transformation using read from DSO or it must be done in Start/End routine?
Thanks for your help.
