Hi,
1)Do I have to make REGION PLANT DELIVERY(WKREG) as navigational attribute to (0SD_C03 ) INFOCUBE?
if the above filed is enhanced in master data (ex: plant), then you can make it as navigational and use it to 0sd_c03, however, you have added a new filed in transnational data source structure,so you have to create a new info-object and then map WKREG to it.
however, the data source structure is changes, you have to delete the setup table , activate it, then unhide the new filed from RSA6 and replicate it to BW. If you want old/historic data then fill setup table and do full repair(assuming you will drop cube data) if you dont want to disturb delta .
2)since i din add navigational attribute from 0material so now , I have to delete the set up table?
Like I said in previous thread, adding/enabling navigational attribute in cube, doesn't required to refill setup tables..
