Diff between Full and Delta Init With data Transfer
I have enhanced the standard datasource with 2 new fields and moving to PROD,where Processchain for Delta load is daily getting loaded(without enhancements).Existing cube in Prod has 8 crores of records.
After ECC DS Transport,replicate to BW and BW objects Transport INCLUDING Datasource.
1.Delete data (I need historical dat for the enhanced field) from the cube,DO FULL LOAD and DELTA INIT WITHOUT DATA TRANSFER.
2.Delete Data,REPAIR FULL REQUEST without any filters,and run the existing delta process chains(delta will take care).
3.Delete Data,INIT With Data Transfer and run the existing delta process chains.
4.Run FULL IP,Delta init without data transfer and run the existing delta process chains.
Which option should I follow?is there any difference between full load and delta init with data transfer?
If you are sure that no posting would happen when you perform your Full load then there is nothing to worry.
you can do Full load -> initialize delta -> schedule PC for delta loads.
Say in case if there are chances of user posting some entries during the Full load, then you might lose those records which were posted duirng the full load(As per example above Full load occurs between 9pm to 10pm, if user post any data during these period then those will not be captured neither in the Full load nor in the delta load and you might end up losing those records.).
Hope it is clear for you now.
