There you can see how many number of source rows are applied and how many number of rows loaded in to targets and how many number of rows rejected.This is called Quantitative testing.

If once rows are successfully loaded then we will go for qualitative testing.

Steps

1.Take the DATM(DATM means where all business rules are mentioned to the corresponding source columns) and check whether the data is loaded according to the DATM in to target table.If any data is not loaded according to the DATM then go and check in the code and rectify it.
