Hi Srikanth,
Pls check the below points
1. Thru t code - LISTCUBE, check the data, newly loaded data was visible or not.
2. Check cubes (which are connected thru Multiprovider), Right click--> manage-->request tab, check the reporting symbol for newly loaded request.
3. Check aggregates are filled properly.
4 if your loading thru process chains, check the process chains logs of last 3 days loads. If any porcess chain has failed during dtp load or filling of aggreates. rectify the error and reload the step.
Thru above points you may find some clue.
Thanks
