Cannot see Transaction Data after upgrade to BW7.4SP13

Hi,

We have recently upgrade our BW system from BW 7.0 to BW 7.4SP13 and upgraded the Oracle from 11.2.0.2 to 12.0.1.0 and RHL5 to RHL7 and converted the data from non-unicode to Unicode.

After the tasks, when we come in the system and right click on the cubes and try to display the data, the data screen is blank.

The Basis team has checked the database and the DB size still looks similar to our Production copy.

We have run a series of post upgrade steps, including rebuilding the OLAP Cache, but still it doesn't display the data in the cube. We checked the E and F tables, they show 0 records.

I am not sure what steps to be performed next. Has anyone faced similar issue?

Your help will be greatly appreciated. We are taking a critical hit on the project timelines.

Thanks,

Abhishek
