Load Flat File from PSA to Cube in SAP BW

Hi Experts,

I have added a new info Object - Business Division 3 in Cube.

When I add it , the compounding attribute of business division 3 which are bus div 1 and bus div 2 are also added in cube..

Then I added Business division 3 in the flat file datasource and mapped in the transformation from Data source (Flat File ) to Cube.

But didnt map business div 2 and business division 1.

But when I am trying to load the data from PSA to Cube , it is getting failed and showing error as "Process Terminated".

What could be the reason for this and how can I rectify it?

Best Regards,

Abhimanyu Sharma.
