Journal Line Amount differs from the Line Drill down amount

Hello Experts,

We are facing an issue in few of Journal Lines. These were from imported from Cost Management module and comprises several transactions (SLA transactions).

Once these were created into one single Journal the amount is different.

For Ex: Journal Line Amount Says 80$. But in Line Drill down, it has 10 different SLA transaction of each 10$ (total 100$).

In my understanding, this 100$ amount should be displayed as line amount in Journal.

Any pointers to understand this discrepancy will be highly appreciated.

Thanks,

Satheesh
