Hi Vijay,
Just try follow these General steps:
1. Include direct charge in calculation sheet. if still it is not picked, it means you have a calculation sheet issue. then check settings in Calculation sheet.
2. If yes, the problem is rate table.
Very Generic and Starting Settings required for Charge Calculation are:
1. Create a charge type.
2. Create FA, Calculation sheet, Rate table and Scales.
3. Create BP and Org. Data
4. Define General Settings and Calculation profile.
Hope it helps.
Regards
Nitesh
