I have create a Employee Salary.dbf with six fields namely 1. Basic pay 2. Special Pay 3. Dearnes pay 4. House rent allowance 5. Transport allowance 6. Gross pay .

For every year July The "Basic pay" (Field) will automatically increased by 3% for every Epmloyees.

Let assume the "Basic pay" of a employee now is =7500, next year july it will automatically increased by 3%. The formula is 7500*0.03 = 225. so the basic pay of employee for next year july is 7500+225 = 7725.
