Hi,

U can use SQL Trace ST05 and ABAP Runtime Analysis (t/code SE30) to measure your program performance. ABAP Runtime Analysis has Tips and Tricks to improve the program performance.

I will list out some of the points to write a better program.

1.first of all the algorithm should be good.

2.U should avoid redundant code.

3.Avoid Select * statement.

4.Use debugger to view how ur program works, to make proper adjustments to ur code.
