budget column includes the assigned values in 558 report

Hello Experts,

Again I am back with a query, for a perticular project S_ALR_87013558 report shows the budget values different than CJ31.

When i did analysis found budget column sum up the KBUD & KBFC values and display the figures in 558 report or in other words The system is adding the actuals (or assigned, both are same as we have commitment as zero) to the budget  column in the display of the 558 report.

Please help me out of this dilemma, why system calculates the wrong values in 558 whereas CJ31 has the correct values.

Thanks,

Vindhesh
