Wrong calculation of

!!!!!!!!!!!!!!!!! Most Urgent

Dear All,

I need to process arrears for the period April 2014 to Nov. 2014. At all places calculation is accurate but in form 16, It is showing 18101.56 instead of 17508.42 as per projection report & manual calculation.

Arrears Calculation details :-

BASIC                                        7269.24

ADA                                             363.46

CON                                           6734.62

FDA                                          53047.22

FESTIVAL ALLOWANCE               181.96

Periodical Allowance                    2960.00

VDA                                         -53048.08

Total                                          17508.42

System is adding 593.48 in account of /ARB(CF Perk value:housing)

If we go as per rule then it Perk Value housing should be 7.5% of earned arrears & added in Accommodation(Perquisites).

Please help me out that on what basis, SAP is calculation /ARB(593.14).

Thanks & regards
