Basis for EE PF Contribution - "eligible pay or pf basis whichever is less" not working

Hi,

For a particular group of employees, we want to restrict EE PF basis to 6500 in case it exceeds the amount.  We selected Eligible pay or pf basis whichever is less option  for employee contribution in infotype 587 in PA30 and also the constant PFBAS = 6500 is maintained in table T511P .  Still when I run payroll /111 is not 6500 and EE PF COntirbution is based on Basic + DA (which exceeds 6500).

What can be done to resolve this?

Regards
