gratuity Exemption

hi all

As per our company policy we are apying the gratuity amount to the employees,but the problem is that the exemption in perks column is reflecting in 1st settlement,but not in 2nd settlement.

Means thewage type is not getting generated if i run payroll 2nd time for any left employees.

Also i ve found out two PCRs which is written at the time of implementation

ZGTE

/4E8 Gratuity Contribution Exemption

ZERO= NRA

ADDWT *

Rule ZGT1

3110 customize wagetype for gratuity exemtion

ADDWT *

ZERO=NR

ADDWT /4E8

is there is any mistake in the above 2 rules ???
