Payroll rounding and rounding recovery (KSA)

greetings

i have a question regarding the payroll rounding and rounding recovery in KSA localization , after searching i found out the table V_T7M9Y1

is responsible for defining the rounding rules, but it still doesnt affect /560 in payroll...is there anything else to be done other than maintaing the previously mentioned table ??

also

if i want to set a maximum limit for the cumulation of gratuity provision what should i do?

ex: gratuity provision for 1 employee is 1000 SR/month and i have 100 employees in the company so the total gratuity provisions mpnthy is 100,000SR

so what should i do to make the system stops cumulation provisions when it reach this amount ?

thanks
