GOSI slab rate change T7SA13

Hi Team,

Due to saudi GOSI change for SAUDI nationals from September , I have to change the GOSI slab in table T7SA13 by delimiting  as the attached screen shot . But after this I am facing issue in payroll. If I change then data from 01.01.1900 its working fine but then payroll will throw retro. Please let me know how I will change the slab rate

Thanks
