SAP Payroll Saudi Arabia - Gosi Split issue

I faced the following issue in GOSI Calculation

This issue exist in case the employee has transfer through more than one cost center, SAP not generate GOSI based Value properly

Example:

Employee No XXXX has transferred between 3 project in same month

(proj 01: 9 days, proj 02: 3 days, proj 03: 20 days) Basic salary 12000 & Housing 2000

After Payroll calculate we get GOSI amount 1645

I checked the schema SA22 and find as below

/370 1 2000

/370 2 4000

/370 3 6000

/660 1 2000

/660 2 4000

/660 3 6000
