For existing organizations (where you have performed at least one payroll run), perform the following steps to change its IDW calculation method:
In the Organization window, query for the GRE you want to configure.
Select GRE/Legal Entity, and click Others.
Select Social Security Details, and click OK.
Click in the field of the Additional Organization Information window to open the Social Security Details window.
Choose your new IDW calculation method.
Save your work.
If you are switching to the Factor Table method, follow the steps described in "Set up fixed earnings IDW, Factor Table method," Setting Up IDW.
If you are switching to the Earnings method, remove any IDW Factor Table names from the Integrated Daily Wage element.
Save your work.
These steps trigger an IDW change event, and HRMS will archive the affected employee records the next time you run the Social Security Archiver.
Oracle HRMS and the Social Security Archiver cannot detect changes made to an existing IDW factor table. If you need to make changes to an existing factor table, you must delete the original table and create a new one.
