Function for
Allowing Multiple Personnel Numbers to Use Identical SSN 
Description
It is now possible to assign multiple personnel numbers to the same Social Security Number on Infotype 0002 (Personal Data). This is checked by a new feature, SSNCK.
This feature can be defined so that when you
enter a duplicate Social Security Number on Infotype 0002, the system
either:
- permits the duplicate SSN without issuing a warning or error message
- permits the duplicate SSN and issues a warning message
- issues an error message and does not permit the duplicate SSN
Change system parameters in customizing
You can activate this feature in the Personnel Administration IMG: Personal Data -> Personal Data -> Enable/disable Social Security Number audits.
