Questions about how to get social security field in the payment process request

What we want is to show the employee's social security field in the PPR output. From my analysis, in the early version of the script, it is stored in the LegalEntityRegistrationNumber field. But in later version, it has been removed.

So why is it removed and is it available again in the later and later version or is there any workaround for same now
