How to add Special Information Type in Self service HR

In Core HR, SIT can be added and filtered on different forms through the taskflow/node/custom form features.
This set up is to map the access to the forms and the data with HR People business needs.

SSHR is dedicated to Employees and Managers and so the logical of the Product can be different in some points.

In SSHR, Special Information are handled through dedicated functions:
for Employees, through the seeded function HR_SIT_SS
for Managers, through the seeded function HR_SIT_MGR_SS

By default, all Special Information activated through the HRMS Manager responsibility are displayed in SSHR.
