On my ‘Researcher Details’ page, my affiliation record does not cover my entire career. Why?

From the KAKEN Database, the system extracts all affiliations, departments and job titles listed in application forms and reports of the research projects in which the researcher has participated, and integrates and displays them in ‘Affiliation’ on the ‘Researcher Details’ page.
For the fiscal years whose information on adopted projects is not registered on the KAKEN Database, the affiliation information will not be reflected in ‘Researcher Details’.
