Hello Ranjit,
After manager changes in HR system, do you see the entry for the personal number in Table: HRLDAP_PERNR
This is table from where delta records are picked up, I guess manager field changes are not configured to add entries in table HRLDAP_PERNR , Please have a check with any ABAP'er to debug the BADI's
Ideally if its happening with full load then Delta should also do the job.
