Loan outstanding amount NIL in FI but not in HCM !!!

Hi Experts,

I am facing problem in loan outstanding.

While running the T-Code PC00_M99_CLOG in HCM, it shows the outstanding amount, however when I check employee vendor account in FI outstanding and it is NIL. 

I would like to know, how it happened ?

As employee has left the company, how can I recovered this from payroll side ?

what would be possible way-out to resolve this ?

Please give your valuable input here.

Regards,

Ritu
