Runtime error CL_FPM_TREE_RENDERING - charge calculation & freight settlement

Hi Experts,

I am facing an issue related to viewing the charges and freight settlement document in NWBC. The issues are as follows :

1. I run calculate charges function which gives a message that "Charge calculation successful" but as soon as I go into the freight order and try to view the charges tab, it gives an internal server error. (The screen shots are appended herewith)

2. Similarly when I go to freight order and as a follow up document I try to create freight settlement document, but same issue persists in this case as well.  (The screen shots are appended herewith)

Kindly help me in this regard.

Thanks & Regards,
