Add Freight unit to Freight Order .

Hi guys .

I need to assign the resource and FU to a newly created FO.

I try to use ADD_FU_BY_FUID. but dump is occurred.

i read this document where says:

Transportation Management Missing Functions/User expectations - Freight Order Management

The document says:

Freight unit cannot be added to Freight Order via BOPF

You cannot add a Freight Unit via action ADD_FU_BY_FUID to Freight Order because a dump is occured. The standard way is to add FUs to FROs on the UI. The Test tool used for business is not supported.

How can i do it in my code? .please help me my requeirement is urgent.

Please see my code attached.
