Need to Update MSEG-EXBWR when posting GR with Reservation via MIGO

Hello All,

As part of my requirement where i suppose to update the field MSEG-EXBWR when we post GR with reservation for a movement type like 262. I have tried by below two methods but could not update the same.

Badi (MB_MIGO_BADI-LINE_MODIFY):

When i tried to update the field MSEG-EXBWR using MB_MIGO_BADI with method LINE_MODIFY it is throwing warning message "Field GOITEM-EXBWR not ready to accept input (Change will not be adopted)" and not updating the value in that field.

Exit MB_CF001 (EXIT_SAPLMBMB_001):

In this case i am not getting any error/warning however still that field is not getting updated.

Please let me know if another BADI/Exit or settings needs to done for this field.

Thanks
