Unloading Point is non -editable in MIGO for Movt type 543

Hello folks,

While creating a GR against a subcontracting Purchase Order the unloading point (ABLAD) in component segment (Movt type 543 O) in MIGO screen is appearing as non editable. We have tried all the options like, OMJX, OMJJ, OMCJ,etc. But nothing was helpful.

We want ABLAD as ready for input and editable field in MIGO . Please help in this regard.

Thanks
