BAPI_PO_CREATE1 bapi - creating subcontracts using this bapi

Hi Experts,

I am trying to create POs with subcontracts. I have two structures POCOMPONENTS and POCOMPONENTSX to achieve. but two fields 'REQUIREMENT CATEGORY and GRID SIZE' fields are missing these structures.

Could you please guide/suggest me how to pass the above two fields also? or do i need to implement any notes to have these 2 fields also in these structures?

Note: I am able to create subcontracts for POs without these two fields also but the requirement is to pass these two fields also.

Please suggest!! as this is an urgent requirement.

Thanks
