Bapi MM MRP Area upload remote

Hi Experts,

I am use BAPI BAPI_MATERIAL_SAVEDATA to upload material master MRP view from an external application.

To upload the MRP Area field in SAP can use MD_MRP_LEVEL_CREATE_DATA, but this function module (FM) and its cause is not obtained from an external application

Anybody knows what BAPI can I use for this field?

Who knows how to use the BAPI (not FM) upload MRP area?

Thanks in advance!

Regards,

Maxim
