upload forecast in MC88 or MC94 background

Hello Experts,

I have tried to upload forecast data using MC88 and MC94 using BDC but both are not working in background.Error No batch input data for screen SAPMMCP6 0110(for Mc94 tcode).

Ataul requirement is to upload forecast in MC88 or MC94 after transaction MC74 should be called for each material to transfer  the forecast to demand planning.

Can anyone please let me know what is the best solution to achieve this. i know it can be done via BAPI or Idoc but would like to check the best possibilities

Thanks In advance

best regadrs
