Hi Paul, what do you mean by 'displaying order type 51'? Can you please provide any screenshot? Forecast order saved in liveCahce is with order type 51 'gc_om_forecast_order', so should be the correct order ...
Also there're several reasons for 'forecast orders are not displayed', like
1)Consumption situation - You'll need to see the forecasts in /sapapo/rrp3 first.
2)Key figure setting (refer to note 1821733).
Best Regards,
Ada
