In the regular SAP 4.7 system what are the various metrics one can draw out for the forecast in order to check the efficiency and accuracy of the forecast ? Something like an MLE, Theil's coefficent, MAD, MAPE etc. Also how can one calculate them and then later view them ?
You have this on APO but not on R3. On APO you have ET, MAD, MSE, RMSE, MAPE, MPE, APE, APE-A, MdAPE, MdRAE, GMRAE, RAE... and others.
