i am new to Forecasting concept but having a issue. please help me.
in MD04 purchase requisition is not showing. i checked the material master & found that the forecast values are blank & in the log
the following error message showing.
>time series characterstics changed.
>forecast values will be nagative
>Ex-post forecast carried out
>safety stock not calculated as service level =0
could you please let me know if this might be the reason for PR being not generated in MD04 & what rectification needs to be done.
Any help will be highly appreciated.
Thanks & Regards,
