Error in Master Planning - MRP

Hi There,

I have specified the working time but still getting following error:


I tried to debug \Classes\ReqCalcScheduleItemTable\run - line 8

public void run()
void doError()
if (!isReqLogMerged)
hasErrors = true;

Not sure why this error is popping up

Kindly advice

The issue was resolved by adding working calendar till 31 december 2022 previously it was set to 31 december 2021
