Hi @SMANUEL 

Can you provide  a screen shot of the “Demand” tab. Make sure you capture the “Required Date” field

Best Regards,
Tharaka.

@Tharaka Senevirathne Thank You for the response..

Earlier we had modified the Required dates of all the existing demands on this particular Activity, to be within the Early Start & Finish dates..

To our surprise, we were able to change the dates the very next day!!

Thanks Much

Hi @SMANUEL 

If the required dates of all the demand lines are within the Early Start & Finish dates, I believe this issue needs in depth investigation. Hence creating a ticket to IFS support is the best solution I can think of.

@Tharaka Senevirathne will do that next time ..Thanks Much
