Hi Ada,
An important piece of info which I have left out. Yes we have a Time Stream ID assigned but up until a few weeks agao the time stream with the "Period Calendar" (No Gaps) but we have changed this to the "Working Time Calendar" (with gaps).
We believe that the time series is correct as it only shows the working days (Mon to Fri) and this also excludes our public holidays.
The issues is te change from the 7 day calendar to the 5 day calendar and how SAP still retains the information based on the 7 days.
Regards
Paul
