Hi JK
MRS represents DURATION on the GANTT chart. It osunded strange to me first but when you think that the actual scheduling BLOCKS/ASSIGNS a resource during the time of the duration.Representing by WORK in the GANTT chart will make things confusing: assume that you will need 200 hrs of work for 100 resources for one operation. If you use WORK in the GANTT Chart, you will have 200 hrs of demand for which potentially you will never find any resource available. But if you represent it per duration, then the demand will only show 2 hrs of requirement in the GANTT chart and when you start assigning individuals, if there is still remaining work, MRS will indicate the demand as "not fully scheduled".
Now there is a setting in configuration (existing in MRS 10.0, maybe this existed in MRS 8.0 but I am not sure), which gives the flexibility to use work or demand in MRS-PM integration. But I don't think that will resolve your issue as to me that is not an issue unless I am missing something.
Check the duration logic in the above setting.
If you still feel something wrong, can you step by step put together the screen shots/menu paths as it will be useful to see how are you generating the assignments.
I hope this helps.
