Hi Mark101,
This is working as per the design.
The actuals entered thru scheduler(OWB/MSP) is not considered a financial transaction and hence it does not end up in WIP table. The cost plan gets the actuals from the WIP table.
If you have PMO installed, you should see a portlet - Posted Transaction Review. This portlet pulls data from the WIP table. Only those actuals in this portlet is expected to show up in the CP.
Actuals entered through scheduler will reflect in the assignment(ACWP) but not in the cost plan.
If you want actuals to show up in CP, it should either be entered via timesheets or transaction entry.
Hope this helps, if not please let us know your questions.
Thanks,
Jerin
