Scheduling Fields: Start and End Date, Planned Effort and Spent Effort
The Start/End date and Planned Effort/Spent Effort fields are imported from the appropriate Task fields of MS Project. The Durations like "1day" is automatically converted to the appropriate number of hours (8h) according to the Duration conversion rules described earlier.
These fields are typically calculated or updated by MS Project during the work in MS Project, therefore these are likely will be changed.
* 
the Planned Effort and Spent Effort fields are calculated fields in Codebeamer, and they may change next time when you update a work item of the imported items. However the importer will disable these calculations during import simply to get the same values calculated by MS Project. If you don't want these fields be overwritten by Codebeamer then you should reconfigure the tracker and disable propagation and calculation for these fields.
