Hi Rahul ,
Yes Plan data never gets loaded through transformation. We have Transactional cubes to take care of planning data in sap bw.
They work based upon the following principle:
- Transactional Cube Can Be Loaded with Data. Planning Not Allowed
In this operation mode, you can supply the InfoCube with data from transaction systems using a Data Source. As long as the Info Cube is in this operation mode, no data can be updated directly with the means of SEM. - Transactional Cube Can Be Planned. No Data Loading Allowed
In this operation mode, you can directly update data from SEM-BPS into the InfoCube. A provision of data using DataSources is not possible in this operation mode.
Please check http://help.sap.com/saphelp_sem320bw/helpdata/en/7b/a90e78d10311d4b3490050dadfb23f/content.htm
You can simply R click + display data to see the data .
Thanks
