I have a doubt regarding the cube unprocess and process full procedure that, Do I need to unprocess all dimensions and then only do unprocess to cube and after doing process full to all dimensions, then only I can do process full with cube.
Am I doing right? If not please suggest me the correct way to do unprocess and process full of the cube ASAP.
As you can find here :
https://msdn.microsoft.com/en-us/library/ms174774.aspx
Process full :
Processes an Analysis Services object and all the objects that it contains. When Process Full is executed against an object that has already been processed, Analysis Services drops all data in the object, and then processes the object. This kind of processing is required when a structural change has been made to an object, for example, when an attribute hierarchy is added, deleted, or renamed.
So unprocess your cube is unnecessary.
If you want to make simple, just Process Full you SSAS Database, Cube and Dimensions will be refreshed.
Hope this help,
