Inventory cube with Movement Type

In standard Inventory cube 0IC_C03 we have added movement type and loaded the data(followed the process exactly as mentioned in the How to handle Inventory management and compressed).

After loading the data materialwise valuated stock qty and value is matching, but when we drill down movement typewise(for ex.101,102 etc) data is not matching with R/3.All 101 movement types showing in negative values.

Do we have to do any changes in the standard routines if we add movement types in the cube 0IC_C03?.We are loading the data based on processing keys as per the standard routines.

Please help me with your inputs.

Thanks in advance..
