Hi Ravi,
It is possible to have a DSO for Goods Movements and Revaluations. If you want to use the classic Inventory Management scenario (using non-cumulative key figures), then you cannot use a similar approach with Stock Initialization. This is normally also not necessary since such a Stock Initialization reflects the current situation, i.e. should be possible using ECC. This has to go directly to the Inventory InfoCube.
Please review SAP Note 581778 - ODS capability of extractors from inventory management and the related SAP Notes carefully for more information.
Best regards,
Sander
