Hi,
MB5B in "valuated stock" option reads data from MBEW table as a base and then reads the corresponding valuated material documents and accounting documents (BSIM table) for the date range. This will consider the movement only if there is an accounting document.
But if its executed in "Storage Location Stock" option, it considers the stock tables (like MARD) as base data and then reads the corresponding material documents (MSEG) for the date range. It considers all material documents irrespective of whether there is an accounting entry or not.
