Hi,
If you change the consumption posting indicator, it will affect the consumption posting (MVER / DVER tables).
Once you change the consumption indicator to blank (no consumption update), the movement happend after the change wont update in consumption history tables, and the same wont show in material master consumption history.
But the previous quantities will be always there in the tables and the previous consumption history includes these movement types also. In order to update the consumption history, you may create the report mentioned / attached in the note: 1832196 - General information on consumption update MVER/DVER and run the report. The report will automatically correct the consumption history based on the current movement type configuration.
