Other Customizing table records are used to define to fill MVER and DVER tables, like T156M (T156M-KZVBL "+/- sign for consumption update in material master record") So if you want to replicate MVER from MSEG you should also use MSEG-BUSTM (For ME* or MCS* strings often associated to code movement 101 the flag is not set in T156M, when for strings like MA* the flag is set to "+")
