Hi,
May I know why huge number of custom movement types? Could you please explain the logic behind 400+ custom movement types!!! Custom movement types are created on special / rare cases, where you want to distinguish / need a different posting.
There is no option to create the movement types in mass, since the custom movement types can be created by copying a standard movement type and you can do minor changes only in the new movement type. This changes are critical and has to be done carefully!. If the same field changes are to be done in all the custom movement types, you may check the option of LSMW as well.
As already suggested, its a configuration step and has to be transported from Golden client to required instances. You may create the custom movement type and save it in TR and move the same.
